Performance of Cryptographic Algorithms based on Time Complexity

摘要

Nowadays, a tremendous amount of data is produced every single day by computational systems and electronic instruments, whether its an online transaction or data manipulation over the internet, security has dependably remained the best concern in any correspondence communication system. The amount of information to be exchanged is not the problem. The essential variable is the Channel, through which the data is transferred, ought to be secured. So in terms of secure transmission of data, the best technique usually used these days is cryptography. Cryptography is a procedure of making data incomprehensible to an unapproved individual. Different cryptographic algorithms can be utilized in a very efficient manner. In a perfect world, a user needs the best cryptographic algorithm with low cost and high in performance measure. So for the critical needs of the user, the cryptographic algorithm chose the best algorithm amongst existing algorithms. This research paper presents a neat and clean study of various cryptographic algorithms (DES, 3DES, AES, RSA) based on the computational complexity and performance measure.
