Critical Analysis of Various Cryptographic Algorithms

Abstract

Current era is digital and has elite advancement in technology, almost in every field things are becoming technology friendly. It is the need to provide security to sensitive information in this fast growing technical world. Cryptography is one of the very popular fields of network security that deals with conversion of sensitive data into one which could not be understood by anyone without the secret key. Many researchers has worked in the area of cryptography and developed many algorithms in different period and providing security to the travelling data. It is need to know the strengths and weakness of each algorithm before using and suggesting to anybody to use one. After critically analyzing existing standard cryptographic algorithms on parameters like throughput, power consumption and memory usage on DES, TDES, AES, Blowfish, Twofish, Threefish, RC2, RC4, RC5 and RC6, it has been concluded that which algorithm will suit in which situation.
