Composite high-security IP secure communication method with true random change key

Abstract

The invention discloses a composite high-security IP secure communication method with a true random change of a secret key. The system comprises an IP encryption processing device and an IP decryptionprocessing device. The IP encryption processing device comprises a quantum true random number generator module, a Hash operation module, a full-IP format hidden encryption module and a tunnel transmission parity segmentation module which are sequentially connected, and the tunnel transmission parity segmentation module is respectively connected with the two packet encryption tunnel packaging modules. The IP decryption processing device comprises two tunnel deblocking packet decryption modules, a tunnel receiving odd-even combining module, a full-IP format hiding decryption module and a Hash operation module. According to the method, a high-security secure communication IP network can be established on the public Internet at a low cost. Attack threats of various existing password analysisdecoding technologies can be resisted, decoding analysis attacks of a high-performance computer with high computing power can be effectively resisted, and the method can be used for various secure communication with high security requirements.

Description

technical field [0001] The invention relates to a composite high-safety IP secret communication method in which keys are truly randomly changed. Background technique [0002] At present, high-performance computing technologies such as quantum computing and neural network computing are developing rapidly, which will provide a way to accelerate computing for cryptanalysis and deciphering technology. The combination of high performance computing and cryptanalysis technology will pose a serious security challenge to the existing secure communication system. [0003] In the existing public Internet, there are always some security loopholes in various network devices, and it is easy for opponents to implant monitoring Trojans through network attacks, and it is easy to obtain communication data between IP subnets. Moreover, even if the IP subnets are directly connected based on a dedicated optical cable, the optical signal transmitted in the optical fiber is easy to be monitored, ...
