Abstract

The Internet of things (IoT) has come into widespread use, and data protection and integrity are critical for connected IoT devices in order to maintain security and privacy. Low-power wide-area (LPWA) technologies for IoT wireless communication achieve data protection and integrity by using encryption and message authentication. However, side-channel analysis techniques exist that have the capacity to recover secret information from a device. In this paper, we apply a side-channel analysis technique to the payload encryption process and message authentication code generation process on a real LoRaWAN end-device. The entire AES-128 key for the payload encryption can be recovered with 260 electromagnetic(EM)-leakage traces and 12 bytes of the key for message authentication code generation can be recovered with 140 EM-leakage traces.
