Problems solved by technology

[0006] (1) Since the quantum computer can quickly obtain the corresponding private key through the public key, the existing HTTPS communication method based on the public and private key is easily cracked by the quantum computer
[0007] (2) In the existing technology, the input and output of digital signatures based on public and private keys can be known by the enemy. In the case of the existence of quantum computers, the private key may be derived, resulting in a public-private key-based HTTPS communication system cracked by quantum computer

Abstract

The invention discloses an antiquantum computing HTTPS communication method and system based on an asymmetric key pool, and the method comprises the following steps carried out at a server end: obtaining a digital certificate issued by a certificate authorization center, sending the digital certificate to a client, and recording a public key pointer random number of a server in the digital certificate. The method is carried out at a client and comprises the following steps of: obtaining a root digital certificate which is issued by a certificate authorization center and is matched with the digital certificate; verifying a digital certificate sent by the server according to the root digital certificate; obtaining a server public key from the asymmetric key pool according to a public key pointer random number of the server recorded in the verified digital certificate; encrypting a randomly generated shared key by using the public key of the server, and sending an encryption result to theserver to perform key negotiation; and performing HTTPS communication with the server by using the shared key. The security of communication is improved, and the communication is prevented from beingcracked by a quantum computer.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to an anti-quantum computing HTTPS communication method and system based on an asymmetric key pool. Background technique [0002] HTTPS refers to the Secure Socket Layer Hypertext Transfer Protocol, which is used to solve the defects of HTTP protocol plaintext transmission information. For the security of data transmission, HTTPS adds the SSL protocol on the basis of HTTP. SSL relies on certificates to verify the identity of the server and encrypt the communication between the browser and the server. The HTTPS protocol needs to apply for a certificate from the CA to prove the type of server usage. The certificate contains a pair of public and private keys, and the client only trusts the host when the certificate is used for the corresponding server. All communication between server and client is encrypted. [0003] At present, traditional communication encryption and transmiss...
