| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have developed new atomic patterns for faster elliptic curve scalar multiplication by rearranging field arithmetic and removing some unnecessary dummy operations. Atomicity concept is an alternative method to protect the algorithm from simple side-channel analysis. In contrast to previous results that used only one atomic pattern, we present the advantages of using more than one pattern and also introduce a usage of two atomic patterns for left-to-right binary scalar multiplication. As a result, cost per bit of when computing scalar multiplication is reduced by $1.36 \%$ if our new patterns are used. | |
