| Abstract(in English) | In the execution of signature on a smart card, side channel attacks such as simple power analysis (SPA) have become serious threat. There are the fixed procedure method and the indistinguishable method for SPA resistant methods, The indistinguishable method conceals all branch instructions by using indistinguishable addition formulae but may reveal the hamming weight when an addition chain with unfixed hamming weight is used. In this paper, we give an indistinguishable addition formulae of hyperelliptic curve. We also give algorithms which executs in fixed-hamming-weight representation with or without computation table. These method works for indistinguishable addition formulae. |
