A design scheme of multi-channel 10G network security device is proposed to meet the demand for secure data trans-mission between severs in a data center.Using domestic high-performance FPGA and CPU,this solution establishes a VPN chan-nel through bidirectional authentication and negotiation,and implements 10-channel 10G business data protection services based on IPSec VPN technology.A test environment was built to test and verify the prototype.The results show that under a packet length of 1 400 B,each channel can achieve IPSec transmission with a throughput rate of no less than 9.4 Gb/s.
