EBCC: Enclave-Backed Confidential Containers via OCI-Compatible Runtime Integration

Di Lu, Jianfeng Ma, Qingwen Zhang, Xuewen Dong, Yujia Liu, Yulong Shen, Zhiquan Liu

EBCC lets TEE-backed confidential containers follow the standard OCI lifecycle without enlarging the protected TCB.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

EBCC can make TEE-backed execution manageable through an OCI-style lifecycle without materially enlarging the protected-side TCB.

C2weakest assumption

The backend adapter and lifecycle mediation preserve isolation and do not introduce new attack surfaces or require post-hoc security assumptions beyond standard TEE guarantees.

C3one line summary

EBCC provides an OCI-compatible runtime architecture that unifies REE and TEE stages for confidential containers while preserving standard lifecycle operations behind a backend adapter.
