Quantum Encryption System and Encrypted Communication Method for Telephone Switching Network

Abstract

The invention discloses a quantum encryption system and encrypted communication method for a telephone exchange network. The encryption system includes a total quantum generation management system, a total PSTN domain and a total IMS domain quantum VPN, and PSTN domains and IMS domain quantum generation in multiple regions The management terminal, and the PSTN domain and IMS domain quantum VPN in the multiple areas, based on this system, through the quantum encryption of data packets, can realize the state grid company IMS domain phone, PSTN domain phone, IMS domain Communication between the phone and the PSTN domain phone is encrypted.

Description

technical field [0001] The invention relates to the communication field, in particular to a quantum encryption system and an encryption communication method for a telephone exchange network. Background technique [0002] According to the principle of "unified technical system, unified planning, and unified construction", the State Grid Corporation of China has made overall planning and overall planning, promoted and built an IMS (IP MultimediaSubsystem) administrative system with "stable structure, convenient operation and maintenance, reasonable resources, and rich services" across the country. switching network. At present, the provincial electric power companies in the country have basically completed the construction of the main and backup systems of the IMS core network, and the program-controlled switching based on the TDM system will be gradually withdrawn. With the rapid development of the State Grid Corporation of China's IMS network and the exponential growth of t...

AI Technical Summary

Problems solved by technology

On the one hand, the means of network attacks are constantly diversifying, and security protection is becoming more and more difficult

Second, with the deployment of the IMS system in the private network of the State Grid Corporation of China, while the switching network becomes IP-based, the possibility of network attacks and information interception becomes greater

[0006] Second, the security situation of the entire network of the traditional telephone switching network cannot be grasped in time, and it is impossible to quickly and timely determine and automatically discover network security problems

[0007] Third, there are potential safety hazards in the existing security technologies, and it is impossible to truly guarantee the absolute security of data transmission in the telephone switching network

At the same time, there are problems such as lack of security monitoring methods in the switching network, long feedback time for security issues, slow processing, and serious impact on user information security.
