RISC-V TEE “Penglai Enclave” formally entered StarFive chip platform

Penglai Enclave will convey the security efficiency of StarFive’s chip platform to a better stage!

July 12, 2022 — At current, {hardware} safety faces many challenges. Because of the closed nature of mainstream chip producers previously, there’s a lack of a primary line that may accumulate safety options in China. With a view to meet the business’s necessities for safety, efficiency and scalability, and obtain the objectives of excessive effectivity, controllability and mass manufacturing, the Institute of Parallel and Distributed Techniques (IPADS) of Shanghai Jiaotong College has open sourced a brand new trusted execution “Penglai Enclave” primarily based on the RISC-V structure.

Enclave, often known as TEE(Trusted Execution Setting), is a safe space constructed by underlying software program and {hardware} in a pc system. Safety of code execution and digital property. “Penglai Enclave” begins from Enclave/TEE and offers a safety answer for software program and {hardware} collaboration. As Professor Yubin Xia of Shanghai Jiaotong College IPADS mentioned: Safety is altering from “price” to “characteristic”, and the system safety of software program and {hardware} coordination is the important thing underlying supporting know-how that triggers modifications.

“Penglai Enclave” is presently essentially the most superior open supply trusted execution surroundings primarily based on the RISC-V platform. It may well isolate a number of remoted environments within the RISC-V surroundings, and security-sensitive duties can run within the remoted surroundings to keep away from malicious applications, privileged software program assaults. In contrast with related glorious programs at dwelling and overseas, “Penglai Enclave” has an order of magnitude benefit in scalability (variety of remoted environments, safe reminiscence) and system efficiency, and might help high-concurrency and low-latency situations akin to serverless computing.

The RVspace open supply neighborhood ( has additionally opened a “Penglai Enclave” space, the place customers can view and take part in discussions in actual time. In keeping with reviews, the transplantation of “Penglai” on the Saifang {hardware} platform has made progress in phases, and it’s anticipated to be formally supported quickly. “Penglai Enclave” will work with StarFive’s chip platform to create a safe RISC-V {hardware} base for the business.
