December’s Reimagining Democracy Workshop

Imagine that we’ve all—all of us, all of society—landed on some alien planet, and we have to form a government: clean slate. We don’t have any legacy systems from the US or any other country. We don’t have any special or unique interests to perturb our thinking.

How would we govern ourselves?

It’s unlikely that we would use the systems we have today. The modern representative democracy was the best form of government that mid-eighteenth-century technology could conceive of. The twenty-first century is a different place scientifically, technically and socially.

For example, the mid-eighteenth-century democracies were designed under the assumption that both travel and communications were hard. Does it still make sense for all of us living in the same place to organize every few years and choose one of us to go to a big room far away and create laws in our name?

Representative districts are organized around geography, because that’s the only way that made sense 200-plus years ago. But we don’t have to do it that way. We can organize representation by age: one representative for the thirty-one-year-olds, another for the thirty-two-year-olds, and so on. We can organize representation randomly: by birthday, perhaps. We can organize any way we want.

US citizens currently elect people for terms ranging from two to six years. Is ten years better? Is ten days better? Again, we have more technology and therefor more options.

Indeed, as a technologist who studies complex systems and their security, I believe the very idea of representative government is a hack to get around the technological limitations of the past. Voting at scale is easier now than it was 200 year ago. Certainly we don’t want to all have to vote on every amendment to every bill, but what’s the optimal balance between votes made in our name and ballot measures that we all vote on?

In December 2022, I organized a workshop to discuss these and other questions. I brought together fifty people from around the world: political scientists, economists, law professors, AI experts, activists, government officials, historians, science fiction writers and more. We spent two days talking about these ideas. Several themes emerged from the event.

Misinformation and propaganda were themes, of course—and the inability to engage in rational policy discussions when people can’t agree on the facts.

Another theme was the harms of creating a political system whose primary goals are economic. Given the ability to start over, would anyone create a system of government that optimizes the near-term financial interest of the wealthiest few? Or whose laws benefit corporations at the expense of people?

Another theme was capitalism, and how it is or isn’t intertwined with democracy. And while the modern market economy made a lot of sense in the industrial age, it’s starting to fray in the information age. What comes after capitalism, and how does it affect how we govern ourselves?

Many participants examined the effects of technology, especially artificial intelligence. We looked at whether—and when—we might be comfortable ceding power to an AI. Sometimes it’s easy. I’m happy for an AI to figure out the optimal timing of traffic lights to ensure the smoothest flow of cars through the city. When will we be able to say the same thing about setting interest rates? Or designing tax policies?

How would we feel about an AI device in our pocket that voted in our name, thousands of times per day, based on preferences that it inferred from our actions? If an AI system could determine optimal policy solutions that balanced every voter’s preferences, would it still make sense to have representatives? Maybe we should vote directly for ideas and goals instead, and leave the details to the computers. On the other hand, technological solutionism regularly fails.

Scale was another theme. The size of modern governments reflects the technology at the time of their founding. European countries and the early American states are a particular size because that’s what was governable in the 18th and 19th centuries. Larger governments—the US as a whole, the European Union—reflect a world in which travel and communications are easier. The problems we have today are primarily either local, at the scale of cities and towns, or global—even if they are currently regulated at state, regional or national levels. This mismatch is especially acute when we try to tackle global problems. In the future, do we really have a need for political units the size of France or Virginia? Or is it a mixture of scales that we really need, one that moves effectively between the local and the global?

As to other forms of democracy, we discussed one from history and another made possible by today’s technology.

Sortition is a system of choosing political officials randomly to deliberate on a particular issue. We use it today when we pick juries, but both the ancient Greeks and some cities in Renaissance Italy used it to select major political officials. Today, several countries—largely in Europe—are using sortition for some policy decisions. We might randomly choose a few hundred people, representative of the population, to spend a few weeks being briefed by experts and debating the problem—and then decide on environmental regulations, or a budget, or pretty much anything.

