基于工业联盟链的物联网可信认证优化方法OA

Industrial Internet of Things devices are deployed in different network environments,and a large amount of data is distributed and stored in edge nodes,resulting in problems such as data information fragmentation,poor trust transfer,and transmission delay.In view of this situation,a low-latency trusted authentication mechanism based on consortium chain distribution scenarios is proposed,which uses the characteristics of consortium blockchain to realize secure credit authentication of distributed data under the edge computing network architecture,and reduces the time overhead of the authentication process by optimizing the maximum hit rate cache algorithm.Experimental results show that the cache efficiency of this scheme is greatly improved compared with traditional algorithms,and it has good security and high efficiency for trusted authentication in distributed scenarios.
