Key management system and method based on quantum key distribution system

Abstract

The invention provides a key management system and method based on a quantum key distribution system, and the system comprises a management party A and a support party B. The management party A at least comprises quantum key distribution equipment and key management equipment, and the support party B at least comprises quantum key distribution equipment. Quantum communication can be carried out between the management party A and the support party B through the quantum key distribution equipment. The quantum key distribution equipment is used for realizing cooperation of quantum keys of two communication parties, and the quantum keys comprise a master key, a key encryption key and a session seed key. The key management equipment is used for carrying out layered and dispersed storage protection on the master key, the key encryption key and the session seed key which are obtained by cooperation of the quantum key distribution equipment through a three-layer key protection system. According to the key management system, the security of quantum key storage can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of quantum communication, in particular to a key management system and method based on a quantum key distribution system. Background technique [0002] With the development of quantum computers and the introduction of quantum algorithms, the security of classical cryptosystems based on computational complexity assumptions has been severely challenged. In order to deal with the potential threats brought by quantum computers and quantum algorithms to classical cryptosystems, people began to study new cryptographic algorithms that can resist quantum computing attacks. Quantum cryptosystems emerged under this background. Quantum cryptography is a new type of cryptographic system produced by the combination of classical cryptographic theory and the basic principles of quantum mechanics. Different from classical cryptography systems, quantum cryptography systems use quantum states as information carriers and are ...

Problems solved by technology

[0003] Although the quantum key system is recognized as unconditionally safe in the key distribution process, it ignores the security of quantum key storage after key distribution. Generally, it is stored in plain text or encrypted with a preset key, and the encryption strength is not enough. ,There are security risks
