Abstract  Abstract

The present invention relates to a solution for handling security issues of non access stratum (NAS) signaling in a telecommunications network (100) The NAS signaling is performed between a user equipment (UE) and a mobility management node e.g.a mobility management entity (MME) The solution is realized in a device and in a method comprising steps of receiving an initial non access stratum message from the UE (101) communicating wirelessly (105) with the telecommunications network determining security context status for the UE determining if un-ciphered mode is to be used in the security context set ciphering algorithm to a null ciphering algorithm transmitting a security context and activation message to the UE comprising information indicating ciphering algorithm and receiving a security context activation acknowledge message from the UE.
