Secure routing for internet of things

The Internet of Things (IoT) could be described as the pervasive and global network which aids and provides a system for the monitoring and control of the physical world through the collection, processing and analysis of generated data by IoT sensor devices. It is projected that by 2020 the number of connected devices is estimated to grow exponentially to 50 billion. The main drivers for this growth are our everyday devices such as cars, refrigerators, fans, lights, mobile phones and other operational technologies including the manufacturing infrastructures which are now becoming connected systems across the world. It is apparent that security will pose a fundamental enabling factor for the successful deployment and use of most IoT applications and in particular secure routing among IoT sensor nodes thus, mechanisms need to be designed to provide secure routing communications for devices enabled by the IoT technology. This survey analyzes existing routing protocols and mechanisms to secure routing communications in IoT, as well as the open research issues. We further analyze how existing approaches ensure secure routing in IoT, their weaknesses, threats to secure routing in IoT and the open challenges and strategies for future research work for a better secure IoT routing.

Securing RPL routing protocol from blackhole attacks using a trust-based mechanism

This research addresses blackhole routing attacks —a fundamental security attack on the routing of data in IoT networks. Most IoT devices today, from medical devices to connected vehicles and even smart buildings, come bundled with the capability of communicating wirelessly with one another. Consumers are progressively embracing the concept of connected devices while recent studies indicate that security is not high on the priority list of manufacturers especially in the way these devices route and communicate data amongst themselves thus, leaving the door wide open to attacks and compromises. We propose a trust-based RPL routing protocol, which addresses the blackhole attacks. We show that our proposed system is both secure from blackhole attacks while not imposing undue overheads on network traffic.

A Lightweight Trust Design for IoT Routing

This research proposes a conceptual framework for achieving a secure Internet of Things (IoT) routing that will enforce confidentiality and integrity during the routing process in IoT networks. With billions of IoT devices likely to be interconnected globally, the big issue is how to secure the routing of data in the underlying networks from various forms of attacks. Users will not feel secure if they know their private data could easily be accessed and compromised by unauthorized individuals or machines over the network. It is within this context that we present the design of SecTrust, a lightweight secure trust-based routing framework to identify and isolate common routing attacks in IoT networks. The proposed framework is based on the successful interactions between the IoT sensor nodes, which effectively is a reflection of their trustworthy behavior.

GradeTrust: A secure trust based routing protocol for MANETs

Trust-based secure routing in MANETs has attracted lot of research attention worldwide. It is effective in providing secure routing by isolating malicious nodes and other overheads from MANETs. This paper proposes, GradeTrust, a secure routing protocol for MANETs based on the trust levels of network nodes. It uses trust to isolate black hole routing attacks thus offering secure routing of data traffic as well as improved packet delivery ratio. Preliminary simulation results have shown that trust compromise and packet delivery ratio is better in GradeTrust compared to traditional routing protocols, such as AODV and FSR.
