| Abstract(in English) | Since a Elliptic Curve Cryptosystem can maintain high security with a small definition field, it is suitable for a smart card with limited memory. However, we should deal with the Side Channel Attack (SCA) serious threat. The Side Channel Attack is mainly classified with Simple Power Analysis (SPA) and Differential Power Analysis (DPA). Recently, new attacks of Refined Power Analysis (RPA) and Zero-value Point Analysis (ZPA) were proposed. The technique using Randomized Initial Point countermeasure (RIP) as a countermeasure of DPA, RPA, ZPA was proposed. However, unfortunately the previous method uses the expansion method from LSB ,and requires additional memory from MSB. In this paper, we propose a new countermesure which uses the binary expansion method from MSB. |
