Answer(s): B,C,D

Explanation:

The Advanced Encryption Standard (AES) is gaining acceptance as an appropriate replacement for the RC4 algorithm used in WEP. AES uses the Rijndale (pronounced 'RINE-dale') algorithm in the following specified key lengths:
128-bit
192-bit
256-bit
AES is considered to be un-crackable by most cryptographers, and the National Institute of Standards and Technology (NIST) has chosen AES for the Federal Information Processing Standard, or FIPS. As part of the effort to improve the 802.11 standard, the 802.11i working committee is considering the use of AES in WEPv2.
