Optimized Key Management System in Cryptographic algorithms for Data Security

Abstract

Data security is an important parameter in data communication. It is the prime requirement of all the organizations in order to keep their important information safe from hackers. There are various techniques, which are used to keep the data confidential from hacker. These are passwords, cryptography and biometrics. Passwords are not so good for this task due to their low entropy. Encryption is process of converting plaintext into cipher text. The strength of the cryptographic technique comes from the fact that no one can read the information without altering its content. Cryptography is the best solution for the above problem. In this report comparative study of various encryption algorithms has been done. From the Literature Survey, various observations and gaps have also been found. Objectives have been drawn from the observations and gaps. Optimization of keys for data encryption has also been done. Using dynamic keys simulation results have been achieved using MATLAB. Finally, comparison of our approach with existing algorithms has also been done on the basis of process time and working time. Future scope of the work has also been discussed in last chapter.
