Secure Communication Method Based on Packet Vertical Random Split and Path Separation Transmission

Abstract

The invention discloses a new type of high-security confidential communication method based on group longitudinal random division and path separation transmission, adopting the security mechanism of group longitudinal random division and separation path transmission control to prevent the adversary from obtaining the complete secret IP message through monitoring. In this paper, the real IP address of the original IP message is hidden through the shadow IP subnet mechanism and the encapsulation and transmission of the three-section secure relay tunnel, making it difficult for the adversary to guess the real communication user by monitoring the content of the communication data. The novel high-security and secret communication method designed by the present invention can establish a high-safety and secret communication VPN network on the public Internet at a relatively low investment cost, can defend against security threats from various monitoring means, and can effectively fight against The deciphering analysis attack of the quantum computer with the ability can be used not only as a secure VPN for confidential communication, but also as a secure VPN for commercial confidential communication with higher security requirements.

Description

technical field [0001] The invention relates to a secret communication method based on group longitudinal random subdivision and path separation transmission. Background technique [0002] At present, developed countries are actively researching and developing quantum computers, and it is expected that a truly large-scale quantum computer will appear within a few years. Due to the superposition and entanglement characteristics between qubits, the computing power of quantum computers can increase exponentially with the increase in the number of qubits. Quantum computing will have a huge impact on secure communication based on traditional networking modes and transmission methods. security threats. [0003] In the existing public Internet, there are always some security loopholes in various network devices, and it is easy for an opponent to implant a monitoring Trojan horse through network attacks, and it is easy to obtain communication data between VPN subnets. Moreover, ev...
