You Can’t Rush Post-Quantum-Computing Cryptography Standards

I just read an article complaining that NIST is taking too long in finalizing its post-quantum-computing cryptography standards.

This process has been going on since 2016, and since that time there has been a huge increase in quantum technology and an equally large increase in quantum understanding and interest. Yet seven years later, we have only four algorithms, although last week NIST announced that a number of other candidates are under consideration, a process that is expected to take “several years.

The delay in developing quantum-resistant algorithms is especially troubling given the time it will take to get those products to market. It generally takes four to six years with a new standard for a vendor to develop an ASIC to implement the standard, and it then takes time for the vendor to get the product validated, which seems to be taking a troubling amount of time.

Yes, the process will take several years, and you really don’t want to rush it. I wrote this last year:

Ian Cassels, British mathematician and World War II cryptanalyst, once said that “cryptography is a mixture of mathematics and muddle, and without the muddle the mathematics can be used against you.” This mixture is particularly difficult to achieve with public-key algorithms, which rely on the mathematics for their security in a way that symmetric algorithms do not. We got lucky with RSA and related algorithms: their mathematics hinge on the problem of factoring, which turned out to be robustly difficult. Post-quantum algorithms rely on other mathematical disciplines and problems­—code-based cryptography, hash-based cryptography, lattice-based cryptography, multivariate cryptography, and so on­—whose mathematics are both more complicated and less well-understood. We’re seeing these breaks because those core mathematical problems aren’t nearly as well-studied as factoring is.

[…]

As the new cryptanalytic results demonstrate, we’re still learning a lot about how to turn hard mathematical problems into public-key cryptosystems. We have too much math and an inability to add more muddle, and that results in algorithms that are vulnerable to advances in mathematics. More cryptanalytic results are coming, and more algorithms are going to be broken.

As to the long time it takes to get new encryption products to market, work on shortening it:

The moral is the need for cryptographic agility. It’s not enough to implement a single standard; it’s vital that our systems be able to easily swap in new algorithms when required.

Whatever NIST comes up with, expect that it will get broken sooner than we all want. It’s the nature of these trap-door functions we’re using for public-key cryptography.

New SEC Rules around Cybersecurity Incident Disclosures

The US Securities and Exchange Commission adopted final rules around the disclosure of cybersecurity incidents. There are two basic rules:

  1. Public companies must “disclose any cybersecurity incident they determine to be material” within four days, with potential delays if there is a national security risk.
  2. Public companies must “describe their processes, if any, for assessing, identifying, and managing material risks from cybersecurity threats” in their annual filings.

The rules go into effect this December.

In an email newsletter, Melissa Hathaway wrote:

Now that the rule is final, companies have approximately six months to one year to document and operationalize the policies and procedures for the identification and management of cybersecurity (information security/privacy) risks. Continuous assessment of the risk reduction activities should be elevated within an enterprise risk management framework and process. Good governance mechanisms delineate the accountability and responsibility for ensuring successful execution, while actionable, repeatable, meaningful, and time-dependent metrics or key performance indicators (KPI) should be used to reinforce realistic objectives and timelines. Management should assess the competency of the personnel responsible for implementing these policies and be ready to identify these people (by name) in their annual filing.

Commentary on the Implementation Plan for the 2023 US National Cybersecurity Strategy

The Atlantic Council released a detailed commentary on the White House’s new “Implementation Plan for the 2023 US National Cybersecurity Strategy.” Lots of interesting bits.

So far, at least three trends emerge:

First, the plan contains a (somewhat) more concrete list of actions than its parent strategy, with useful delineation of lead and supporting agencies, as well as timelines aplenty. By assigning each action a designated lead and timeline, and by including a new nominal section (6) focused entirely on assessing effectiveness and continued iteration, the ONCD suggests that this is not so much a standalone text as the framework for an annual, crucially iterative policy process. That many of the milestones are still hazy might be less important than the commitment. the administration has made to revisit this plan annually, allowing the ONCD team to leverage their unique combination of topical depth and budgetary review authority.

