Abstract :In the recent years, alternate models of elliptic curves have been studied. Such well-known models are Edwards curves, Jacobi intersections and Jacobi quartics, Hessian curves, Huff curves, and their variants to the more common Weierstrass curve. These models sometimes allow for more efficient computation on elliptic curves or provide other features of interest to cryptographers, such as resistance to side-channel attacks. In this paper, we first give the alternate models of elliptic curves emphasizing point addition and point doubling formulae with computational costs, the suggested improvements in each model and then countermeasures to side channel attacks if any. We also describe the geometric interpretation of the addition law in each model.
Keywords : alternate models of elliptic curves, side channel attack, unified addition formulae, computational cost
