Abstract: A user equipment (UE) establishes a unicast link with a second UE, including establishing an authentication and security establishment procedure between the first UE and the second UE. The UE establishes a security context with the second UE during the authentication and security establishment procedure. The UE starts a timer based on a status of the unicast link. The UE reestablishes the unicast link with the second UE using the security context when the unicast link is reestablished prior to expiration of the timer.

Abstract: A network node for anonymizing sensitive subscriber data in a communication network is described. The network node generates an anonymous subscriber identifier based on a subscriber identifier and an anchor key by a first stage of an iterative key derivation function comprising two stages. The network node transmits the anonymous subscriber identifier to a second network node. A further network node for applying the anonymized sensitive subscriber data to generate an authentication key is provided. The further network node receives an anonymous subscriber identifier generated by a first network node, and generates an authentication key based at least on the anonymous subscriber identifier and the anchor key by a second stage of the iterative key derivation function.
