Fast Software Encryption: Designing Encryption Algorithms for Optimal Software Speed on the Intel Pentium Processor
Most encryption algorithms are designed without regard to their performance on top-of-the-line microprocessors. This paper discusses general optimization principles algorithms designers should keep in mind when designing algorithms, and analyzes the performance of RC4, SEAL, RC5, Blowfish, and Khufu/Khafre on the Intel Pentium with respect to those principles. Finally, we suggest directions for algorithm design, and give example algorithms, that take performance into account. 1 Overview The principal goal guiding the design of any encryption algorithm must be security. In the real world, however, performance and implementation cost are always of concern. The increasing need for secure digital communication and the incredible processing power of desktop computers make performing software bulk encryption both more desirable and more feasible than ever. The purpose of this paper is to discuss low-level software optimization techniques and how they should be applied in the design of encry...
