Enhanced authentication for WLAN–EPS interworking systems

Novel authentication procedures for interworking wireless local area networks and evolved packet system are proposed for the 3GPP TS 33.402 (released 12 September 2014) standard. The novel solutions mainly exploit public-key fully homomorphic encryption schemes and one-way functions. This not only mitigates potential security threats, but significantly reduces the authentication load of the standard, especially in the case of 3GPP-IP access.
