A、the two methods of authentication using the WEP encryption are open and shared key

B、the 802.11 standard defines WEP security using 128-bit keys

C、WEP can provide stronger authentication through the use of LEAP， PEAP， or EAP-FAST

D、WEP is a scalable encryption solution that uses static keys for authentication

E、WEP security provides only one-way authentication

F、WEPv2 offers improved encryption by replacing the RC4 encryption mechanism with the AES （symmetric block cipher） mechanism
