Problems solved by technology

However, SSL VPN technology implements identity authentication between the server and the device based on an asymmetric encryption algorithm. With the improvement of computer computing power, the asymmetric encryption algorithm can be cracked, resulting in low security of identity authentication between the server and the device.

Abstract

The invention provides a method, device and system for identity authentication. A quantum authentication server receives a first authentication request sent by a VPN network device, uses a first quantum key to encrypt to obtain a first ciphertext, and returns an authentication response to the VPN network device. The VPN network device uses the first quantum key to decrypt the first ciphertext in the authentication response, obtains the first check code, and generates the second check code. When the first check code and the second check code are the same, the quantum The identity authentication of the authentication server is passed. The VPN network device uses the second quantum key to encrypt to obtain the second ciphertext, and sends the second authentication request to the quantum authentication server. The quantum authentication server decrypts the second ciphertext in the second authentication request, obtains the third check code, and generates the fourth check code. When the third check code is the same as the fourth check code, the identity of the VPN network device Certification passed. In the above identity authentication process, a quantum key is used for encryption, which improves the security of identity authentication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an identity authentication method, device and system. Background technique [0002] With the development of Internet technology and communication technology, the network transmission of business data can be realized through the Internet, and the timeliness of business response can be improved. In order to prevent data from being intercepted or tampered with by illegal devices when data is transmitted on the Internet, the server needs to authenticate the device requesting communication, and the device also needs to authenticate the server. [0003] At present, SSL VPN (Secure Sockets Layer, Virtual Private Network, Secure Sockets Layer Virtual Private Network) technology is used to construct a secure data transmission network. However, SSL VPN technology implements identity authentication between the server and the device based on an asymmetric encryption algorithm...
