Feature / Discussion: March 2007(U) The use of Field Programmable Gate Arrays (FPGAs) in Type I Cryptographic equipment has historically been limited. While FPGA use is allowed, restrictions on how they are used can result in inefficient processing and an increase in system size, weight and power. For example, redundancy and isolation of functionality is required through physically separate devices. This paper introduces new technology that will provide the industry with an FPGA-based single-chip cryptographic solution.

(U) The National Security Agency (NSA) and Xilinx have been working together to bring the advantages of FPGA technology to the High Assurance industry. Utilizing the Xilinx Virtex-4 FPGA, the NSA and Xilinx have developed a design flow and verification process based on NSA requirements for high-grade cryptographic processing. This paper will outline the design flow process and summarize the results of the evaluation effort.
