最近由bonnetains - schrottenloher和Peikert在Eurocrypt 2020上独立报道的分析,显着降低了基于等基因的交换群作用协议CSIDH提供的估计量子安全性。本文通过对量子准直筛攻击相关计算成本的综合分析,重新审视了CSIDH量子安全问题。此外,我们提出了一组素数,可用于获得达到NIST安全级别1、2和3的CSIDH的大型实例。最后,我们提供了一个c代码的常量时间实现,这些CSIDH大型实例由新的vsamulu公式支持
Recent analyses reported independently by Bonnetain-Schrottenloher and Peikert in Eurocrypt 2020, significantly reduce the estimated quantum security provided by the isogeny-based commutative group action protocol CSIDH. In this paper the CSIDH quantum security is revisited through a comprehensive analysis of the computational cost associated to the quantum collimation sieve attack. Furthermore, we propose a set of primes that can be applied to obtain large instantiations of CSIDH achieving the NIST security levels 1, 2, and 3. Finally, we provide a C-code constant-time implementation of those CSIDH large instantiations supported by the new Vélu formulae
