Abstract
Provided are a method, a corresponding apparatus and a computer program product for performing a group authentication and key agreement procedure. A method comprises initiating, by a master device in a group of devices, a group authentication and key agreement procedure towards an authentication entity, wherein a shared group key is defined for use in the group authentication and key agreement procedure; performing mutual authentication between the master device and the authentication entity based upon the shared group key; and performing mutual authentication between the authenticated master device and other devices in the group based upon the shared group key for completion of the group authentication and key agreement procedure. With the claimed invention, the impact of the signaling overhead on a network can be significantly decreased without substantive modification to the existing architecture of the network.
