Abstract
A system and method for authentication of a secure element cooperating with a Mobile Equipment forming a terminal in a telecommunication network is provided. The telecommunication network comprises a SEAF and a AUSF/UDM/ARPF. The method includes generating an anchor key (KSEAF_SRT) for the communication between the terminal and the SEAF according to 3GPP TS 33.501, wherein the anchor key (KSEAF_SRT) is indirectly derived from a key (KSRT) obtained by deriving from the long-term key K and a secure registration token SRT sent by the terminal to the AUSF/UDM/ARPF and concealed with the AUSF/UDM/ARPF public key along with its SUPI in the SUCI. Other embodiments are disclosed.
