Which of the following BEST describes the weakness in WEP encryption?
The initialization vector of WEP uses a crack-able RC4 encryption algorithm. Once enough packets are
captured an XOR operation can be performed and the asymmetric keys can be derived.
The WEP key is stored in plain text and split in portions across 224 packets of random data. Once enough
packets are sniffed the IV portion of the packets can be removed leaving the plain text key.
The WEP key has a weak MD4 hashing algorithm used. A simple rainbow table can be used to generate
key possibilities due to MD4 collisions.
The WEP key is stored with a very small pool of random numbers to make the cipher text. As the random
numbers are often reused it becomes easy to derive the remaining WEP key.
WEP is based on RC4, but due to errors in design and implementation, WEP is weak in a number of areas, twoof which are the use of a static common key and poor implementation of initiation vectors (IVs). When the WEP
key is discovered, the attacker can join the network and then listen in on all other wireless client
