Abstract

Memory encryption with authentication protects critical applications from attackers with physical access. Memory encryption introduces memory access latency overhead due to the cryptographic computations and metadata accesses in DRAM. We propose using a metadata cache to reduce latency and report the results of an experimental and simulation evaluation of the impact of the DRAM and metadata cache on the overall latency of memory encryption schemes based on Intel SGX and Encryption for Large Memory integrity trees on an FPGA-based platform with DDR3 DRAM. We present the results of an end-to-end performance evaluation of the RISC-V RocketChip soft-core and the memory encryption with several metadata cache configurations.

内存层次结构对内存加密性能的影响

带有身份验证功能的内存加密可保护关键应用免受物理访问攻击者的攻击。由于在 DRAM 中进行加密计算和元数据访问，内存加密会带来内存访问延迟开销。我们建议使用元数据高速缓存来减少延迟，并报告了基于英特尔 SGX 的内存加密方案和基于 DDR3 DRAM 的 FPGA 平台上的大型内存完整性树加密方案的总体延迟对 DRAM 和元数据高速缓存的影响的实验和仿真评估结果。我们介绍了 RISC-V RocketChip 软核和内存加密与几种元数据高速缓存配置的端到端性能评估结果。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
