This was in the 10/28 issue of Network World Infusion. Did anyone else see it? Gurus prove that encryption's not all it's cracked up to be Two eminent Israeli cryptographers last week sent a shock wave through security circles with the announcement that they had figured out a way to extract private Data Encryption Standard (DES) encryption keys from such things as PCs and smart cards. Adi Shamir and Eli Biham showed they could get at even a Triple-DES secret key, by applying small amounts of heat or radiation to change the key's bit structure. Then, using a technique known as Differential Fault Analysis, they compared the encrypted outputs from both the damaged and undamaged cards to derive the key. ...
