Abstract: This paper proposes a method based on dynamic storage chain to overcome the problem of large amount of data in the internet of things (IOT). In this method, ECC and D-H are used as encryption tools of the whole architecture to realise encrypted communication between lot devices. Combined with the blockchain technology, the IOT node access and the IOT dynamic data are stored to promote the dynamic data between IOT nodes to be stored in the offline storage structure, so as to achieve the purpose of secure storage of IOT dynamic data. The experimental results show that the average data storage time is 0.40 s, the maximum root mean square error is 0.06, and the cost is controlled within 34,500 yuan, which can effectively realise the security of IOT nodes.

Keywords: blockchain; IOT; internet of things; dynamic data; security storage; dynamic storage chain; ECC; D-H.
