Encrypted blind signature method based on quantum secret communication technology

Abstract

The invention discloses an encrypted blind signature method based on a quantum secret communication technology. According to the method, the encrypted blind signature function is obfuscated by adopting an obfuscation technology, so that the code of the code obtained by reverse engineering of an enemy is an obfuscated code, the blindness and the one-mcore unforgeability under the encrypted blind signature obfuscator are proposed, and a source program is prevented from being obtained by a user or an unauthorized user. Then, in the protocol interaction process, a cooperation mode of a quantum keygeneration device and an encryption device is adopted, and the transmission security is ensured through a quantum key security distribution system of the quantum key generation device.

Description

technical field [0001] The invention relates to an encryption blind signature method, in particular to an encryption blind signature method based on quantum secret communication technology. Background technique [0002] Digital signature is one of the main application directions of cryptographic algorithms, and it is an information security technology with message authentication, identity authentication, integrity authentication and encryption. With the in-depth application of signature technology in military, communication, e-commerce and other fields, ordinary digital signature can no longer meet people's special needs, so the special digital signature technology blind signature used to protect user privacy was proposed. The difference between it and the usual digital signature is that the user can obtain a valid signature without letting the signer know the signed message and any information related to the signed message, even if the signer obtains the signature later , ...

Problems solved by technology

[0005] However, at present, quantum security communication technology is facing a series of problems in the process of marketization. One is the problems existing in the quantum security communication system itself, such as high equipment cost, large size, low stability, unproven actual security benefits, and product structure. Problems such as singleness, no unified industry standard, and large consumption of optical fiber resources are inevitable in the process of productization. In the final analysis, technological breakthroughs and industry standardization promotion are needed

Second, quantum secure communication technology mainly solves the problem of secure transmission of keys or random numbers, but key transmission is only a part of cryptographic applications. Separate key transmission from cryptographic applications will cause a series of problems due to different application modes. Key coordination and matching problems caused by
