Method, apparatus, and system for preventing abuse of authentication vector
A method for preventing abuse of an Authentication Vector (AV) and a system and apparatus for implementing the method are provided. Access network information of a non-3rd Generation Partnership Project (3GPP) access network where a user resides is bound to an AV of the user, so that when the user accesses an Evolved Packet System (EPS) through the non-3GPP access network, even if an entity in the non-3GPP access network is breached, or an Evolved Packet Data Gateway (ePDG) connected to an untrusted non-3GPP access network is breached, the stolen AV cannot be applied to other non-3GPP access networks by an attacker.
