Special Issue Information

Dear Colleagues,

Wireless sensor networks (WSNs) are becoming a very popular pervasive technology. They normally consist of many low-cost and low-power devices that can sense the environment, process information, and transmit messages by means of wireless communication. According to their limited resources, WSNs are exposed to many security threads, such as eavesdropping, hardware tampering and false messages injection. Therefore, effective security systems that are compliant with the specific characteristics of a WSN are required.

The majority of security systems for wireless sensor networks are based on symmetric encryption. The main open issue for these approaches concerns the establishment of symmetric keys. Much research in recent years has focused on key distribution and management, and several schemes have been proposed. Most of the current solutions use symmetric cryptography since the communication and computational overheads of public-key cryptography limit their applicability to WSNs.

Among symmetric key approaches, many different strategies have been considered. The purpose of this Special Issue on “Key Management in Wireless Sensor Network” is to explore the most recent and innovative solutions that guarantee security and efficiency.

Redundancy in Key Management for WSNs

Security in wireless sensor networks is commonly based on symmetric encryption and requires key-management systems to establish and exchange secret keys. A constraint that is common to many key-management approaches is an upper bound to the total number of nodes in the network. An example is represented by the schemes based on combinatorial design. These schemes use specific rules for the generation of sets of keys that are distributed to the nodes before deploying the network. The aim of these approaches is to improve the resilience of the network. However, the quantity of data that must be stored by each node is proportional to the number of nodes of the network, so the available memory affects the applicability of these schemes. This paper investigates the opportunity of reducing the storage overhead by distributing the same set of keys to more than one node. In addition, the presence of redundant sets of keys affects the resilience and the security of the network. A careful analysis is conducted to evaluate benefits and drawbacks of redundant key distribution approaches. The results show that the use of redundancy decreases the level of resilience, but it scales well on very large networks. Full article

The LoRaWAN is one of the new low-power wide-area network (LPWAN) standards applied to Internet of Things (IoT) technology. The key features of LPWAN are its low power consumption and long-range coverage. The LoRaWAN 1.1 specification includes a basic security scheme. However, this scheme could be further improved in the aspect of key management. In this paper, LoRaWAN 1.1 security is reviewed, and enhanced LoRaWAN security with a root key update scheme is proposed. The root key update will make cryptoanalysis of security keys in LoRaWAN more difficult. The analysis and simulation show that the proposed root key update scheme requires fewer computing resources compared with other key derivation schemes, including the scheme used in the LoRaWAN session key update. The results also show the key generated in the proposed scheme has a high degree of randomness, which is a basic requirement for a security key. Full article
