Brief Announcement: Providing End-to-End Secure Communication in Low-Power Wide Area Networks
Recent technologies for low-rate, long-range transmission in unlicensed sub-GHz frequency bands enables the realization of Long-range Wide Area Network. Despite the rapid uptake of LPWANs, security concerns arising from the open architecture and usage of the unlicensed band are also growing. While the current LPWAN deployments include basic techniques to deal with end-to-end encryption there are specific security issues that arise due to the overall architecture and protocol layer design. In this paper, a new scheme to establish end-to-end secure communication in long-range IoT deployments is introduced. The advantages over the existing approaches and architectural design are presented in the context of typical smart cities application scenarios.
