Wireless sensor networks are becoming an important facilitator for the Internet of Things. These embedded devices can harvest different types of information such as temperature, pressure and humidity, which offer important data for making decisions regarding various applications such as healthcare, logistics and smart homes. Different sensors working together act as a local sensor network. With the advent of the new 6LowPan standard the sensor nodes can even participate in Internet communications, opening up even more possibilities. The downside is that these networks are more prone to intrusion by unwanted parties. Furthermore implementing security is not straightforward due to the constrained nature of the sensor nodes, although different solutions have been proposed. One of the remaining and most challenging issues is the key management problem. In this paper, we propose a symmetric key management scheme for wireless sensor networks that uses tamper-proof hardware for key generation and distribution. The scheme requires no deployment knowledge before enrolling and makes use of a trusted central entity for key negotiation to provide end-to-end security. Our implementation and evaluation were performed on the tiny Zolertia Z1 hardware platform, running Contiki-OS.

“…Establishing symmetric keys in WSNs is a challenging task due to the limited resources of sensor nodes [Yüksel et al 2011;Perrig et al 2004]. Specifically, the limited computational and memory constraints of sensors prohibit using public keys to establish pairwise symmetric keys, or just to predistribute on each node symmetric keys with all other nodes in the network.…”

Node-Capture Resilient Key Establishment in Sensor Networks: Design Space and New Protocols

Key management is required for basic security services of confidentiality, integrity, and data source authentication. Wireless sensor networks (WSNs) are a challenging environment to provide such services due to the resource constraints and the increased likelihood of nodes to be captured. Various key management techniques were proposed that trade off resilience to node capture and overhead in terms of communication and memory.We identify the main factors influencing the design space of key management protocols for sensor networks and describe representative protocols that trade off the number of links established, communication overhead, and resilience to node capture. These trade-offs are due to using direct, pathbased, or multipathbased communication to establish secure links. We propose a new multipath protocol relying on an encoding scheme tailored for WSNs and analyze the effects of key pre-distribution on multipath key establishment.We provide extensive simulations to understand the trade-offs between resilience to node compromise and communication overhead under numerous network scenarios. This comparison highlights the tradeoffs between these vastly different key management schemes. For the newer class of key management schemes-multipath based-we quantify experimentally the additional communication overhead required for extra paths and the improvement in resilience from using these paths. . 2014.