Second, there are clear wins. Open-source software (OSS) and support for energy-sector cybersecurity receive considerable focus, and there is a greater budgetary push on both technology modernization and cybersecurity research. But there are missed opportunities as well. Many of the strategy’s most difficult and revolutionary goals—­holding data stewards accountable through privacy legislation, finally implementing a working digital identity solution, patching gaps in regulatory frameworks for cloud risk, and implementing a regime for software cybersecurity liability—­have been pared down or omitted entirely. There is an unnerving absence of “incentive-shifting-focused” actions, one of the most significant overarching objectives from the initial strategy. This backpedaling may be the result of a new appreciation for a deadlocked Congress and the precarious present for the administrative state, but it falls short of the original strategy’s vision and risks making no progress against its most ambitious goals.

Third, many of the implementation plan’s goals have timelines stretching into 2025. The disruption of a transition, be it to a second term for the current administration or the first term of another, will be difficult to manage under the best of circumstances. This leaves still more of the boldest ideas in this plan in jeopardy and raises questions about how best to prioritize, or accelerate, among those listed here.

Paragon Solutions Spyware: Graphite

Paragon Solutions is yet another Israeli spyware company. Their product is called “Graphite,” and is a lot like NSO Group’s Pegasus. And Paragon is working with what seems to be US approval:

American approval, even if indirect, has been at the heart of Paragon’s strategy. The company sought a list of allied nations that the US wouldn’t object to seeing deploy Graphite. People with knowledge of the matter suggested 35 countries are on that list, though the exact nations involved could not be determined. Most were in the EU and some in Asia, the people said.

Remember when NSO Group was banned in the US a year and a half ago? The Drug Enforcement Agency uses Graphite.

We’re never going to reduce the power of these cyberweapons arms merchants by going after them one by one. We need to deal with the whole industry. And we’re not going to do it as long as the democracies of the world use their products as well.

Expeditionary Cyberspace Operations

Cyberspace operations now officially has a physical dimension, meaning that the United States has official military doctrine about cyberattacks that also involve an actual human gaining physical access to a piece of computing infrastructure.

A revised version of Joint Publication 3-12 Cyberspace Operations—published in December 2022 and while unclassified, is only available to those with DoD common access cards, according to a Joint Staff spokesperson—officially provides a definition for “expeditionary cyberspace operations,” which are “[c]yberspace operations that require the deployment of cyberspace forces within the physical domains.”

[…]

“Developing access to targets in or through cyberspace follows a process that can often take significant time. In some cases, remote access is not possible or preferable, and close proximity may be required, using expeditionary [cyber operations],” the joint publication states. “Such operations are key to addressing the challenge of closed networks and other systems that are virtually isolated. Expeditionary CO are often more regionally and tactically focused and can include units of the CMF or special operations forces … If direct access to the target is unavailable or undesired, sometimes a similar or partial effect can be created by indirect access using a related target that has higher-order effects on the desired target.”

[…]

“Allowing them to support [combatant commands] in this way permits faster adaptation to rapidly changing needs and allows threats that initially manifest only in one [area of responsibility] to be mitigated globally in near real time. Likewise, while synchronizing CO missions related to achieving [combatant commander] objectives, some cyberspace capabilities that support this activity may need to be forward-deployed; used in multiple AORs simultaneously; or, for speed in time-critical situations, made available via reachback,” it states. “This might involve augmentation or deployment of cyberspace capabilities to forces already forward or require expeditionary CO by deployment of a fully equipped team of personnel and capabilities.”

New National Cybersecurity Strategy

Last week, the Biden administration released a new National Cybersecurity Strategy (summary here). There is lots of good commentary out there. It’s basically a smart strategy, but the hard parts are always the implementation details. It’s one thing to say that we need to secure our cloud infrastructure, and another to detail what the means technically, who pays for it, and who verifies that it’s been done.

One of the provisions getting the most attention is a move to shift liability to software vendors, something I’ve been advocating for since at least 2003.

Banning TikTok

Congress is currently debating bills that would ban TikTok in the United States. We are here as technologists to tell you that this is a terrible idea and the side effects would be intolerable. Details matter. There are several ways Congress might ban TikTok, each with different efficacies and side effects. In the end, all the effective ones would destroy the free Internet as we know it.

