E1 group encryption system and encryption method based on quantum technology

Abstract

The invention provides an E1 group encryption device based on a quantum key distribution technology. The device comprises quantum key distribution equipment. The quantum key distribution equipment isconnected with an E1 group encryption device through a key service interface, the quantum key distribution equipment is connected with target quantum key distribution equipment through a quantum channel and a classic channel, and the E1 group encryption device is connected with the target E1 group encryption device through the classic channel. The invention further provides an E1 group encryptionmethod based on the quantum key distribution technology. Secondary encryption of trunk line transmission information is realized; confidential application services based on quantum keys, such as voice, point-to-point computer communication, fax and teleconference, are provided for users, the practicability of fusion of a quantum secret communication technology and a classical transmission networkis promoted, research, development and application of the quantum secret key technology are effectively verified, and the actual security of an information network is improved.

Description

technical field [0001] The invention belongs to the technical field of quantum information processing, and relates to an E1 group encryption system and an encryption method based on quantum key distribution technology. Background technique [0002] In my country's digital communication network system, E1 is a commonly used transmission and interface specification, and is widely used in data transmission links between base stations, switching offices, packet networks, and frame relay networks. The existing E1 group encryption device is mainly used to solve the secondary encryption of link transmission information, and provide users with confidential communication services such as voice, data, fax, and video conference. In the key management and distribution mechanism, the public key is mainly managed and distributed through the key distribution center KDC, usually using a two-layer key structure: session key and master key, where the session key is multiplexed on the trunk T...
