Dorami: Privilege Separating Security Monitor on RISC-V TEEs

Mark Kuhne, Stavros Volos, Shweta Shinde

TEE implementations on RISC-V offer an enclave abstraction by introducing a trusted component called the security monitor (SM). The SM performs critical tasks such as isolating enc…

Aster: Fixing the Android TEE Ecosystem with Arm CCA

Mark Kuhne, Supraja Sridhara, Andrin Bertschi +3

The Android ecosystem relies on either TrustZone (e.g., OP-TEE, QTEE, Trusty) or trusted hypervisors (pKVM, Gunyah) to isolate security-sensitive services from malicious apps and A…
