Impossible plaintext cryptanalysis and probable-plaintext collision attacks of 64-bit block cipher modes
... Arguably, the vulnerabilities exploited in this work are more rel- evant to security practice than differential, linear, integral, algebraic, and biclique cryptanalysis. The biclique attack on AES with 128-bit keys, for ...

The Vulnerability of SSL to Chosen Plaintext Attack
... Third, the adversary must know the value of the IV that is going to be used for the next message. However, we have noted already that because of the way SSL computes IVs, an attacker would actually obtain this ...
