Trusted system suitable for sensing computing layer of industrial Internet of Things

Abstract

The invention provides a trusted system suitable for an industrial Internet of Things sensing computing layer, comprising a cache unit configured to be connected with an association unit and used for temporarily storing pre-detection information; the strategy library is configured to be connected with the association unit and used for storing association strategies; the association unit is configured to be connected with the acquisition end, the strategy library and the cache unit, and is used for receiving the post-detection information of the acquisition end, associating the pre-cached pre-detection information and the newly detected post-detection information into transmission information according to an association strategy of the strategy library, and transmitting the transmission information to the acquisition end; and caching the later detection information as the previous detection information of the next group of detection information. According to the invention, the prior detection information and the later detection information are associated into the transmission information to be sent, so that the prior received detection information can be verified, the cracking difficulty in the transmission process can be improved, the operation efficiency of the receiving end can be improved, and the method has the advantages of safety in use and high credibility.

Problems solved by technology

[0003] The Internet of Things uses various sensors as sensing terminals to collect information, and then transmit and process it. The large-scale thing-to-thing connection network has a large number of scattered sensing nodes, which are easy to become the attack target of information data and bring a lot of information. safe question

At present, the credible way of IoT sensory computing mostly adopts encryption algorithm to encrypt and transmit the collected data. However, due to the large number of sensory nodes and their dispersal, when the encryption algorithm is more complex, a large amount of real-time data will make the calculation pressure of the receiving end greater, and The general encryption algorithm is easy to be cracked, and it is difficult to guarantee the security of transmission.
