Description
Technical Field
The application relates to the technical field of quantum communication, in particular to a method, a system, a terminal and a storage medium for fast authentication of data integrity based on quantum secret communication.
Background
In an information security system, the privacy and integrity of encrypted data are two important aspects. The key of the privacy security of the encrypted data is the secret storage and the secret sharing, and the integrity of the encrypted data is to reduce the risk of data tampering by providing a data hash value for verification. In the existing data integrity check, a hash algorithm and a key are generally used for carrying out hash operation on data to obtain a data hash value, the hash value and the data are sent to an opposite side in a block, after the opposite side receives the data, the same hash algorithm and the same key are used for carrying out hash operation on the data to obtain the hash value, and if the obtained hash value is the same as that sent by the opposite side, the data is not tampered.
The hash is an irreversible mapping, and a hash value can be calculated by a hash algorithm, but the original data cannot be obtained by reflection of the hash value. When the data integrity is verified through the hash value, the security of the secret key is low, the risk of being acquired and leaked in the transmission process is high, and the accuracy of the data integrity verification through the hash value is greatly reduced.
The safety and the high efficiency of quantum communication are very high, the safety quantum communication never leaks secret, which is embodied in that the secret key of quantum encryption is random, and even if the secret key is intercepted by a stealer, the correct secret key cannot be obtained, so that the information cannot be cracked; and secondly, 2 particles in entangled states are respectively arranged in hands of two communication parties, the quantum state of one particle is changed, the quantum state of the other particle is changed immediately, and any macroscopic observation and interference can immediately change the quantum state according to quantum theory to cause collapse of the particles, so that information obtained by a thief due to interference is damaged and is not original information. The BB84 protocol is a general quantum key distribution protocol, and fundamentally ensures the security of keys.
Therefore, a method, a system, a terminal and a storage medium for fast data integrity authentication based on quantum secure communication are needed to achieve the purpose of reducing the risk of data integrity verification cracking by a hash function and the risk of data tampering during data transmission.

It should be noted that the security and the high efficiency of the quantum communication are very high, and one of the security of the quantum communication is embodied in that the secret key of the quantum encryption is random, and even if intercepted by a stealer, the correct secret key cannot be obtained, so that the information cannot be cracked; and secondly, 2 particles in entangled states are respectively arranged in hands of two communication parties, the quantum state of one particle is changed, the quantum state of the other particle is changed immediately, and any macroscopic observation and interference can immediately change the quantum state according to quantum theory to cause collapse of the particles, so that information obtained by a thief due to interference is damaged and is not original information. Therefore, the quantum key replaces the traditional key to carry out hash operation for data integrity verification, and the risk of cracking of the hash function during data integrity verification can be reduced.

The data sending end generates a first message digest h1 by using a hash algorithm on the plaintext data m1 to be transmitted and the shared key N, and sends the plaintext data m1 and the first message digest h1 to the data receiving end through a transmission channel.
The data receiving end adopts the same hash algorithm to generate a second message digest h2 according to the received plaintext data m1 and the shared key N, and meanwhile, the authentication process is realized by comparing whether the values of the first message digest h1 and the second message digest h2 are the same or not.
