Abstract:

Currently, most network devices are developed base on foreign software and hardware. The core technology is controlled by others. After the Snowden leaks, some backdoors were publicly announced, which brought much latent dangers to our country. Because of the background, designed an architecture which is parallel processing by several Loongson CPU, due to the lack of performance for single Loongson CPU, and base on the architecture, developed a security protection gateway, which can be deployed in the entrance of the information center in network, and it has many functions such as firewall, IPS, and security access control. It improved the level of independence and controllable, and covered the shortage of performance and reliability for domestic Loongson CPU, also it guaranteed the security and controllable for the information center and user network.

Key words: Loongson, security protect, firewall, IPS, security access control
