Protecting end-device from replay attack on LoRaWAN

In this paper, we propose a method to protect end-device by using RSSI and Hand-Shaking technique using Proprietary Message. One of the frequently used attacks in LoRaWAN is replay attack. It is so easy to sniff packets in a wireless network environment. If an attacker intrudes a service provided by LoRaWAN, the usage pattern of the end-device may be exposed, or a replay attack may cause a problem in connection with the user. To prevent replay attack, LoRaWAN standard uses user identification method by using the value known as DevNonce, but this is not a complete countermeasure. In order to complement these vulnerabilities, we propose a method to protect users by using the physical characteristics of a network called RSSI and a new technique called Proprietary Hand-Shaking.
