Confidential-Computing

In the race to secure cloud applications, AWS Nitro Enclaves have emerged as a powerful tool for isolating sensitive workloads. But with great power comes great responsibility-and potential security pitfalls. As pioneers in confidential computing security, we at Trail of Bits have scrutinized the attack surface of AWS Nitro Enclaves, uncovering potential bugs that could compromise even these hardened environments.

Creating reproducible builds for SGX enclaves used in privacy-oriented deployments is a difficult task that lacks a convenient and robust solution. We describe using Nix to achieve reproducible and transparent enclave builds so that anyone can audit whether the enclave is running the source code it claims, thereby enhancing the security of […]
