摘要:
在众多被提出用于后量子时代的密码方案族中,有一组相对未被充分探索的例子来自基于群的密码学。该领域较核心的方案之一是所谓的半直积密钥交换(SDPKE),它是 Diffie-Hellman 密钥交换的一种推广,并且有望实现后量子安全。在本报告中,我们综述了与 SDPKE 相关的文献现状,对安全性进行了高层讨论,并全面概述了已提出的平台以及与每个平台相关的主要密码分析思想。
英文摘要:
Of the many families of cryptographic schemes proposed to be post-quantum, a relatively unexplored set of examples comes from group-based cryptography. One of the more central schemes from this area is the so-called Semidirect Product Key Exchange (SDPKE), a generalisation of Diffie-Hellman Key Exchange that is plausibly post-quantum. In this report we survey the state of the literature relating to SDPKE, providing a high-level discussion of security, as well as a comprehensive overview of the proposed platforms and the main cryptanalytic ideas relevant to each.
