Abstract

The invention relates to a secure Ethernet bridge scrambling terminal based on a national cryptographic algorithm. The terminal includes an Ethernet bridge data receiving / forwarding function, a whitelist filtering function, a scrambling function, a data tamper-proofing verification function, a terminal equipment authentication function and a user use authentication function. According to a security protection scheme that is simple and practicable, is convenient to deploy, and has high cost performance, provided by the invention, the risks of deployed Ethernet terminal equipment and open network data backhaul terminal equipment can be solved by adopting a secure Ethernet bridge scrambling technology based on the national cryptographic algorithm.

Description

technical field [0001] The invention relates to an Ethernet distributed deployment device or other open network return data devices, in particular to a secure Ethernet bridge scrambling terminal based on a national secret algorithm. Background technique [0002] The risks encountered by Ethernet distributed devices or other open network backhaul data devices are as follows: [0003] 1) The exposed data has not undergone any scrambling processing, so it can be easily intercepted and restored, and even control protocol messages can be intercepted; [0004] 2) The data processing of the remote terminal and the network data processing are realized by CPU plus operating system and application software, and there is a risk of intrusion and attack. Hackers can use DDOS attacks to directly cause the entire terminal to stop working, or even use more advanced means to invade the CPU's operating system, and directly obtain the highest authority to do whatever they want; [0005] 3) T...
