摘要
边信道攻击利用边信道来危害传统密码学方案的安全性,抗泄漏密码学的研究则可以抵抗这种攻击。安全的抗泄漏密码学方案的设计必须在一个合适的泄漏模型中。文中介绍了目前存在的几种主要的泄漏模型,包括计算泄漏、相对泄漏模型、有界恢复模型、持续泄漏模型、事后泄漏模型等,并论述了各个模型下的一些主要的研究成果和研究进展。
Side-channel attacks scheme. The research on leakage use side channels to endanger the safety of traditional cryptography -resilient cryptography can capture the attacks. A suitable leakage model is necessary for the design of safe leakage-resilient cryptography scheme. Several main leakage models at present are introduced in this paper, including only computation leaks information, the relative-leakage model, the bounded-retrieval model, continual leakage etc. Some main research results and research progress in every model are also discussed on.
