Abstract

Quality of service is a relevant term in today’s computing scenario. Quality is a subjective issue; we need to devise some parameters, based on which quality can be measured. In this paper, we devised metrics on the basis of which we compared cryptographic strengths of ciphers namely SDES (Simplified Data Encryption Standard), DES (Data Encryption Standard), 2DES (Double Data Encryption Standard), BLOWFISH, CAST (Carlisle Adams Stafford Tavares) –128  and found the strongest and weakest cipher. This comparison has been made by using metrics namely Block size, Encryption key length, Complexity of round function F, Confusion & Diffusion, S-boxes, Number of operators involved and Number of Cycles. After analyzing all the ciphers, we have arranged them in tables with respect to each metric.
