Abstract
As a typical representative of a new generation military information technology, the value and significance of Internet of Battlefield Things (IoBT) has been widely recognized by the world's military forces. At the same time, Internet of Battlefield Things (IoBT) is facing serious scalability and security challenges. This paper presents the basic concept and six-domain model of IoBT, explains the integration security framework of IoBT and blockchain. Furthermore, we design and build a novel IoT framework called IoBTChain based on blockchain and smart contracts, which adopts a credit-based resource management system to control the amount of resources that an IoBT device can obtain from a cloud server based on pre-defined priority rules, application types, and behavior history. We illustrate the deployment procedure of blockchain and smart contracts, the device registration procedure on blockchain, the IoBT behavior regulation workflow and the pricing-based resource allocation algorithm.
