Abstract

This paper present a novel blockchain CP-ABE (Ciphertext-Policy Attribute-Based Encryption) data ciphertext sharing scheme, leveraging decentralized proxy re-encryption. It utilizes Ethereum blockchain and zero-knowledge proof technologies to develop a blockchain key management system for multiparty secure computation. This system aims to mitigate heavy computation and key leakage risks associated with traditional centralized CP-ABE systems. The approach begins with the design of a distributed master key generation and distribution protocol within the data ciphertext access control, deploying the UMBRAL-based proxy re-encryption technology on blockchain for key management system. Moreover, the paper uses ERC1155 to mint transferable NFTs for blockchain transactions in data sharing and access control. Through simulation experiments, our scheme demonstrates improved scalability in blockchain ciphertext data transactions and storage, alongside a significant decrease in the Gas costs of on-chain data asset transactions. Furthermore, our methodology not only augments the safety of distributed key management but also realizes high computational efficiency and swift query response, particularly in scenarios of high concurrency.
