用孙子剩余定理计算Hilbert类多项式

Computing Hilbert class polynomials with the Chinese Remainder Theorem

Andrew V. Sutherland

摘要:

基于孙子剩余定理的显式形式,给出了计算Hilbert类多项式H_D(X)模正整数P的一个空间有效算法.在广义黎曼假设下,该算法的时间复杂度为O(|D| ^(1/2+o(1))log P),期望运行时间为O(|D| ^(1+o(1)).我们描述了实际的优化,使我们能够处理比其他方法更大的判别式,|D|高达10^13和h(D)高达10^6。我们应用这些结果来构造配对友好的椭圆曲线的素数阶,使用CM方法。

英文摘要:

We present a space-efficient algorithm to compute the Hilbert class polynomial H_D(X) modulo a positive integer P, based on an explicit form of the Chinese Remainder Theorem. Under the Generalized Riemann Hypothesis, the algorithm uses O(|D|^(1/2+o(1))log P) space and has an expected running time of O(|D|^(1+o(1)). We describe practical optimizations that allow us to handle larger discriminants than other methods, with |D| as large as 10^13 and h(D) up to 10^6. We apply these results to construct pairing-friendly elliptic curves of prime order, using the CM method.
