Abstract:

The Advanced Encryption Standard (AES), the block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process markedly more open and transparent than its predecessor, the aging Data Encryption Standard (DES). Fifteen algorithm were submitted as to NIST in 1998, NIST choose five finalist. NIST primary selection criteria is security, performance, and flexibility. This paper is enlighten last two criteria. In this paper we have discussed software performance five AES finalist. The paper specifically compares performance the five AES finalist on a verity of common software platform: 32-bit CPU( both large and smaller microprocessors, smart cards, embedded microprocessors) and high end 64-bits CPUs. The paper includes maximum rounds crypt analyzed for each algorithm and reexamine all the performance numbers of all theses variants. We hope that this provide fairer way of comparing different algorithm and design decision for various designer. The algorithms again compare with minimal secure variants to draw a fair conclusion.
