A randomized cryptographic algorithm and its simulation in C and MATLAB with its hardware implementation in Verilog HDL

Fascinating commerce activities, transactions and services are possible if communications over open networks can be conducted in a secure manner. An effective solution to securing communications over open networks is to apply cryptography. Encryptions, digital signatures, password-based user authentication, are some of the most basic cryptographic techniques for securing communications. But, however, for many ldquofancierrdquo applications, the basic cryptographic techniques are no longer adequate. Hence, the need of the hour is an efficient but simple, encryption and decryption algorithm for encrypting any kind of data. Also, the keys required for encryption and decryption must be randomized and randomly generated from the changing data bits. Our newly proposed algorithm humbly tries to satisfy the above two criteria to some extent.
