TEE-SHirT: Scalable Leakage-Free Cache Hierarchies for TEEs

Network and Distributed System Security (NDSS) Symposium 2024 · Day 1 · Side-Channel Attacks
The talk "TEE-SHirT: Scalable Leakage-Free Cache Hierarchies for TEEs," presented by Kerem Arikan at the NDSS Symposium, addresses a fundamental and persistent challenge in secure computing: protecting Trusted Execution Environments (TEEs) from **cache side-channel attacks**. These attacks exploit the physical sharing of cache resources to infer sensitive information, effectively compromising the logical isolation that TEEs like Intel SGX are designed to provide. Recent demonstrations of such attacks against SGX underscore the urgent need for robust physical isolation mechanisms to complement the existing logical safeguards. TEE-SHirT proposes a comprehensive security framework to integrate leakage-free cache hierarchies directly into TEE designs.
