Abstract(in English) | Most current hyperelliptic curve cryptosystems (HECC)use the Cantor algorithm in hyperelliptic additions for encryption and decryption.It has been reported that hyperelliptic curve cryptosystems are more than several times slower than elliptic curve cryptosystems (ECC).It is then an interesting and challenging question that if the HECC could be faster than the ECC.Recently, Harley proposed a faster algorithm of addition on genus two hyperelliptic curves.In the first part of this paper, we show an improvement of the Harley algorithm which needs less computation then faster than the elliptic addition.The second part of the paper is a tentative implementation of the genus two HECC using the improved Harley algorithm, comparing with the ECC, which shown that the performance of the HECC is actually equal to that of the ECC. |
