Rijndael (AES) is a symmetric block cipher. Why WPA2 uses symmetric cryptography in a communication (which is an asymmetric situation)?
In what way do you mean it is asymmetric? CCMP can be used with preshared keys. Even if authentication were using asymmetric algorithms, have you looked at any real-world crypto protocols that use public keys for authentication? They pretty much all use symmetric ciphers for encryption after agreeing on a session key, so this isn't unusual. As another poster mentioned, the primary reason for this is performance. tim _______________________________________________ Full-Disclosure - We believe in it.
