NVD Damage Continued
There is something about having your product installed in over twenty billion instances all over the world and even out of the globe. In my case it helps me remain focused on and committed to working on the security aspects of curl. Ideally, we will never have our heartbleed moment. Security is also a generally ……
EFF to Court: Lifetime GPS Tracking Violates the Fourth Amendment
All too often, new police surveillance tools are initially applied to only the “worst of the worst” and then slowly—but surely—expanded to include an ever-growing number of less culpable individuals.

Users Betrayed as Australia Adopts a Copyright Censorship Regime

A shallow survey of formal methods for C code
Two interesting things in formally verified software happened recently. The big one was the release of SeL4 - a formally verified L4 microkernel. The second was much smaller, but closer to my usual scope: a paper which showed the correctness of sections of a couple of the assembly implementations of Curve25519.
AEADs: getting better at symmetric cryptography
I gave a talk a couple of weeks ago at the Yahoo Unconference . The conference was at the end of a particually hard week for a bunch of reasons and I fear that the talk wasn't that great.

This post is intended to disprove this myth that has been so carefully crafted by Facebook/WhatsApp marketing…
U.S. border surveillance towers have always been broken
A new bombshell scoop from NBC News revealed an internal U.S. Border Patrol memo claiming that 30 percent of camera towers that compose the agency's "Remote Video Surveillance System" (RVSS) program are broken. Except, this isn't a bombshell. What should actually be shocking is that Congressional leaders are acting…
The dark side of account bans
I recently lost my Facebook account for two months, and was significantly cut off from certain aspects of society during that time. This is the dark side of account bans.
