抗物理攻击存储安全技术研究综述

Survey of research on physical attack-resistant secure memory techniques

设定处理器片上安全,围绕抗物理攻击存储安全关键技术进行研究,给出了物理攻击的定义及抗物理攻击技术的潜在应用场景;通过对安全系统模型进行比较、分析,总结了安全体系结构设计的研究现状;结合密码保护技术,回顾了单处理器结构和多处理器结构中的数据保护方法:数据机密性、数据完整性、防重放攻击技术,分析了多处理器结构中共享秘密技术及cache间安全通信技术。

On the assumption that the processor area was secure, the paper presented a research on physical attack-resistant memory security key techniques.Gave a definition of physical attack and the application scenes of physical attack-resistant techniques,summarized the research status of secure system design by analyzing the secure system models and the differences between them.Introduced the data protection methods on uniprocessor and multiprocessor archirectures, analyzed the secret sharing techniques and the secure communication techniques between caches.
