Quantum computing resisted signature method and system based on asymmetric secret key pool

Abstract

The invention discloses a quantum computing resisted signature method and system based on an asymmetric secret key pool. The signature method comprises a secret key card which stores an electronic stamp and a group key pool is pre-issued, and a secret key card for signature and signature verification is configured with the same group key pool; during signature, the electronic stamp in the secret key card is used to sign a file, and the file with an electronic signature is generated; the electronic signature at least comprises a stamping signature generated via a stamp public key and a quantumcomputing resisted public key generated via the stamp public key together with the group secret key pool in the secret key card; and during signature verification, the group key pool extracts the stamp public key from the quantum computing resisted public key, and the stamp signature is verified by using the stamp public key.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to a signature method and a signature system using a key card to realize anti-quantum computing. Background technique [0002] Electronic seal, also called digital seal, is a visual representation of digital signature. It can also be understood as the electronicization of traditional seal and handwritten signature. Its function is similar to that of traditional seal or handwritten signature used on paper documents. . The objects that need to be affixed with electronic seals are electronic documents, and these electronic documents are also transmitted in the network environment, which makes the application system of electronic seals relatively complicated. Therefore, an electronic seal is not equivalent to a simple electronic seal picture, it must have three basic features such as ease of use, security, and scalability. [0003] The electronic seal system is mainly used to ensur...

Problems solved by technology

[0007] 1. In the prior art, since the quantum computer can quickly obtain the corresponding private key through the public key, the digital signature method based on the public and private key is cracked by the quantum computer, and the electronic seal based on the digital signature technology is also cracked by the quantum computer

[0008] 2. In the existing technology, the input and output of digital signatures based on public and private keys can be known by others. In the presence of quantum computers, the private key may be deduced, resulting in electronic seals being cracked by quantum computers
