| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In now days, light weight system like Iot(Internet of Things) and FPGA have attracted many researchers and have applied to a lot area in IT field. Among most of these systems, an secure communication channel is very important to ensure the confidentiality, integrity and availability of information. In the other side, as one of the most famous cryptosystem, ECC(Elliptic Curve Cryptography) was proposed in 1985 and applied widely around 2005. The main advantage of this cryptosystem is it can still have same security level with shorter key length compare with other crypto scheme. When combined ECC with new light weight system, an efficient compact algorithm is very necessary. In this paper, we make an detailed analysis about the most time-consuming operation, scalar multiplication algorithm in GLS254 curve. We focused on the generality and executability of this algorithm on the new proposed coordinates. | |
