AES vs RC4 vs TKIP

I beleive out of the three (AES RC4 and TKIP) two are same type i.e, AES and RC4 but TKIP is not the same as AES or RC4

1 Can someone explain me the differnce between the three


2 Does AES use RC4 as its cipher algorithm or it itself is a cipher algorithm.

AES and RC4 are both encyption ciphers. They work differently in that AES is a block cipher while RC4 is a stream cipher. TKIP isn't a cipher like the other 2, but rather a protocol for implementing the RC4 cipher, similar to how WEP is an encryption implementation (that also uses RC4). However TKIP uses RC4 in a different way than WEP does.

For more info on AES and RC4, wikipedia actually has a really good pages. If you want more comprehensive material (as well as extensive introductory material), I would strongly recommend reading Applied Cryptography by Bruce Schneier.

Capt_Caveman answered question 1. Answer to question 2 is also here, but may be not obvious. So, AES doesn't use RC4.

Like Capt Caveman said, Wikipedia has some great definitions for almost all methods. I would also recommend that you check out Triple DES too. DES3 is a little slower than AES but also very secure.