Liquid democracy does away with elections altogether. Everyone has a vote, and they can keep the power to cast it themselves or assign it to another person as a proxy. There are no set elections; anyone can reassign their proxy at any time. And there’s no reason to make this assignment all or nothing. Perhaps proxies could specialize: one set of people focused on economic issues, another group on health and a third bunch on national defense. Then regular people could assign their votes to whichever of the proxies most closely matched their views on each individual matter—or step forward with their own views and begin collecting proxy support from other people.

This all brings up another question: Who gets to participate? And, more generally, whose interests are taken into account? Early democracies were really nothing of the sort: They limited participation by gender, race and land ownership.

We should debate lowering the voting age, but even without voting we recognize that children too young to vote have rights—and, in some cases, so do other species. Should future generations get a “voice,” whatever that means? What about nonhumans or whole ecosystems?

Should everyone get the same voice? Right now in the US, the outsize effect of money in politics gives the wealthy disproportionate influence. Should we encode that explicitly? Maybe younger people should get a more powerful vote than everyone else. Or maybe older people should.

Those questions lead to ones about the limits of democracy. All democracies have boundaries limiting what the majority can decide. We all have rights: the things that cannot be taken away from us. We cannot vote to put someone in jail, for example.

But while we can’t vote a particular publication out of existence, we can to some degree regulate speech. In this hypothetical community, what are our rights as individuals? What are the rights of society that supersede those of individuals?

Personally, I was most interested in how these systems fail. As a security technologist, I study how complex systems are subverted—hacked, in my parlance—for the benefit of a few at the expense of the many. Think tax loopholes, or tricks to avoid government regulation. I want any government system to be resilient in the face of that kind of trickery.

Or, to put it another way, I want the interests of each individual to align with the interests of the group at every level. We’ve never had a system of government with that property before—even equal protection guarantees and First Amendment rights exist in a competitive framework that puts individuals’ interests in opposition to one another. But—in the age of such existential risks as climate and biotechnology and maybe AI—aligning interests is more important than ever.

Our workshop didn’t produce any answers; that wasn’t the point. Our current discourse is filled with suggestions on how to patch our political system. People regularly debate changes to the Electoral College, or the process of creating voting districts, or term limits. But those are incremental changes.

It’s hard to find people who are thinking more radically: looking beyond the horizon for what’s possible eventually. And while true innovation in politics is a lot harder than innovation in technology, especially without a violent revolution forcing change, it’s something that we as a species are going to have to get good at—one way or another.

White House Announces AI Cybersecurity Challenge

At Black Hat last week, the White House announced an AI Cyber Challenge. Gizmodo reports:

The new AI cyber challenge (which is being abbreviated “AIxCC”) will have a number of different phases. Interested would-be competitors can now submit their proposals to the Small Business Innovation Research program for evaluation and, eventually, selected teams will participate in a 2024 “qualifying event.” During that event, the top 20 teams will be invited to a semifinal competition at that year’s DEF CON, another large cybersecurity conference, where the field will be further whittled down.

[…]

To secure the top spot in DARPA’s new competition, participants will have to develop security solutions that do some seriously novel stuff. “To win first-place, and a top prize of $4 million, finalists must build a system that can rapidly defend critical infrastructure code from attack,” said Perri Adams, program manager for DARPA’s Information Innovation Office, during a Zoom call with reporters Tuesday. In other words: the government wants software that is capable of identifying and mitigating risks by itself.

This is a great idea. I was a big fan of DARPA’s AI capture-the-flag event in 2016, and am happy to see that DARPA is again inciting research in this area. (China has been doing this every year since 2017.)

Backdoor in TETRA Police Radios

Seems that there is a deliberate backdoor in the twenty-year-old TErrestrial Trunked RAdio (TETRA) standard used by police forces around the world.

The European Telecommunications Standards Institute (ETSI), an organization that standardizes technologies across the industry, first created TETRA in 1995. Since then, TETRA has been used in products, including radios, sold by Motorola, Airbus, and more. Crucially, TETRA is not open-source. Instead, it relies on what the researchers describe in their presentation slides as “secret, proprietary cryptography,” meaning it is typically difficult for outside experts to verify how secure the standard really is.

