Method for establishing a security channel data of tunnel.

摘要

Abstract invention patent: method for establishing a security channel data of the tunnel. " The methods of this invention provide a method for establishing a data channel tunnel safety S2C, a device authentication and a device for door.The method includes: sending a request message authentication to an authentication device, receiving a response message to the authentication sent by the authentication device, in which the response message to the authentication includes an element of information of rela Reliable tion that is used to indicate a trust relationship from a current access.And the establishment of the association of safety of the tunnel S2C according to the trust relationship of access today.According to the method of this invention, when a UE accesses a network of EPS from one side of the non 3GPP access through an S2C interface, the response message sent by the device authentication authentication is received and the channel tunnel safety data S2 C is established according to the relationship of trusted access current indicated in the response message.So that the reliable when the side of the access non 3GPP accesses the network of EPS can be obtained, thereby ensuring the establishment of a data channel tunnel safety S2C correct. 20423535v1
