Secure and Efficient AES Software Implementation for Smart Cards

Secure and Efficient AES Software Implementation for Smart Cards
In implementing cryptographic algorithms on limited devices such as smart cards, speed and memory optimization had always been a challenge. With the advent of side channel attacks, this task became even more difficult because a programmer must take into account countermeasures against such attacks, which often increases computational time, or memory requirements, or both. In this paper we describe a new method for secure implementation of the Advanced Encryption Standard algorithm. The method is based on a data masking technique, which is the most widely used countermeasure against power analysis and timing attacks at a software level. The change of element representation allows us to achieve an efficient solution that combines low memory requirements with high speed and resistance to attacks.
