论文摘要
描述了使用二进制不可约GOPPA代码和经典解码技术的NiederReiter公开密码系统解密算法的故障注入框架。特别是，我们在秘密钥匙的一部分中获得低级多项式方程。对于最终的多项式方程系统，我们提出了有效的解决策略，并展示了如何将某些解决方案扩展到替代秘密密钥。我们还提供了预期所需故障注射的预期数量的估计，将框架应用于最新的安全级别，并提出针对此类故障攻击的对策。
A fault injection framework for the decryption algorithm of the Niederreiter public-key cryptosystem using binary irreducible Goppa codes and classical decoding techniques is described. In particular, we obtain low-degree polynomial equations in parts of the secret key. For the resulting system of polynomial equations, we present an efficient solving strategy and show how to extend certain solutions to alternative secret keys. We also provide estimates for the expected number of required fault injections, apply the framework to state-of-the-art security levels, and propose countermeasures against this type of fault attack.
