新兴的非易失性存储器（NVM）正接近大规模生产阶段。 NVM 的持久性功能支持许多有趣的应用程序和功能，例如快速恢复、暂存和直接访问持久性文件。另一方面，由于数据残留，数据持久化扩大了攻击面。此外，由于预计会恢复内存数据，因此必须正确恢复和恢复任何附带的安全元数据。虽然安全处理器的主要概念已经存在了几十年，但由于写耐久性、弹性、性能和安全性之间的权衡，设计能够在系统崩溃/重新启动时保持安全性的持久安全处理器尤其具有挑战性。在本文中，我们讨论了该领域的最新进展、挑战和未来的研究机会。
Emerging Non-Volatile Memories (NVMs) are getting close to their mass production stage. The persistence feature of NVMs enables many interesting applications and capabilities such as fast restoration, staging and direct access of persistent files. On the other hand, data persistence enlarges the attack surface due to data remanence. Additionally, since the memory data is expected to be restored, any accompanying security metadata must be recovered and restored correctly. While the main concepts of secure processors have been there for decades, designing persistently secure processors that are able to maintain security across system crashes/reboots is particularly challenging due to the trade-offs between write-endurance, resilience, performance and security. In this paper, we discuss the recent advances in this domain, challenges and future research opportunities.
