Research on Security for Wireless Body Area Network Data in Cloud Storage Based on Blockchain
Yanfang Gao, Lan Yao, MA Yan-song · Journal of Physics Conference Series · 2019
Cloud computing enables users with limited resources to accomplish complex computation. Meanwhile, the massive human body sensing data generated by Wireless Body Area Network (WBAN) can be stored in cloud servers. However, cloud storage of human body sensing data is challenged by some issues. Users need to ensure that cloud servers can return the results and that they are correct. To address this problem, based on the argument system of commitment scheme, this paper designs a DMP verification algorithm. By compiling the hash of the header node into a constraint set and verifying the accuracy of the data of the intermediate node through a hash list, the algorithm reduces the compiling time of the intermediate node and improves the verification efficiency.
