dynamic WEP
The IEEE introduced the
concept of user-based authentication using per-user encryption keys to solve the scalability
issues that surrounded static WEP. This resulted in the 802.1x standard, which makes use of
the IETF's Extensible Authentication Protocol (EAP), which was originally designed for user
authentication in dial-up networks. The 802.1x standard supplemented the EAP protocol with a
mechanism to send an encryption key to a Wireless AP. These encryption keys are used as
dynamic WEP keys, allowing traffic to each individual user to be encrypted using a separate
key.
