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, ...
