TEE-Based Mutual Proofs of Transmission Services in Decentralized Systems
Lifeng Liu, Jian Li, Tim Tingqiu Yuan · 2020
We propose a scalable and verifiable transmission recording system based on trusted execution environment (TEE) to support payment system for decentralized services. In the proposed system, consensus of the service is reached based on the service recording chains via mutual recording among participating nodes of the service; A simplified Merkle tree structure is used in the service records for checking the integrity of the transmission content, which facilitates efficient re-transmission of lost packets among neighboring nodes, and tracking of multi-path transmissions. The proposed system enables efficient and trusted incentive mechanisms to support network transmission services via edge devices (mobile devices, moving connected vehicles, base stations, etc.) in dynamic and self-organizing networks.
