| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we focus on isogenies over abelian varieties for isogeny-based cryptography and propose the efficient algorithms of the hash function using $(3,3)$-isogenies. We give an algebraic relation of the polynomials in the hash function algorithm and this results in about $17.2%$ reduction in complexity as compared to the implementation of the previous work. | |
