Cryptography algorithms are divided into symmetric and asymmetric key cryptography. In this paper, the authors present the comparison between two cryptographic algorithm AES and Blowfish algorithm on the basis of ARM implementatiom.LPC 2148 from NXP Philips family kit is used for implementation. In embedded system security blowfish is suitable. For comparison, they considered points like memory size, encryption cycle, and decryption cycle for both algorithms on ARM7 etc. For small embedded system like mobile, smart card etc Blowfish is best algorithm for security.
