Trusted Execution Environments (TEEs): Confidential Aggregation
- Confidential Computing Architecture: How the system leverages AMD SEV-SNP, Intel SGX/TDX, and AWS Nitro Enclaves to protect sensitive model updates from compromised host OSs or hypervisors.
- Nanosecond-Scale Performance: An analysis of benchmarks showing that Federated Averaging executes in ~35–36 nanoseconds, while robust Multi-Krum selection takes only ~3.5 nanoseconds within the TEE.
- The Ingress Pipeline: Understanding the specialized data flow that moves packets from an XDP-like ingress view directly into TEE memory for processing, minimizing overhead.
- Hardened Rust Design: Why a minimalist runtime is critical for reducing the attack surface and ensuring the integrity of the Byzantine-resilient aggregation logic
