Exploring Enclaves

August 4, 2019

July 25 was a gorgeous summer day. It’s also when the Keystone Enclave team hosted the 2019 Open-Source Enclave Workshop at University of California, Berkeley. Industry and academic luminaries representing 23 organizations gathered at Wozniak Lounge, Soda Hall to deliver 25 talks.

Keystone Enclave is an open-source project for building trusted execution environments (TEE) with secure hardware enclaves, based on the RISC-V architecture. Its goal is to build an open-source secure hardware enclave, accessible to everyone in industry and academia.

Turning IoT Stack Sideways

July 6, 2019

At the Zurich RISC-V Workshop in June, Professor Sandro Pinto and his team at Universidade do Minho, Portugal, presented their work that describes the first fully functional framework for developing secure Internet-of-Things (IoT) systems on RISC-V processors. The proposed horizontal software stack is based exclusively on a number of open-source, commercial-grade technologies readily available today.

The Case for RISC-V

Nov 15, 2018

In our engagements with partners, customers and investors, we frequently get asked – “Why RISC-V?”  Wouldn’t it make more sense to build a simple Trusted Execution Environment for a larger installed base like ARM or x86?

Here’s why we believe in RISC-V
