Abstract
A wireless transmit receive unit (WTRU) is configured to receive unciphered and ciphered messages. The unciphered messages include identity requests, authentication requests, non-access stratum (NAS) security mode commands and tracking area update responses. The ciphered messages may come from the NAS and a Radio Resource Controller (RRC). The messages are ciphered using security keys.
