Method for batch handover authentication and key agreement oriented to heterogeneous network

A method for a batch handover authentication and a key agreement oriented to a heterogeneous network, comprising the following steps:

• S1, system establishment and participant registration:
• establishing a system, and allowing users authenticated by a plurality of participants to register on a long term evolution-advanced (LTE-A) network to obtain identity information of the users, respectively;
• S2, access authentication:
• taking an equipment with a computing capacity superior to a storage capacity as a leader, discovering a target access network WLAN by using a discovery function module ADNSF, sending, by the leader, complete group authentication information to an authentication, authorization, and accounting (AAA) server of the target access network WLAN to authenticate identity information of the plurality of participants, determining whether the identity information of the plurality of participants is successfully authenticated, if the identity information of the plurality of participants is successfully authenticated, returning an identity authentication response by the AAA server of the target access network WLAN to complete the batch handover authentication and the key agreement, and if the identity information of the plurality of participants is not successfully authenticated, entering step S3;
• and
• S3, if the identity information of the plurality of participants is not successfully authenticated, terminating an execution to complete the batch handover authentication and the key agreement.
