Abstract

This study proposed a blockchain-based scheme to address issues such as delayed permission revocation, policy leakage, and high proxy re-encryption overhead in supply chain collaboration environments. The method constructed a three-layer security architecture integrating symmetric encryption, attribute-based encryption, and a trusted execution environment(TEE) . It incorporated multi-hop proxy re-encryption to enable dynamic policy updates and forward security for historical data. An IoT event-driven smart contract coordination mechanism was designed to trigger policies automatically and synchronize on-chain and off-chain states. The Groth16 zero-knowledge proof system was integrated with the TEE to form a closed-loop verification system comprising off-chain privacy proofs, on-chain policy auditing, and hardware-controlled decryption. Experimental results demonstrate that the proposed scheme outperforms existing approaches in key metrics such as policy-update latency and decryption response time, effectively supporting fine-grained, verifiable, and lightweight data sharing in scenarios including smart warehousing and cross-border logistics.
