Submission + - 17% Smaller DES S-box Circuits Found ( 2

solardiz writes: "DES is still in use, brute-force key search remains the most effective attack on it, and it is an attractive building block for certain applications (the key size may be increased e.g. with 3DES). Openwall researchers, with funding from Rapid7, came up with 17% shorter Boolean expressions representing the DES S-boxes. Openwall's John the Ripper 1.7.8 tests over 20 million of combinations against DES-based crypt(3) per second on Core i7-2600K 3.4 GHz, which roughly corresponds to DES encryption speed of 33 Gbps."

Some people have a great ambition: to build something that will last, at least until they've finished building it.
