Zeta functions of equivalence relations over finite fields
ABSTRACT. We prove the rationality of the generating function associated to the number of equivalence classes of Fqk -points of a constructible equivalence relation defined over t...

Estimating the Size of the Image of Deterministic Hash Functions to Elliptic Curves
Let E be a non-supersingular elliptic curve over a finite field Fq. At CRYPTO 2009, Icart introduced a deterministic function Fq → E(Fq) which can be computed efficiently, and ...

Remarks on the Schoof-Elkies-Atkin algorithm
Abstract. Schoof’s algorithm computes the number m of points on an elliptic curve E defined over a finite field Fq. Schoof determines m modulo small primes using the character...

An Extension of Kedlaya's Point-Counting Algorithm to Superelliptic Curves
We present an algorithm for counting points on superelliptic curves yr = f(x) over a finite field Fq of small characteristic different from r. This is an extension of an algorit...

Elliptic Curves with a Given Number of Points
We present a non-archimedean method to construct, given an integer N ≥ 1, a finite field Fq and an elliptic curve E/Fq such that E(Fq) has order N.

Algebraic Constructions of Space-Frequency Codes
— Recently an algebraic construction of (nt × Q) space-frequency (SF) codes over finite field Fq was proposed for use in MIMO-OFDM systems, where nt is the number of transmit ...

Fast Modular Composition in any Characteristic
We give an algorithm for modular composition of degree n univariate polynomials over a finite field Fq requiring n1+o(1) log1+o(1) q bit operations; this had earlier been achiev...
