KingsGuard: Novel TEE Design Monitors Sensitive Data Propagation Despite Hardware Vulnerabilities

arXiv·low signal

KingsGuard presents a new Trusted Execution Environment design that systematically monitors and controls the propagation of sensitive data within enclaves, addressing the reality that both enclave code and underlying hardware have exploitable vulnerabilities. Unlike current TEE approaches that assume hardware isolation is sufficient, KingsGuard adds a data-flow tracking layer that functions even when isolation guarantees are undermined.
