Abstract

The invention relates to a lightweight Internet of things terminal system based on a block chain and a control method thereof. By setting several block chain nodes, at least one Internet of thing terminal node is added to each block chain node, When a security event occurs to any one of the IoT terminals, the corresponding IoT terminal node sends the security event data to the corresponding blocklink node, the block link node receives and updates the distributed accounting book, and the block link node exchanges information between the two nodes to send the security policy to the IoT terminalnode. The invention combines the small storage space of the lightweight Internet of Things terminal and the small storage space of the lightweight Internet of Things terminal, weak computational ability, As that terminal node and the block chain node of the Internet of thing are utilized to form a two-level management, The terminal node of the Internet of Things reports the local threat events and receives the security policy from the node of the block chain. The node of the block chain receives the threat information from the node of the Internet of Things and exchanges the threat information through the technology of the block chain, so that the technology of the block chain can be fully applied in the security scenario of the Internet of Things.

Description

technical field

[0001] The present invention relates to the transmission of digital information, such as the technical field of telegraph communication, in particular to a lightweight Internet of Things terminal system based on blockchain and its control method. Background technique

[0002] With the rapid rise of IoT technology, IoT applications emerge in endlessly. The working process of the traditional IoT security solution is that IoT terminals collect local security events and report them to the central management node. The central management node conducts overall analysis of all intelligence, and after discovering new threats, it issues new threats to all nodes. security strategy.

[0003] For an IoT system, terminal security itself is a very important link. Traditional IoT security solutions cannot guarantee real-time sharing of threat intelligence. More and more organizations have begun to use blockchain technology to discover Threats, for example, each terminal sh...
