This simulation study and software is specifically designed for the teachers and instructors in colleges and universities. Our proposed system is a graphical simulation of Rijndael, Mars, and RC6 of AES and their working in VC++. Instructors in universities will be able to teach the difficult to understand AES algorithms in very easy way, without too much efforts and the wastage of time. Our objective is to utilize the computer resources to facilitate the students to learn how Advance Encryption Standard Algorithms works. Our simulation shows steps that are used to encrypt the text with key...
