Cross chained aggregated hash token validation system

Abstract

A simplified IoT network validation process includes improvements to enrollment of IoT devices onto the IoT network and authentication of active IoT devices during IoT network operation. A random cipher text is created upon device enrollment and shared to each device in the network. Additionally, a random peer-to-peer cross reference communication pattern is established among the devices. Using a device pairing sequence an iterated (e.g., chained) hash value is generated and stored at the server. During the device authentication, upon basic authentication of the request, a server shares a random point to the network (e.g., a randomly selected IoT device) to trigger the hash token generation process. The network devices perform hash token iteration as a ring. Each IoT device uses the previous hash when generating the next hash. The final hash is sent to the server for validation and comparison against stored keys.
