Title: AUTHENTICATING A MESSAGE IN A WIRELESS COMMUNICATION SYSTEM
Abstract:
An authentication node (22) in a wireless communication system (10) authenticates a message received by a recipient radio node (16A) (e.g., a user equipment). The authentication node (22) in this regard determines a radio resource that carries the message received by the recipient radio node (16A). The authentication node (22) performs authentication of the message, by checking whether the message is bound to the determined radio resource. The authentication node (22) may, for example, compute an expected authentication or integrity code based on information identifying the determined radio resource and check whether the expected authentication or integrity code matches an authentication or integrity code associated with the message.
