Due to recent notorious security threats, like Mirai-botnet, it is challenging to perform efficient data communication and routing in low power and lossy networks (LLNs) such as Internet of Things (IoT), in which huge data collection and processing are predictable. The Routing Protocol for low power and Lossy networks (RPL) is recently standardized as a routing protocol for LLNs. However, the lack of scalability and the vulnerabilities towards various security threats still pose a significant challenge in the broader adoption of RPL in LLNs.To address these challenges, we propose SPLIT, a secure and scalable RPL routing protocol for IoT networks. SPLIT effectively uses a lightweight remote attestation technique to ensure software integrity of network nodes. To avoid additional overhead caused by attestation messages, SPLIT piggybacks attestation process on the RPL's control messages. Thus, SPLIT enjoys the low energy consumption and scalability features of RPL protocol, which are essential in resource-constrained large scale networks such as IoT. The simulation results for different IoT scenarios show the effectiveness of SPLIT compared to the state-of-the-art in presence of different types of attacks, concerning metrics such as packet delivery ratio and energy consumption.

Abstract

Due to recent notorious security threats, like Mirai-botnet, it is challenging to perform efficient data communication and routing in low power and lossy networks (LLNs) such as Internet of Things (IoT), in which huge data collection and processing are predictable. The Routing Protocol for low power and Lossy networks (RPL) is recently standardized as a routing protocol for LLNs. However, the lack of scalability and the vulnerabilities towards various security threats still pose a significant challenge in the broader adoption of RPL in LLNs.To address these challenges, we propose SPLIT, a secure and scalable RPL routing protocol for IoT networks. SPLIT effectively uses a lightweight remote attestation technique to ensure software integrity of network nodes. To avoid additional overhead caused by attestation messages, SPLIT piggybacks attestation process on the RPL's control messages. Thus, SPLIT enjoys the low energy consumption and scalability features of RPL protocol, which are essential in resource-constrained large scale networks such as IoT. The simulation results for different IoT scenarios show the effectiveness of SPLIT compared to the state-of-the-art in presence of different types of attacks, concerning metrics such as packet delivery ratio and energy consumption.
