ANALYZING THE SUPERLATIVE SYMMETRIC CRYPTOGRAPHIC ENCRYPTION ALGORITHM ( ASCEA)

[摘要] Cryptology is a science that deals with codes and passwords. Cryptology is alienated into cryptography and cryptanalysis. The Cryptography produces methods to protect the data, and cryptanalysis hack the protected data. Cryptography provide solutions for four different security areas - confidentiality, authentication, integrity and control of interaction between different parties involved in data exchange finally which leads to the security of information .Encryption algorithms play a key role in information security systems. This paper provides critical analysis of six most common encryption algorithms namely: DES, 3DES, RC2, Blowfish, AES (Rijndael), and RC6. A comparative study has been carried out for the above six encryption algorithms in terms of encryption key size ,block size, Number of Rounds ,Encryption/decryption time ,CPU process time, CPU clock cycles (in the form of throughput), Power consumption. And these comparisons are used to conclude the best Symmetric Cryptography Encryption algorithm.
