HECTOR-V: A Heterogeneous CPU Architecture for a Secure RISC-V Execution Environment

Understand

To ensure secure and trustworthy execution of applications, vendors frequently embed trusted execution environments into their systems.

• Here, applications are protected from adversaries, including a malicious operating system.
• TEEs are usually built by integrating protection mechanisms directly into the processor or by using dedicated external secure elements.
• However, both of these approaches only cover a narrow threat model resulting in limited security guarantees.
