Network security authentication method

Abstract

The invention discloses a network security authentication method. The method comprises the following steps: S1, establishing an IPSec communication system; S2, carrying out matrix-based key pre-distribution; and S3, establishing a secret sharing mechanism. The beneficial effects are as follows: the method is suitable for an IKEv2 initial exchange process improvement protocol in a wireless networkenvironment. The protocol has obvious performance advantages. The method can be applied to a wireless Internet network environment; in addition, a quick switching authentication method based on a neighbor graph and a pre-distribution method based on a matrix key are adopted, a rapid switching authentication scheme of the wireless Mesh network is provided, the problem of quick switching authentication failure caused by the mobility of the Mesh access point can be solved, through a self-healing group key distribution scheme, a safety channel does not need to be established between a group administrator and each group member to distribute personal secret information of the group members, and safety of storage overhead and communication overhead is achieved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a network security authentication method. Background technique [0002] A wireless network is a network communication system that uses wireless transmission media to interconnect multiple devices without a physical connection. It is the product of the combination of computer networks and wireless communication technologies. The combination of computer and wireless communication makes mobile become ubiquitous, and mobile terminals can access and access Internet resources anytime and anywhere through wireless networks. Future mobile terminals will be devices that integrate multiple wireless access methods, such as PDAs, handheld phones, and notebook computers that support IEEE802.11 series, 3G, and GPRS technologies. The application of wireless network expands the free space of network users, and has the advantages of convenient installation and flexible network structure...
