Simplified AES for Low Memory Embedded Processors

Abstract

Embedded Processors have 2 main constraints: Memory and Processing Power. Encryption algorithm running on such processors
should be specially customized to overcome these 2 constraints. AES[2] is a well-known standard algorithm for encryption but its memory and
processing power requirements are very high. This paper proposes modifications to AES to optimize it to overcome above 2 constraints.