There’s no doubt that TikTok and ByteDance, the company that owns it, are shady. They, like most large corporations in China, operate at the pleasure of the Chinese government. They collect extreme levels of information about users. But they’re not alone: Many apps you use do the same, including Facebook and Instagram, along with seemingly innocuous apps that have no need for the data. Your data is bought and sold by data brokers you’ve never heard of who have few scruples about where the data ends up. They have digital dossiers on most people in the United States.

If we want to address the real problem, we need to enact serious privacy laws, not security theater, to stop our data from being collected, analyzed, and sold—by anyone. Such laws would protect us in the long term, and not just from the app of the week. They would also prevent data breaches and ransomware attacks from spilling our data out into the digital underworld, including hacker message boards and chat servers, hostile state actors, and outside hacker groups. And, most importantly, they would be compatible with our bedrock values of free speech and commerce, which Congress’s current strategies are not.

At best, the TikTok ban considered by Congress would be ineffective; at worst, a ban would force us to either adopt China’s censorship technology or create our own equivalent. The simplest approach, advocated by some in Congress, would be to ban the TikTok app from the Apple and Google app stores. This would immediately stop new updates for current users and prevent new users from signing up. To be clear, this would not reach into phones and remove the app. Nor would it prevent Americans from installing TikTok on their phones; they would still be able to get it from sites outside of the United States. Android users have long been able to use alternative app repositories. Apple maintains a tighter control over what apps are allowed on its phones, so users would have to “jailbreak”—or manually remove restrictions from—their devices to install TikTok.

Even if app access were no longer an option, TikTok would still be available more broadly. It is currently, and would still be, accessible from browsers, whether on a phone or a laptop. As long as the TikTok website is hosted on servers outside of the United States, the ban would not affect browser access.

Alternatively, Congress might take a financial approach and ban US companies from doing business with ByteDance. Then-President Donald Trump tried this in 2020, but it was blocked by the courts and rescinded by President Joe Biden a year later. This would shut off access to TikTok in app stores and also cut ByteDance off from the resources it needs to run TikTok. US cloud-computing and content-distribution networks would no longer distribute TikTok videos, collect user data, or run analytics. US advertisers—and this is critical—could no longer fork over dollars to ByteDance in the hopes of getting a few seconds of a user’s attention. TikTok, for all practical purposes, would cease to be a business in the United States.

But Americans would still be able to access TikTok through the loopholes discussed above. And they will: TikTok is one of the most popular apps ever made; about 70% of young people use it. There would be enormous demand for workarounds. ByteDance could choose to move its US-centric services right over the border to Canada, still within reach of American users. Videos would load slightly slower, but for today’s TikTok users, it would probably be acceptable. Without US advertisers ByteDance wouldn’t make much money, but it has operated at a loss for many years, so this wouldn’t be its death knell.

Finally, an even more restrictive approach Congress might take is actually the most dangerous: dangerous to Americans, not to TikTok. Congress might ban the use of TikTok by anyone in the United States. The Trump executive order would likely have had this effect, were it allowed to take effect. It required that US companies not engage in any sort of transaction with TikTok and prohibited circumventing the ban. . If the same restrictions were enacted by Congress instead, such a policy would leave business or technical implementation details to US companies, enforced through a variety of law enforcement agencies.

This would be an enormous change in how the Internet works in the United States. Unlike authoritarian states such as China, the US has a free, uncensored Internet. We have no technical ability to ban sites the government doesn’t like. Ironically, a blanket ban on the use of TikTok would necessitate a national firewall, like the one China currently has, to spy on and censor Americans’ access to the Internet. Or, at the least, authoritarian government powers like India’s, which could force Internet service providers to censor Internet traffic. Worse still, the main vendors of this censorship technology are in those authoritarian states. China, for example, sells its firewall technology to other censorship-loving autocracies such as Iran and Cuba.

All of these proposed solutions raise constitutional issues as well. The First Amendment protects speech and assembly. For example, the recently introduced Buck-Hawley bill, which instructs the president to use emergency powers to ban TikTok, might threaten separation of powers and may be relying on the same mechanisms used by Trump and stopped by the court. (Those specific emergency powers, provided by the International Emergency Economic Powers Act, have a specific exemption for communications services.) And individual states trying to beat Congress to the punch in regulating TikTok or social media generally might violate the Constitution’s Commerce Clause—which restricts individual states from regulating interstate commerce—in doing so.

