利用孙子剩余定理构造Picard曲线

Constructing Picard curves with complex multiplication using the Chinese Remainder Theorem

Sonny Arora, Kirsten Eisentraeger

摘要:

给出了一种构造有限域上Picard曲线的新算法。这在密码学中具有重要的应用,因为亏格3的曲线允许比椭圆曲线更小的密钥大小。对于含有单位立方根的六次CM-域$K$,定义并计算了一类模小素数多项式,然后利用孙子剩余定理构造了有理数上的类多项式.我们也给出了一些例子。

英文摘要:

We give a new algorithm for constructing Picard curves over a finite field with a given endomorphism ring. This has important applications in cryptography since curves of genus 3 allow for smaller key sizes than elliptic curves. For a sextic CM-field $K$ containing the cube roots of unity, we define and compute certain class polynomials modulo small primes and then use the Chinese Remainder Theorem to construct the class polynomials over the rationals. We also give some examples.
