A Research on Performance Evaluation for Some Cipher Models Based on Analytical Survey

Cryptography is the fundamental building block for designing the speedy and reliable cypto-system. These are several mathematical functions like modulus, hash and exponent to be sued in different crypto-algorithum. Security level of a cipher depends on its key size, key selection and key management. Inventors have developed many cryptosystems called cipher to be used in software and hardware level security devices. The present paper focuses the characteristics and performance related issues for several symmetric and asymmetric ciphers.
