Researchers have demonstrated using Intel’s Software Guard Extensions to hide malware and steal cryptographic keys from inside SGX’s protected enclave: Malware Guard Extension: Using SGX to Conceal Cache Attacks Abstract:In modern computer systems, user processes are isolated from each other by the operating system and the hardware. Additionally, in a cloud scenario it is crucial … Read More “Using Intel's SGX to Attack Itself” »

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” »
