This paper deals with the question of the influence of the design of cryptographic algorithm on their side channel vulnerability. On the example of the DPA attack by Kocher the complexity of the attack and their dependency on algorithmic parameters is analyzed. It is shown that the careful selection or design of algorithms can increase the security of implementations of algorithms in addition to and independent from conventional DPA attack countermeasures.
