Abstract

The invention relates to an Internet of Things data storage and equipment access control method based on a Fabric block chain, which belongs to the technical field of Internet of Things. The method comprises the steps of S1 selecting a plurality of block chain nodes to build a Fabric block chain network; S2 networking Internet of Things devices of different organizations through a wireless sensornetwork; S3 introducing a management center to respectively represent different organizations of Internet of Things devices to interact with the alliance chain network; S4 deploying a chain code compiled by business logics agreed among a plurality of different organizations at a peer node by utilizing the multi-channel characteristic of the alliance chain, and instantiating the chain code; and S5storing the Internet of Things data in a management center, enabling the management center to perform grouped hash calculation on the stored Internet of Things data, and storing hash values in non-leaf nodes of the Merkle tree, wherein only the root hash value in the root node of the Merkle tree written into the Fabric alliance block chain becomes unique voucher for subsequent query and verification of authenticity of original data..

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and relates to an Internet of Things data storage and device access control method based on Fabric block chain. Background technique [0002] When traditional access control is centralized and applied to the Internet of Things, with the rapid growth of Internet of Things devices, it may lead to a single point of failure, which may cause privacy leakage and other issues, and bring new security risks and challenges to the Internet of Things system. Data Security issues are becoming more and more important. Access control is one of the important technologies to ensure secure data. Traditional access control technologies, such as identity-based access control (IBAC), discretionary access control (DAC), etc. are not suitable for implementing access control in IoT systems, because due to a large number of unknown identities , it is nearly impossible to create access control lists (ACLs)...
