SMER: a secure method of exchanging resources in heterogeneous internet of things
- 89 Downloads
The number of IoT (Internet of things) connected devices increases rapidly. These devices have different operation systems and therefore cannot communicate with each other. As a result, the data they collected is limited within their own platform. Besides, IoT devices have very constrained resources like weak MCU (micro control unit) and limited storage. Therefore, they need direct communication method to cooperate with each other, or with the help of nearby devices with rich resources. In this paper, we propose a secure method to exchange resources (SMER) between heterogeneous IoT devices. In order to exchange resources among devices, SMER adopts a compensable mechanism for resource exchange and a series of security mechanisms to ensure the security of resource exchanges. Besides, SMER uses a smart contract based scheme to supervise resource exchange, which guarantees the safety and benefits of IoT devices. We also introduce a prototype system and make a comprehensive discussion.
