We’ve long known that 64 bits is too small for a block cipher these days. That’s why new block ciphers like AES have 128-bit, or larger, block sizes. The insecurity of the smaller block is nicely illustrated by a new attack called “Sweet32.” It exploits the ability to find block collisions in Internet protocols to … Read More “Collision Attacks Against 64-Bit Block Ciphers” »

I missed this paper when it was first published in 2012: “Neuroscience Meets Cryptography: Designing Crypto Primitives Secure Against Rubber Hose Attacks” Abstract: Cryptographic systems often rely on the secrecy of cryptographic keys given to users. Many schemes, however, cannot resist coercion attacks where the user is forcibly asked by an attacker to reveal the … Read More “Subconscious Keys” »