The researchers said they worked around this limitation by purchasing a TETRA-powered radio from eBay. In order to then access the cryptographic component of the radio itself, Wetzels said the team found a vulnerability in an interface of the radio.

[…]

Most interestingly is the researchers’ findings of what they describe as the backdoor in TEA1. Ordinarily, radios using TEA1 used a key of 80-bits. But Wetzels said the team found a “secret reduction step” which dramatically lowers the amount of entropy the initial key offered. An attacker who followed this step would then be able to decrypt intercepted traffic with consumer-level hardware and a cheap software defined radio dongle.

Looks like the encryption algorithm was intentionally weakened by intelligence agencies to facilitate easy eavesdropping.

Specifically on the researchers’ claims of a backdoor in TEA1, Boyer added “At this time, we would like to point out that the research findings do not relate to any backdoors. The TETRA security standards have been specified together with national security agencies and are designed for and subject to export control regulations which determine the strength of the encryption.”

And I would like to point out that that’s the very definition of a backdoor.

Why aren’t we done with secret, proprietary cryptography? It’s just not a good idea.

PIPEDREAM Malware against Industrial Control Systems

Another nation-state malware, Russian in origin:

In the early stages of the war in Ukraine in 2022, PIPEDREAM, a known malware was quietly on the brink of wiping out a handful of critical U.S. electric and liquid natural gas sites. PIPEDREAM is an attack toolkit with unmatched and unprecedented capabilities developed for use against industrial control systems (ICSs).

The malware was built to manipulate the network communication protocols used by programmable logic controllers (PLCs) leveraged by two critical producers of PLCs for ICSs within the critical infrastructure sector, Schneider Electric and OMRON.

Cyberwar Lessons from the War in Ukraine

The Aspen Institute has published a good analysis of the successes, failures, and absences of cyberattacks as part of the current war in Ukraine: “The Cyber Defense Assistance Imperative ­ Lessons from Ukraine.”

Its conclusion:

Cyber defense assistance in Ukraine is working. The Ukrainian government and Ukrainian critical infrastructure organizations have better defended themselves and achieved higher levels of resiliency due to the efforts of CDAC and many others. But this is not the end of the road—the ability to provide cyber defense assistance will be important in the future. As a result, it is timely to assess how to provide organized, effective cyber defense assistance to safeguard the post-war order from potential aggressors.

The conflict in Ukraine is resetting the table across the globe for geopolitics and international security. The US and its allies have an imperative to strengthen the capabilities necessary to deter and respond to aggression that is ever more present in cyberspace. Lessons learned from the ad hoc conduct of cyber defense assistance in Ukraine can be institutionalized and scaled to provide new approaches and tools for preventing and managing cyber conflicts going forward.

I am often asked why where weren’t more successful cyberattacks by Russia against Ukraine. I generally give four reasons: (1) Cyberattacks are more effective in the “grey zone” between peace and war, and there are better alternatives once the shooting and bombing starts. (2) Setting these attacks up takes time, and Putin was secretive about his plans. (3) Putin was concerned about attacks spilling outside the war zone, and affecting other countries. (4) Ukrainian defenses were good, aided by other countries and companies. This paper gives a fifth reason: they were technically successful, but keeping them out of the news made them operationally unsuccessful.

What Will It Take?

What will it take for policy makers to take cybersecurity seriously? Not minimal-change seriously. Not here-and-there seriously. But really seriously. What will it take for policy makers to take cybersecurity seriously enough to enact substantive legislative changes that would address the problems? It’s not enough for the average person to be afraid of cyberattacks. They need to know that there are engineering fixes—and that’s something we can provide.

For decades, I have been waiting for the “big enough” incident that would finally do it. In 2015, Chinese military hackers hacked the Office of Personal Management and made off with the highly personal information of about 22 million Americans who had security clearances. In 2016, the Mirai botnet leveraged millions of Internet-of-Things devices with default admin passwords to launch a denial-of-service attack that disabled major Internet platforms and services in both North America and Europe. In 2017, hackers—years later we learned that it was the Chinese military—hacked the credit bureau Equifax and stole the personal information of 147 million Americans. In recent years, ransomware attacks have knocked hospitals offline, and many articles have been written about Russia inside the U.S. power grid. And last year, the Russian SVR hacked thousands of sensitive networks inside civilian critical infrastructure worldwide in what we’re now calling Sunburst (and used to call SolarWinds).

