Device cross-domain authentication management method and device based on block chain

Abstract

The invention discloses an equipment cross-domain authentication management method and device based on a block chain, electronic equipment and a storage medium, and the method comprises the steps: adding a plurality of institution management departments into an institution alliance committee according to a voting mechanism; updating Merkel tree root values in a plurality of institution management departments, and storing the Merkel tree root values to the smart contract; when a lending device request is made and a lender determines that a device lending condition is satisfied according to the generated device Merkel tree proof and a Merkel tree root value in the smart contract, the two parties sign a transaction and upload the transaction to the block chain while performing device handover by using the gate controllers of the two parties, and a local state is updated; and when the borrowed device is returned, the returning party generates a device Merkel tree proof, the two parties sign a transaction and upload the transaction to the block chain while performing device handover by using the gate controllers of the two parties, and the local state is updated. The device cross-domain management has security and expandability, various threats and attacks can be prevented, and privacy data of users and devices are protected from being leaked.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular to a blockchain-based device cross-domain authentication management method, device, electronic device, and storage medium. Background technique [0002] In the Internet of Things and many fields, there are a large number of devices, and there are devices and resources shared among different enterprises and organizations. In this scenario, cross-domain authentication management of devices is required. [0003] In the process of device exchange, sharing, and management, there are many problems to be solved, such as access control, identity authentication device tracking, etc. In addition, most devices contain sensitive and private data of many enterprises or users. Once the data is lost, it will cause huge economic losses to the relevant enterprises and lead to very bad consequences. Therefore, a secure device management solution is very necessary to preve...
