Anonymous IoT Data Storage and Transaction Protocol Based on Blockchain and Edge Computing

摘要

This paper proposes a distributed data anonymous storage and transaction protocol that discards the centralized architecture and distributes the computational pressure to each edge device through blockchain and edge computing. In addition, a pseudo-identity-based data anonymous storage scheme is designed based on ElGamal cryptosystem, and the anonymous transaction scheme based on ECDLP and blinding signature allows sellers and buyers to directly trade through the blockchain. The protocol proposed in this paper effectively guarantees the security of data storage and the anonymity of data transactions.
