摘要

The security of Internet of Things (IoT) devices' sampled data in Agriculture is important as any malicious tampering or destroy may lead to wrong decision making and causes immeasurable losses. On the other hand, the emerging blockchain technology provides safer solutions in data protection and retracing. Yet when blockchain technology applied in agricultural data tracking and storage, the identity based searching is long and difficult. Also, public blockchain or consortium blockchain technology along cannot provide satisfactory solutions balancing between safety and high system performance. In this paper, we propose an Inter Planetary File System (IPFS) storage based double-blockchain solution for agricultural sampled data protection in IoT network. We use IPFS network to store the content of sampled data; the proposed system can retrieve the complete data segment by oracle mechanism. Then we design a consortium blockchain, Agricultural Sample Data Chain (ASDC), based on Ethereum technology and improve Merkle Patricia Trie (MPT) based account for every category of sampled data. Finally, after the data are stored in blocks in ASDC, block hash will be generated and upload on main chain of Ethereum to keep a public record in case malicious attacks occurs. Simulated results show that our proposed method has smaller time consumption than cloud storage and blockchain only storage; as well as our system is more robust than other two systems.
