The invention discloses a database encryption method based on a quantum random number, and relates to the field of database encryption. The method comprises the following steps: 1, serial number acquisition: an information sending end sends a request to a database, the database randomly generating a serial number and verification information through a quantum random number generator, and the database sends the serial number and the verification information back to the information sending end; 2, key acquisition: a local server is arranged in the information sending end, a code book is arranged in the local server, and after the information sending end receives the serial number, the serial number is input into the code book to obtain a key; 3, file transmission: after the key is acquired, a file is encrypted according to an encryption algorithm, and the encrypted file and the verification information are transmitted to an information receiving end; and 4, file decryption. According to the method, the serial number is randomly generated through the quantum random number generator, and then the key is generated through the serial number, so that the randomness of the key is ensured; and meanwhile, the key is acquired in two clients, so that the key leakage is avoided.
Description
technical field [0001] The invention relates to the field of database encryption, in particular to a database encryption method based on quantum random numbers. Background technique [0002] Quantum information is a new discipline developed by the combination of quantum physics and information technology, which mainly includes two fields: quantum communication and quantum computing. Quantum communication mainly studies quantum cryptography, quantum teleportation, long-distance quantum communication technology, etc.; quantum computing mainly studies quantum computers and quantum algorithms suitable for quantum computers. [0003] At present, the mass production of Internet devices involves password generation usage scenarios. Pseudo-random numbers are easy to be cracked by records, which can easily lead to key leakage and data loss. Contents of the invention [0004] In order to solve the deficiencies mentioned in the above-mentioned background technology, the purpose of t...
