Comparative survey of high-performance cryptographic algorithm implementations on FPGAs

The authors present a comparative survey of private-key cryptographic algorithm implementations on field programmable gate arrays (FPGAs). The performance and flexibility of FPGAs make them almost ideal implementation platforms for cryptographic algorithms, and therefore the FPGA-based implementation of cryptographic algorithms has been widely studied during the past few years. However, a complete analysis of published implementations has not been presented previously. The authors analyse FPGA-based implementations of certain widely used cryptographic algorithms in terms of speed, area and implementation techniques. The algorithms studied in this article include the private-key cryptographic algorithms advanced encryption standard and international data encryption algorithm and certain hash algorithms. These algorithm implementations provide a good overview of the field of private-key cryptographic algorithm implementation.
