There’s No Good Reason to Trust Blockchain Technology
In his 2008 white paper that first proposed bitcoin, the anonymous Satoshi Nakamoto concluded with: “We have proposed a system for electronic transactions without relying on trust.” He was referring to blockchain, the system behind bitcoin cryptocurrency. The circumvention of trust is a great promise, but it’s just not true. Yes, bitcoin eliminates certain trusted intermediaries that are inherent in other payment systems like credit cards. But you still have to trust bitcoin—and everything about it.
Much has been written about …
The Public-Interest Technologist Track at the RSA Conference
Our work in cybersecurity is inexorably intertwined with public policy and—more generally—the public interest. It’s obvious in the debates on encryption and vulnerability disclosure, but it’s also part of the policy discussions about the Internet of Things, cryptocurrencies, artificial intelligence, social media platforms, and pretty much everything else related to IT.
This societal dimension to our traditionally technical area is bringing with it a need for public-interest technologists.
Defining this term is difficult. One blog post described public-interest technologists as “technology practitioners who focus on social justice, the common good, and/or the public interest.” A group of academics in this field wrote that “public-interest technology refers to the study and application of technology expertise to advance the public interest/generate public benefits/promote the public good.”…
Defending Democratic Mechanisms and Institutions against Information Attacks
To better understand influence attacks, we proposed an approach that models democracy itself as an information system and explains how democracies are vulnerable to certain forms of information attacks that autocracies naturally resist. Our model combines ideas from both international security and computer security, avoiding the limitations of both in explaining how influence attacks may damage democracy as a whole.
Our initial account is necessarily limited. Building a truly comprehensive understanding of democracy as an information system will be a Herculean labor, involving the collective endeavors of political scientists and theorists, computer scientists, scholars of complexity, and others…
Evaluating the GCHQ Exceptional Access Proposal
The so-called Crypto Wars have been going on for 25 years now. Basically, the FBI—and some of their peer agencies in the U.K., Australia, and elsewhere—argue that the pervasive use of civilian encryption is hampering their ability to solve crimes and that they need the tech companies to make their systems susceptible to government eavesdroping. Sometimes their complaint is about communications systems, like voice or messaging apps. Sometimes it’s about end-user devices. On the other side of this debate is pretty much all technologists working in computer security and cryptography, who …
The Most Damaging Election Disinformation Campaign Came From Donald Trump, Not Russia
On November 4, 2016, the hacker "Guccifer 2.0," a front for Russia’s military intelligence service, claimed in a blogpost that the Democrats were likely to use vulnerabilities to hack the presidential elections. On November 9, 2018, President Donald Trump started tweeting about the senatorial elections in Florida and Arizona. Without any evidence whatsoever, he said that Democrats were trying to steal the election through "FRAUD."
Cybersecurity experts would say that posts like Guccifer 2.0’s are intended to undermine public confidence in voting: a cyber-attack against the US democratic system. Yet Donald Trump’s actions are doing far more damage to democracy. So far, his tweets on the topic have been retweeted over 270,000 times, eroding confidence far more effectively than any foreign influence campaign…
Surveillance Kills Freedom By Killing Experimentation
Excerpted from the upcoming issue of McSweeney’s, “The End of Trust,” a collection featuring more than 30 writers investigating surveillance, technology, and privacy.
In my book Data and Goliath, I write about the value of privacy. I talk about how it is essential for political liberty and justice, and for commercial fairness and equality. I talk about how it increases personal freedom and individual autonomy, and how the lack of it makes us all less secure. But this is probably the most important argument as to why society as a whole must protect privacy: it allows society to progress…
Information Attacks on Democracies
Democracy is an information system.
That’s the starting place of our new paper: “Common-Knowledge Attacks on Democracy.” In it, we look at democracy through the lens of information security, trying to understand the current waves of Internet disinformation attacks. Specifically, we wanted to explain why the same disinformation campaigns that act as a stabilizing influence in Russia are destabilizing in the United States.
The answer revolves around the different ways autocracies and democracies work as information systems. We start by differentiating between two types of knowledge that societies use in their political systems. The first is …
We Need Stronger Cybersecurity Laws for the Internet of Things
Due to ever-evolving technological advances, manufacturers are connecting consumer goods—from toys to lightbulbs to major appliances—to the internet at breakneck speeds. This is the Internet of Things, and it’s a security nightmare.
The Internet of Things fuses products with communications technology to make daily life more effortless. Think Amazon’s Alexa, which not only answers questions and plays music but allows you to control your home’s lights and thermostat. Or the current generation of implanted pacemakers, which can both receive commands and send information to doctors over the internet…
Nobody’s Cellphone Is Really That Secure
But most of us aren’t the president of the United States.
Earlier this week, The New York Times reported that the Russians and the Chinese were eavesdropping on President Donald Trump’s personal cellphone and using the information gleaned to better influence his behavior. This should surprise no one. Security experts have been talking about the potential security vulnerabilities in Trump’s cellphone use since he became president. And President Barack Obama bristled at—but acquiesced to—the security rules prohibiting him from using a “regular” cellphone throughout his presidency.
Three broader questions obviously emerge from the story. Who else is listening in on Trump’s cellphone calls? What about the cellphones of other world leaders and senior government officials? And—most personal of all—what about …