Those are all major incidents to security people, but think about them from the perspective of the average person. Even the most spectacular failures don’t affect 99.9% of the country. Why should anyone care if the Chinese have his or her credit records? Or if the Russians are stealing data from some government network? Few of us have been directly affected by ransomware, and a temporary Internet outage is just temporary.

Cybersecurity has never been a campaign issue. It isn’t a topic that shows up in political debates. (There was one question in a 2016 Clinton–Trump debate, but the response was predictably unsubstantive.) This just isn’t an issue that most people prioritize, or even have an opinion on.

So, what will it take? Many of my colleagues believe that it will have to be something with extreme emotional intensity—sensational, vivid, salient—that results in large-scale loss of life or property damage. A successful attack that actually poisons a water supply, as someone tried to do in January by raising the levels of lye at a Florida water-treatment plant. (That one was caught early.) Or an attack that disables Internet-connected cars at speed, something that was demonstrated by researchers in 2014. Or an attack on the power grid, similar to what Russia did to the Ukraine in 2015 and 2016. Will it take gas tanks exploding and planes falling out of the sky for the average person to read about the casualties and think “that could have been me”?

Here’s the real problem. For the average nonexpert—and in this category I include every lawmaker—to push for change, they not only need to believe that the present situation is intolerable, they also need to believe that an alternative is possible. Real legislative change requires a belief that the never-ending stream of hacks and attacks is not inevitable, that we can do better. And that will require creating working examples of secure, dependable, resilient systems.

Providing alternatives is how engineers help facilitate social change. We could never have eliminated sales of tungsten-filament household light bulbs if fluorescent and LED replacements hadn’t become available. Reducing the use of fossil fuel for electricity generation requires working wind turbines and cost-effective solar cells.

We need to demonstrate that it’s possible to build systems that can defend themselves against hackers, criminals, and national intelligence agencies; secure Internet-of-Things systems; and systems that can reestablish security after a breach. We need to prove that hacks aren’t inevitable, and that our vulnerability is a choice. Only then can someone decide to choose differently. When people die in a cyberattack and everyone asks “What can be done?” we need to have something to tell them.

We don’t yet have the technology to build a truly safe, secure, and resilient Internet and the computers that connect to it. Yes, we have lots of security technologies. We have older secure systems—anyone still remember Apollo’s DomainOS and MULTICS?—that lost out in a market that didn’t reward security. We have newer research ideas and products that aren’t successful because the market still doesn’t reward security. We have even newer research ideas that won’t be deployed, again, because the market still prefers convenience over security.

What I am proposing is something more holistic, an engineering research task on a par with the Internet itself. The Internet was designed and built to answer this question: Can we build a reliable network out of unreliable parts in an unreliable world? It turned out the answer was yes, and the Internet was the result. I am asking a similar research question: Can we build a secure network out of insecure parts in an insecure world? The answer isn’t obviously yes, but it isn’t obviously no, either.

While any successful demonstration will include many of the security technologies we know and wish would see wider use, it’s much more than that. Creating a secure Internet ecosystem goes beyond old-school engineering to encompass the social sciences. It will include significant economic, institutional, and psychological considerations that just weren’t present in the first few decades of Internet research.

Cybersecurity isn’t going to get better until the economic incentives change, and that’s not going to change until the political incentives change. The political incentives won’t change until there is political liability that comes from voter demands. Those demands aren’t going to be solely the results of insecurity. They will also be the result of believing that there’s a better alternative. It is our task to research, design, build, test, and field that better alternative—even though the market couldn’t care less right now.

Recreating Democracy

Last week, I hosted a two-day workshop on recreating democracy.

