Implementation of Modified RSA Approach for Encrypting and Decrypting Text Using Multi-power and K-Nearest Neighbor Algorithm

Security is the concept of keeping information secret by protecting it from unauthorized users. In a distributed medium, cryptography becomes crucial part for secure communication. This chapter presents literature survey of the previous work done by various researchers in the field of cryptography and implementation of modified approach with a fair comparison between traditional RSA and modified approach. The text of different sizes was encrypted and decrypted using modified approach. The simulation results are also shown with graphical description simultaneously.
