Analysis of Advanced Encryption Standards

© 2010 GSTF DOI: 10.5176_2010-2283_1.1.24 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 are security, performance, and flexibility. This paper enlightens the last two criteria. In this paper we have discussed software performance of five AES finalist. The paper specifically compares performance of 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.
