Researchers from Tsinghua University describe findings in signal processing.

"This paper presents a high performance Network Security Processor (NSP) system architecture implementation intended for both Internet Protocol Security (IPSec) and Secure Socket Layer (SSL) protocol acceleration, which are widely employed in Virtual Private Network (VPN) and e-commerce applications. The efficient data transfer skeleton and optimized integration scheme of the parallel crypto engine arrays lead to a Gbps rate NSP, which is programmable with domain specific descriptor-based instructions for Gbps throughput IPSec and SSL applications," scientists in Beijing, People's Republic of China report.

"The descriptor-based control flow fragments large data packets and distributes them to the parallel crypto engine arrays, which fully utilizes the computation resources and improves the overall system data throughput. A prototyping platform for this NSP design is implemented with Xilinx XC3S5000 based FPGA chip set," wrote H.X. Wang and colleagues, Tsinghua University.

The researchers concluded: "The design gives a peak throughput for the IPSec ESP tunnel mode of 1.851 Gbps with over 1600 full SSL handshakes per second at a clock rate of 150 MHz."

Wang and colleagues published their study in the Journal of Signal Processing Systems for Signal Image and Video Technology (A Gbps IPSec SSL Security Processor Design and Implementation in an FPGA Prototyping Platform. Journal of Signal Processing Systems for Signal Image and Video Technology, 2010;58(3):311-324).
