Abstract :
In this paper, we propose a new randomization method to resist differential side-channel analysis (DSCA) attacks based on elliptic curve isogenies. The basic idea is to map the elliptic curve through random isogenies to conceal the execution of the point multiplication algorithm in elliptic curve cryptosystems (ECC). Differed from the existing countermeasures against DSCA, the proposed secure algorithm does not sacrifice the computational cost of the point multiplication algorithm.
