Koblitz curves belong to a special class of binary curves on which the scalar multiplication can be computed very efficiently. For this reason, they are suitable candidates for implementations on low-end processors. However, such devices are often vulnerable to side channel attacks. In this paper, we propose a new countermeasure against side channel attacks on Koblitz curves, which utilizes a fixed-pattern recoding to defeat simple power analysis. We show that in practical cases, the recoding can be performed from left to right, and can be easily stored or even randomly generated.
