Secure fusion approach for the Internet of Things in smart autonomous multi-robot systems

Abstract The application of smart autonomous multi-robot systems has received increasing attention and dramatically developed, and this situation greatly promotes the development of the Internet of Things (IoT) and brings the IoT into a new stage. However, the IoT has some emerging issues, such as security and privacy; among many concerns, trusted identity authentication and consensus protocols are the main ones. To address these issues, this study proposes a novel scheme for the identity authentication and consensus algorithm . In the proposed scheme, an identity-based authentication model is designed, and all communication nodes utilize this model to establish connection and conduct data exchange. Meanwhile, a hash pool-based joint consensus algorithm is constructed. All transmission data are strictly protected by permuting hash functions from hash pool and utilizing the generated random number. This feature greatly enhances the security for the IoT. Analysis and experimental results demonstrate that the proposed scheme provides enhanced security and reliability for the IoT. Furthermore, the time efficiency is encouraging, and the communication and storage cost is promising.
