Cybersecurity for the Public Interest

The Crypto Wars have been waging off-and-on for a quarter-century. On one side is law enforcement, which wants to be able to break encryption, to access devices and communications of terrorists and criminals.

Cybersecurity for the Public Interest

The Crypto Wars have been waging off-and-on for a quarter-century. On one side is law enforcement, which wants to be able to break encryption, to access devices and communications of terrorists and criminals. On the other are almost every cryptographer and computer security expert, repeatedly explaining that there’s no way to provide this capability without also weakening the security of… Continue reading Cybersecurity for the Public Interest

Hacking the GCHQ Backdoor

Last week, I evaluated the security of a recent GCHQ backdoor proposal for communications systems. Furthering the debate, Nate Cardozo and Seth Schoen of EFF explain how this sort of backdoor can be detected: In fact, we think when the ghost feature is active­ — silently inserting a secret eavesdropping member into an otherwise end-to-end encrypted conversation in the manner… Continue reading Hacking the GCHQ Backdoor

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 UK, 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 eavesdropping. Sometimes… Continue reading Evaluating the GCHQ Exceptional Access Proposal

New Australian Backdoor Law

Last week, Australia passed a law giving the government the ability to demand backdoors in computers and communications systems. Details are still to be defined, but it’s really bad. Note: Many people e-mailed me to ask why I haven’t blogged this yet. One, I was busy with other things. And two, there’s nothing I can say that I haven’t said… Continue reading New Australian Backdoor Law

More on the Five Eyes Statement on Encryption and Backdoors

Earlier this month, I wrote about a statement by the Five Eyes countries about encryption and back doors. (Short summary: they like them.) One of the weird things about the statement is that it was clearly written from a law-enforcement perspective, though we normally think of the Five Eyes as a consortium of intelligence agencies. Susan Landau examines the details… Continue reading More on the Five Eyes Statement on Encryption and Backdoors

Ray Ozzie’s Encryption Backdoor

Last month, Wired published a long article about Ray Ozzie and his supposed new scheme for adding a backdoor in encrypted devices. It’s a weird article. It paints Ozzie’s proposal as something that "attains the impossible" and "satisfies bo… Continue reading Ray Ozzie’s Encryption Backdoor

Ray Ozzie’s Encryption Backdoor

Last month, Wired published a long article about Ray Ozzie and his supposed new scheme for adding a backdoor in encrypted devices. It’s a weird article. It paints Ozzie’s proposal as something that "attains the impossible" and "satisfies both law enforcement and privacy purists," when (1) it’s barely a proposal, and (2) it’s essentially the same key escrow scheme we’ve… Continue reading Ray Ozzie’s Encryption Backdoor
