Random Euclidean addition chain generation has proven to be an efficient low memory and SPA secure alternative to standard ECC scalar multiplication methods in the context of fixed base point (Herbaut et al. in Progress in Cryptology-INDOCRYPT 2010, volume 6498 of LNCS. Springer, Berlin, pp 238–261, 2010). In this work, we show how to generalize this method to random point scalar multiplication on...
In this paper, we improved the method proposed in [1] which was designed to detect errors in the elliptic curve scalar multiplication algorithm (ECSM). The algorithm we propose is SPA-secure and safe against recent data and instruction cache timing attacks.
