第21题:
the two methods of authentication using the WEP encryption are open and shared key
the 802.11 standard defines WEP security using 128-bit keys
WEP can provide stronger authentication through the use of LEAP, PEAP, or EAP-FAST
WEP is a scalable encryption solution that uses static keys for authentication
WEP security provides only one-way authentication
WEPv2 offers improved encryption by replacing the RC4 encryption mechanism with the AES (symmetric block cipher) mechanism
