Implementation of Modified RSA in MATLAB

In this Cyber age almost every communication is done through computers via different interconnected networks and over internet. This communication involves simple chatting to e-mails, business over internet, e-commerce. These involve useful data but also financial and personal data. Financial and personal data needs security. For this different security mechanisms developed. One is to make data unreadable. The various cryptographic techniques are private key cryptography e.g. DES, public key cryptography e.g. RSA. The RSA is the most popular public key cryptographic algorithm. In this paper RSA is modified using pseudo random number and implemented in MATLAB. RSA involves complex and intensive computation.And MATLAB is known software package for high performance numerical computation and visualization.
