Influence of fault-tolerant design methods on differential power analysis resistance of AES cipher: Methodics and challenges

Many electronic systems has to fulfill strict dependability properties, especially both fault tolerance and attack resistance. These requirements usually contradict each other. The study and experiment descriptions of the possible methods how to measure these impacts are presented in this paper. Specifically, how fault-tolerant design methods affects resistance against differential power analysis attack and how the whole design can be modified to increase attack resistance will be discussed.
