Recovery from key compromise is why I wouldn't touch a system like this with a thousand foot pole. It is hairy, but it was the assumption we were given to work with. | |
Jan 28, 2013 at 12:48 | comment | added | Thomas | I think we can assume that IV's and counters will never feasibly repeat for a decent block size (128 or 256 bits), the only problem left being key compromise: how to recover if the key is leaked? do you lose backward and possibly forward secrecy? etc.. | |
