Jacobi quartic curves , one type of elliptic curves, are widely used for efficient arithmetics and immunity to timing attacks. The order of group of rational points on Jacobi quartic curves is divisible by 2 [24, 25]. Jacobi quartic curves can provide a larger group than Huff elliptic curves, Montgomery-form elliptic … See more We construct the deterministic encoding from \mathbb {F}_q to g(s)=s(s^2-4as+4a^2-4d). g(s) is an intermediate variable for the convenience of constructing … See more (Character Sum). Suppose f is an encoding from \mathbb {F}_q into an elliptic curve E, and J(\mathbb {F}_q) denotes the Jacobian group of E, \chi is a character of J(\mathbb {F}_q). We define the character sum … See more Note that the value of r is not required to be known in computing X_2, X_3 and U; indeed, these only depend on g(r).