Right now, there’s nothing to stop Americans’ data from ending up overseas. We’ve seen plenty of instances—from Zoom to Clubhouse to others—where data about Americans collected by US companies ends up in China, not by accident but because of how those companies managed their data. And the Chinese government regularly steals data from US organizations for its own use: Equifax, Marriott Hotels, and the Office of Personnel Management are examples.

If we want to get serious about protecting national security, we have to get serious about data privacy. Today, data surveillance is the business model of the Internet. Our personal lives have turned into data; it’s not possible to block it at our national borders. Our data has no nationality, no cost to copy, and, currently, little legal protection. Like water, it finds every crack and flows to every low place. TikTok won’t be the last app or service from abroad that becomes popular, and it is distressingly ordinary in terms of how much it spies on us. Personal privacy is now a matter of national security. That needs to be part of any debate about banning TikTok.

Passwords Are Terrible (Surprising No One)

This is the result of a security audit:

More than a fifth of the passwords protecting network accounts at the US Department of the Interior—including Password1234, Password1234!, and ChangeItN0w!—were weak enough to be cracked using standard methods, a recently published security audit of the agency found.

[…]

The results weren’t encouraging. In all, the auditors cracked 18,174—or 21 percent—­of the 85,944 cryptographic hashes they tested; 288 of the affected accounts had elevated privileges, and 362 of them belonged to senior government employees. In the first 90 minutes of testing, auditors cracked the hashes for 16 percent of the department’s user accounts.

The audit uncovered another security weakness—the failure to consistently implement multi-factor authentication (MFA). The failure extended to 25—­or 89 percent—­of 28 high-value assets (HVAs), which, when breached, have the potential to severely impact agency operations.

Original story:

To make their point, the watchdog spent less than $15,000 on building a password-cracking rig—a setup of a high-performance computer or several chained together ­- with the computing power designed to take on complex mathematical tasks, like recovering hashed passwords. Within the first 90 minutes, the watchdog was able to recover nearly 14,000 employee passwords, or about 16% of all department accounts, including passwords like ‘Polar_bear65’ and ‘Nationalparks2014!’.

NIST Is Updating Its Cybersecurity Framework

NIST is planning a significant update of its Cybersecurity Framework. At this point, it’s asking for feedback and comments to its concept paper.

  1. Do the proposed changes reflect the current cybersecurity landscape (standards, risks, and technologies)?
  2. Are the proposed changes sufficient and appropriate? Are there other elements that should be considered under each area?
  3. Do the proposed changes support different use cases in various sectors, types, and sizes of organizations (and with varied capabilities, resources, and technologies)?
  4. Are there additional changes not covered here that should be considered?
  5. For those using CSF 1.1, would the proposed changes affect continued adoption of the Framework, and how so?
  6. For those not using the Framework, would the proposed changes affect the potential use of the Framework?

The NIST Cybersecurity Framework has turned out to be an excellent resource. If you use it at all, please help with version 2.0.

EDITED TO ADD (2/14): Details on progress and how to engage.

US Cyber Command Operations During the 2022 Midterm Elections

The head of both US Cyber Command and the NSA, Gen. Paul Nakasone, broadly discussed that first organization’s offensive cyber operations during the runup to the 2022 midterm elections. He didn’t name names, of course:

We did conduct operations persistently to make sure that our foreign adversaries couldn’t utilize infrastructure to impact us,” said Nakasone. “We understood how foreign adversaries utilize infrastructure throughout the world. We had that mapped pretty well. And we wanted to make sure that we took it down at key times.”

Nakasone noted that Cybercom’s national mission force, aided by NSA, followed a “campaign plan” to deprive the hackers of their tools and networks. “Rest assured,” he said. “We were doing operations well before the midterms began, and we were doing operations likely on the day of the midterms.” And they continued until the elections were certified, he said.

We know Cybercom did similar things in 2018 and 2020, and presumably will again in two years.
