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.

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
