AES s obranou proti postranním kanál?m

08.07.2004
Abstract. In implementing cryptographic algorithms on limited devices such as smart cards, speed and memory requirements had always presented 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.
