Data integrity rapid authentication method and system based on quantum secret communication, terminal and storage medium

Abstract

The invention provides a data integrity rapid authentication method and system based on quantum secret communication, a terminal and a storage medium. The method comprises the steps that a data sending end and a data receiving end obtain a quantum shared key; the plaintext data of the data sending end and the shared key are subjected to hash operation to generate a first hash value, and the plaintext data and the first hash value are sent to the data receiving end; hash operation is performed on the received plaintext data and the shared key to generate a second hash value; the first hash value is compared with the second hash value to verify data integrity. According to the invention, a quantum key is used to replace a traditional key to carry out hash operation so as to carry out data integrity verification; according to the method, the risk that the hash function is cracked when data integrity verification is carried out can be reduced, authentication needs to be carried out on thetwo communication ends during data communication to ensure authenticity and integrity of data, rapid authentication needs to be carried out during large-scale communication, and data integrity and authenticity verification can be rapidly achieved by adopting the quantum key to carry out hash operation.

Description

technical field [0001] The present application relates to the technical field of quantum communication, in particular to a fast data integrity authentication method, system, terminal and storage medium based on quantum secure communication. Background technique [0002] In an information security system, the privacy and integrity of encrypted data are two very important aspects. The key to the privacy security of encrypted data lies in confidential storage and confidential sharing. The integrity of encrypted data is to reduce the risk of data tampering by providing data hash value for verification. Existing data integrity checks generally use a hash algorithm and a key to hash the data to obtain a data hash value, and send the hash value and data to the other party. After receiving the data, the other party uses the same If the hash value obtained is the same as that sent by the other party, it means that the data has not been tampered with. [0003] Hash is an irreversibl...
