Fast Software Encryption: Designing Encryption Algorithms for Optimal Software Speed on the Intel Pentium Processor

ABSTRACT: Most encryption algorithms are designed without regard to their performance on top-of-the-line microprocessors. This paper discusses general optimization principles cryptographers 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 that take performance into account.
