Abstract(in English) | In this paper, we will propose an efficient hardware architecture of isogeny-based cryptography. The proposed architecture utilizes the newly designed multiplier over an imaginary finite field with a characteristic of a huge prime (i.e., Fp2 ) to efficiently perform the Fp2 multiplication that occupies most major part of the computation of isogeny-based cryptography. The proposed multiplier is based on an optimized residue number system (Q-RNS) and utilizes Karatsuba method to perform Fp2 multiplications in parallel. In this paper, we evaluate the designed datapath on Xilinx Kintex Ultrascale+, and show the estimation of latency when we realize an isogeny-based cryptography using the proposed multiplier. |
