Problems solved by technology

[0003] However, the EAP-AKA protocol has the following loopholes and deficiencies: the authentication process requires multiple requests and corresponding interactions, which causes a large delay in authentication. When UE (user equipment) is continuously switched between different wireless LANs, These delays will become a bottleneck; cipher suite negotiation and authentication protocol version negotiation are not supported; encryption keys and encryption and decryption algorithms are fixed

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The idea of ​​WEAP not only keeps the access authentication protocol WAPI mechanism in the WAPI security protocol unchanged, but also ensures that the UE can safely access the 4G network through the WAPI AN. WAI certificate authentication uses two-way authentication. When the authentication requester UE (for equipment) requests authentication from the authentication server MME through the WLAN hotspot AP (access point), the AP decides to access the netwo...

Abstract

The invention discloses an enhanced EAP identity verification method for a power wireless private network, and the method comprises the steps: sending an authentication activation request from an AP to UE until the AP and the UE receive a certificate authentication result of an MME and determine whether to open a controlled port, and enabling the UE and the AP to complete unicast key negotiation and generate a negotiated session key. According to the invention, not only is the access authentication protocol WAPI mechanism in the WAPI security protocol kept unchanged, but also the UE can be ensured to safely access the 4G network through the WAPI AN.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an enhanced EAP authentication method for electric power wireless private network. Background technique [0002] At present, the State Grid Corporation of China is vigorously promoting the construction of the electric power wireless private network test network. In the construction process of electric power wireless private network, TD-LTE (Time Division Long Term Evolution) communication technology with high speed, large capacity and high spectrum efficiency has become a research hotspot in the construction of electric power wireless private network. LTE is the latest mobile communication standard proposed by the Third Generation Partnership Project (3GPP) under the background of 4G. The power wireless private network has high requirements on network performance and service quality, so in some cases it is not enough to use only LTE. LTE's network arc...
