TLoRa: Implementing TLS Over LoRa for Secure HTTP Communication in IoT
Atonu Ghosh, Akhilesh Mohanasundaram, Srishivanth R F, Sudip Mis · 2025-10-03 · via cs.CR updates on arXiv.org

We present TLoRa, an end-to-end architecture for HTTPS communication over LoRa by integrating TCP tunneling and a complete TLS 1.3 handshake. It enables a seamless and secure communication channel between WiFi-enabled end devices and the Internet over LoRa using an End Hub (EH) and a Net Relay (NR). The EH tethers a WiFi hotspot and a captive portal for user devices to connect and request URLs. The EH forwards the requested URLs to the NR using a secure tunnel over LoRa. The NR, which acts as a server-side proxy, receives and resolves the request from the Internet-based server. It then relays back the encrypted response from the server over the same secure tunnel. TLoRa operates in three phases -session setup, secure tunneling, and rendering. In the first phase, it manages the TCP socket and initiates the TLS handshake. In the second, it creates a secure tunnel and transfers encrypted TLS data over LoRa. Finally, it delivers the URL content to the user. TLoRa also implements a lightweight TLS record reassembly layer and a queuing mechanism for session multiplexing. We evaluate TLoRa on real hardware using multiple accesses to a web API. Results indicate that it provides a practical solution by successfully establishing a TLS session over LoRa in 9.9 seconds and takes 3.58 seconds to fulfill API requests. To the best of our knowledge, this is the first work to comprehensively design, implement, and evaluate the performance of HTTPS access over LoRa using full TLS.
