Abstract(in English) | Jao et al. proposed SIDH, a key exchange protocol based on isogeny between supersingular elliptic curves. It is expected to be a candidate for quantum-resistant cryptography. Hutchinson et al. proposed the CCP model, which is an efficient method for parallel computation of isogenies required for SIDH. In this paper, we propose an extension of the CCP model for parallel computation of isogenies. The proposed method is compared with the existing methods, and it is shown that the proposed method is more efficient in 2-parallel environment for the parameters used in practice. |
