Problems solved by technology
[0008] However, with the development of quantum computers, the classic asymmetric key encryption algorithm will no longer be safe. Regardless of encryption and decryption, digital signatures or key exchange methods, quantum computers can obtain private keys through public key calculations. Therefore, the current classic digital certificate will become vulnerable in the quantum age

The present invention relates to a quantum-resistant certificate acquisition method and acquisition system based on a public key pool. Participants include a certificate authority center and users. Each participant is equipped with a key card, and each key card stores a public key pool and a private key. unit, and the random number of the public key pointer of the certificate authority center, and the random number of the user’s public key pointer is also stored in the user’s key card. The key pointer random number and the request information of the user identity; use the signature private key to sign the request information; generate a true random number, use the true random number to encrypt the request information and signature, and obtain the first ciphertext; use the certificate authorization The encryption public key of the center encrypts the true random number to obtain the second ciphertext; sends the first ciphertext and the second ciphertext to the certificate authority; receives and verifies the authorization certificate of the certificate authority.
Description
technical field [0001] The invention relates to the field of secure communication, in particular to a quantum-resistant certificate acquisition system and acquisition method based on a public key pool. Background technique [0002] Digital signature (also known as public key digital signature, electronic signature, etc.) is conceptually similar to an ordinary physical signature written on paper, but it uses the technology in the field of public key encryption to identify digital information. A set of digital signatures usually defines two complementary operations, one for signing and the other for verification. [0003] A digital signature is a digital string that only the sender of the message can produce and cannot be forged by others. This digital string is also an effective proof of the authenticity of the message sent by the sender of the message. [0004] The document integrity of the digital signature is very easy to verify (doesn't need the seam seal, the seam signa...
