A Comparative Evaluation of Cryptographic Algorithms

Security of information has become animportant issue in data communication.Encryption has come up as a solution, andplays a vital role in information securitysystem. This security mechanism usessome algorithms to scramble data intounreadable text which can be only beingdecoded or decrypted by party thosepossesses the associated key. Thesealgorithms consume a significant amountof computing resources such as CPU time,memory and battery power andcomputation time. This paper performscomparative analysis of three algorithm;ECC, AES and RSA considering certainparameters such as computation time andcomplexity of the algorithms. Acryptographic tool is used for conductingexperiments. Experiments results are givento analyses the effectiveness of eachalgorithm
