Quantum key distribution system, quantum key distribution method and device

Abstract

The present application discloses a quantum key distribution system, a quantum key distribution method and a device. Wherein, the system includes: quantum security key management equipment, quantum security key distribution equipment, quantum security key service equipment; quantum security key management equipment, used to split the system private key into At least two system sub-private keys, which are distributed to quantum-safe key distribution devices through quantum key agreement; quantum-safe key service devices, used to forward authorized private key acquisition requests to other quantum-safe key distribution devices; The quantum security key distribution device is used to obtain the identity-based authorization sub-private key from other quantum security key distribution devices through quantum key agreement, and use the threshold key sharing mechanism to reconstruct the identity-based authorization private key. Adopting the above-mentioned system can not only resist the risk of classic passwords being cracked, but also reduce the possibility of administrators maliciously leaking user data.

Description

technical field [0001] This application relates to quantum key technology, in particular to a quantum key distribution system. The present application also relates to a quantum key distribution method and a quantum key distribution device. Background technique [0002] With the development of computer and network technologies, systems that provide users with various services have emerged, for example, cloud computing systems that provide users with various services such as applications, data, and IT resources. In such a system, in order to ensure the security of the static data stored inside the system and the dynamic data generated during the process of providing services to users, it is usually necessary to use an encryption algorithm to encrypt the data. For example, in a cloud computing environment, there are two data encryption modes: an encryption mode based on certificate authentication, or an encryption mode using a cloud computing key management system.
