Researchers have developed dstack-capsule, a new Kubernetes platform that enables Pod-level remote attestation for confidential workloads on Intel TDX. This innovation allows multiple Pods to share a single Confidential VM while each maintains independent, hardware-backed proof of identity. The system uses a two-layer attestation architecture, including a privilege fuse mechanism and dynamic Pod identity embedding in TDX Quotes, to provide granular verification without the resource overhead of per-VM isolation.
