Identity authentication method and device

Abstract

The invention discloses an identity authentication method, a request device and an authentication access controller, when identity authentication is carried out based on an authentication mechanism of a pre-shared key, identity information of an authenticated party is transmitted in a ciphertext form, the identity information of the authenticated party is prevented from being directly exposed in a transmission process, and an attacker is ensured not to obtain private and sensitive information; according to the method, the confidentiality of entity identity related information is ensured, and bidirectional or unidirectional identity authentication between the access controller and the request equipment is realized, so that a foundation is laid for ensuring that a user accessing a network is legal and / or the network accessed by the user is legal. Meanwhile, in combination with key exchange calculation and through ingenious detail design, the ability of resisting dictionary brute force cracking or quantum computing attack in the identification process is enhanced.

Description

technical field [0001] The present application relates to the technical field of network communication security, and in particular, to an identity authentication method and device. Background technique [0002] In a communication network, a requesting device can access the network through an authenticated access controller. In some cases with high security requirements, the authentication access controller needs to authenticate the identity of the requesting device, and sometimes the requesting device also needs to authenticate the identity of the authentication access controller to ensure that the requesting device accessing the network belong to a legitimate user, and / or the network requesting access to the device belongs to a legitimate network. In addition, the point-to-point transmission in the blockchain technology also needs to establish a trust relationship between different nodes, so it is also very important for the identification of nodes. [0003] At present, t...

Problems solved by technology

[0004] If during the identity authentication process between the requesting device and the network, the identity information of the requesting device is intercepted by an attacker for illegal purposes, or the identity information of the network is intercepted by an attacker for illegal purposes, the authentication access controller, request Devices and networks pose a great security risk