The idea was to bring together people from a variety of disciplines who are all thinking about different aspects of democracy, less from a “what we need to do today” perspective and more from a blue-sky future perspective. My remit to the participants was this:

The idea is to start from scratch, to pretend we’re forming a new country and don’t have any precedent to deal with. And that we don’t have any unique interests to perturb our thinking. The modern representative democracy was the best form of government mid-eighteenth century politicians technology could invent. The twenty-first century is a very different place technically, scientifically, and philosophically. What could democracy look like if it were reinvented today? Would it even be democracy­—what comes after democracy?

Some questions to think about:

  • Representative democracies were built under the assumption that travel and communications were difficult. Does it still make sense to organize our representative units by geography? Or to send representatives far away to create laws in our name? Is there a better way for people to choose collective representatives?
  • Indeed, the very idea of representative government is due to technological limitations. If an AI system could find the optimal solution for balancing every voter’s preferences, would it still make sense to have representatives­—or should we vote for ideas and goals instead?
  • With today’s technology, we can vote anywhere and any time. How should we organize the temporal pattern of voting—­and of other forms of participation?
  • Starting from scratch, what is today’s ideal government structure? Does it make sense to have a singular leader “in charge” of everything? How should we constrain power­—is there something better than the legislative/judicial/executive set of checks and balances?
  • The size of contemporary political units ranges from a few people in a room to vast nation-states and alliances. Within one country, what might the smaller units be­—and how do they relate to one another?
  • Who has a voice in the government? What does “citizen” mean? What about children? Animals? Future people (and animals)? Corporations? The land?
  • And much more: What about the justice system? Is the twelfth-century jury form still relevant? How do we define fairness? Limit financial and military power? Keep our system robust to psychological manipulation?

My perspective, of course, is security. I want to create a system that is resilient against hacking: one that can evolve as both technologies and threats evolve.

The format was one that I have used before. Forty-eight people meet over two days. There are four ninety-minute panels per day, with six people on each. Everyone speaks for ten minutes, and the rest of the time is devoted to questions and comments. Ten minutes means that no one gets bogged down in jargon or details. Long breaks between sessions and evening dinners allow people to talk more informally. The result is a very dense, idea-rich environment that I find extremely valuable. (See the first ten comments below for details of the conversations.)

It was amazing event. Everyone participated. Everyone was interesting. (Details of the event—emerging themes, notes from the speakers—are in the comments.) It’s a week later and I am still buzzing with ideas. I hope this is only the first of an ongoing series of similar workshops.

A Digital Red Cross

The International Committee of the Red Cross wants some digital equivalent to the iconic red cross, to alert would-be hackers that they are accessing a medical network.

The emblem wouldn’t provide technical cybersecurity protection to hospitals, Red Cross infrastructure or other medical providers, but it would signal to hackers that a cyberattack on those protected networks during an armed conflict would violate international humanitarian law, experts say, Tilman Rodenhäuser, a legal adviser to the International Committee of the Red Cross, said at a panel discussion hosted by the organization on Thursday.

I can think of all sorts of problems with this idea and many reasons why it won’t work, but those also apply to the physical red cross on buildings, vehicles, and people’s clothing. So let’s try it.

NSA on Supply Chain Security

The NSA (together with CISA) has published a long report on supply-chain security: “Securing the Software Supply Chain: Recommended Practices Guide for Suppliers.“:

Prevention is often seen as the responsibility of the software developer, as they are required to securely develop and deliver code, verify third party components, and harden the build environment. But the supplier also holds a critical responsibility in ensuring the security and integrity of our software. After all, the software vendor is responsible for liaising between the customer and software developer. It is through this relationship that additional security features can be applied via contractual agreements, software releases and updates, notifications and mitigations of vulnerabilities.

Software suppliers will find guidance from NSA and our partners on preparing organizations by defining software security checks, protecting software, producing well-secured software, and responding to vulnerabilities on a continuous basis. Until all stakeholders seek to mitigate concerns specific to their area of responsibility, the software supply chain cycle will be vulnerable and at risk for potential compromise.

They previously published “Securing the Software Supply Chain: Recommended Practices Guide for Developers.” And they plan on publishing one focused on customers.

EDITED TO ADD (11/14): The proposed EU Cyber Resilience Act places obligations on software providers to deliver secure code, and fix bugs in a timely manner.
