• 論文抄録 / 内容記述: Handling confidential information has become an increasingly important concern among many areas of society. However, current computing environments have been still vulnerable to various threats, and we should think they are untrusted. Trusted Execution Environments (TEEs) have attracted attention because they can execute a program in a trusted environment constructed on an untrusted platform. Particularly, the RISC-V Keystone is one of the interesting TEEs since it is a flexibly customizable and fully open-source platform. On the other hand, as same as other TEEs, it must also delegate I/O processing, such as file accesses, to a host OS, resulting in the expensive overhead. For this problem, we thought utilizing byte-addressable non-volatile memory (NVM) modules is a useful solution to handle persistent data objects for TEEs. In this paper, we introduce a prototype implementation of NVM support for the Keystone. Additionally, we evaluate it on the Freedom U500 built on a VC707 FPGA dev kit.
