Problems solved by technology

In the face of the foreseeable research and construction of quantum computers, cryptosystems based on computational complexity have security risks
Therefore, there are security risks in the current electronic signature system and electronic contract signing system based on PKI technology.
In order to cope with the security threat of its own defects, the length of the PKI key has been continuously increased, from the initial 512bit to 1024bit, and then increased to 2048bit, but its own security defects cannot be changed

Abstract

According to the electronic contract signing method and system based on the electronic signature, encryption is conducted through a symmetric key algorithm, the quantum attack resisting characteristic is achieved, the defect that the safety of a traditional electronic signature algorithm and an electronic contract signing method based on PKI is based on calculation safety is fundamentally overcome, implementation is achieved based on a quantum cryptography network, and the safety of the electronic contract signing method is improved. One-time pad encryption is realized by adopting a method of labeling a used key, and unconditional security is achieved; the electronic signature information of the signing party is embedded in the signing of the electronic contract, so that the electronic contract has double credibility, and the signing reliability of the electronic contract is improved.

Description

technical field [0001] The invention belongs to the technical field of encrypted communication of quantum cryptography networks, and in particular relates to an electronic contract signing method and system based on electronic signatures. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Electronic signatures generally refer to all existing electronic codes attached to electronic documents, which can identify the identity of the signer of the electronic document, ensure the integrity of the document, and indicate that the signer agrees with the content of the matters stated in the electronic document. [0004] The electronic signature system is a high-tech emerging along with the information construction. It mainly solves the problem of signing and sealing electronic documents, and is used to identify the identity of the signer of electroni...
