LIGHTWEIGHT AUTHENTICATION FRAMEWORK FOR INTER-NETWORK HAND-OVER COORDINATION IN UNTRUSTWORTHY HETEROGENEOUS NETWORK EN-VIRONMENTS

摘要

An entity of a first communication network is provided. The entity comprises a verification means and an entity authentication credential. The verification means is provided for verifying at least one message originating from an UE (User Equipment) of the first communication network which is connected with a second communication network. The verifications means compares a message authentication credential element which is contained in the message with the entity authentication credential. The entity discards the message if the comparison results in a mismatch.
