We are from the first research group in China that has been focused on TEE including Intel SGX, AMD SME/SEV, ARM TrustZone and RISC-V since 2012. Our papers are published on top-tier conferences including ISCA, HPCA, USENIX Security, CCS, USENIX ATC, NDSS, MobiSys, EuroSys, etc. In 2015, we released T6, the first open-source TEE OS in China, which evolves into a commercial product and gets deployed in tens of millions of devices.
Our project, ShadowEth, applies TEE to public blockchain and supports private smart contract in a practical way. The related paper was accepted in Jan 2018, which is the first peer-reviewed paper discussing privacy and scalability on public blockchain.
