Emerging memory architectures are proposed to address the scalability issues of current computing systems. However, they bring challenges when data security support is needed. An attacker could capture sensitive information in a program through side channels, such as memory access patterns. Moreover, emerging memory systems further complicate security support due to the new properties such as larger sharing space, data persistency, and concurrent accesses. This research aims to enable high-performance and practical memory access pattern obfuscation for current and emerging memory architectures. The approaches include co-designs from the cryptographic algorithms, target applications that need protection, and new memory architectures. The success of this project can keep improving the performance of cryptographic protocols on real computing systems and applications. The outcome will include a set of integrated, cross-domain secure architecture designs and obfuscation schemes. The project outcomes will have significant broader impacts on education, society, and national security. This project will broaden computing participation by recruiting undergraduate researchers and outreach to underrepresented groups. With a closer interaction between security and computer architecture, the proposed research will benefit a broader type of applications and thus help protect national security in the long run.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

新兴的存储器架构被提出来解决当前计算系统的可扩展性问题。然而，当需要数据安全支持时，它们就会带来挑战。攻击者可以通过侧通道捕获程序中的敏感信息，例如内存访问模式。此外，由于更大的共享空间、数据持久性和并发访问等新特性，新兴的内存系统使安全支持进一步复杂化。这项研究旨在为当前和新兴的内存架构实现高性能且实用的内存访问模式混淆。这些方法包括加密算法的协同设计、需要保护的目标应用程序以及新的内存架构。该项目的成功可以不断提高密码协议在实际计算系统和应用程序上的性能。结果将包括一套集成的、跨域的安全架构设计和混淆方案。项目成果将对教育、社会和国家安全产生更广泛的影响。该项目将通过招募本科生研究人员和向代表性不足的群体进行推广来扩大计算机参与。随着安全和计算机体系结构之间更紧密的互动，拟议的研究将惠及更广泛的应用，从而从长远来看有助于保护国家安全。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力评估进行评估，认为值得支持。优点和更广泛的影响审查标准。
