WEP Attacks
There are several problems with the security of WEP. In all fairness, it was never meant to be a strong cryptographic protocol, but rather a way to provide a wired equivalency, as alluded to by the acronym. Aside from the security weaknesses relating to association and identities, there are several problems with the cryptographic protocol itself. Some of these problems stem from the use of CRC32 as a checksum function for message integrity, and other problems stem from the way IVs are used.
Offline Brute-Force Attacks
Brute forcing will always be a possible attack on any computationally secure cryptosystem. The only question that remains is whether it's a practical attack or not. With WEP, the actual method of offline brute forcing is ...
