Secure information transmission has always been of immense importance in all sorts of communication systems. In this area, cryptographic algorithms have been evolved and employed over decades. After the release of Advanced Encryption Standard (AES) most of the people have made its animations in 128-bit, which is very difficult to understand by the beginners. This paper is about complete structure of Simplified Advanced Encryption Standard (SAES) and its step by step implementation in graphics form using Flash. Aim of this paper is to represent SAES in such an easy way that it helps beginners to understand each step of key generation, encryption and decryption easily using 16-bit plain text as well as keys. Adding to the complete description of SAES, the authors also discuss few important points, which are needed in addition to understand for the implementation of Advanced Encryption Standard (AES) from SAES. In this paper authors also have proposed a general formula to calculate the length of the key for more than one round’s in AES and SAES.
