A multi-group e-commerce signature method based on quantum teleportation

Abstract

The invention belongs to the technical field of e-commerce information processing methods, and discloses a multi-group e-commerce signature method and system based on quantum teleportation. The multi-group e-commerce signature method based on quantum teleportation includes: the application of the first group The user sends purchase information to the second group; after blinding the purchase information of the applicant user to hide the identity information of the applicant user, it is sent to the first group review center; the first group review center receives the purchase information of the applicant user After that, the purchase information review is carried out; after the second group review center receives the information, it compares whether the payment information sent is correct. The present invention uses Bell state particles and single photons, and these particles are relatively easy to realize compared with other cluster states and multi-particle states; the present invention has a certain resistance to general interception and retransmission attacks and entanglement attacks At the same time, it has a certain degree of non-repudiation and non-forgeability.

Description

technical field [0001] The invention belongs to the technical field of e-commerce information processing methods, in particular to a multi-group e-commerce signature method based on quantum teleportation. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Since Diffie and Hellman proposed the first digital signature protocol, digital signatures have played a very critical role in classical cryptography and many other application scenarios such as data integrity protection, authentication, and authorization. However, the security of classical digital signatures depends on some unproven computational complexity assumptions, which are unreliable in the face of quantum computing. [0004] Due to the nature of quantum states, quantum signatures have attracted a lot of interest, and many quantum signature schemes have been proposed in recent years. The first quantum signature scheme was proposed by Gottesman...

AI Technical Summary

Problems solved by technology

[0009] (3) Most of the quantum signature protocols at this stage lack detailed analysis of the security of the protocol itself. text description, lack of analysis process for some specific attack strategies

[0013] The blinding process of many quantum signatures blindly uses the processing methods in the above problems, which has great security risks in terms of user privacy protection. This blinding process also needs to be improved urgently.
