Secure Key Distribution Using Fragmentation and Assimilation in Wireless Sensor and Actor Networks
International Journal of Distributed Sensor Networks, 2015 Secure key distribution is one of the most important building blocks to ensure confidentiality in wireless sensor and actor networks (WSANs). However, the key distribution becomes a challenging task when keys have to be relayed by compromised nodes in ...

Improved Key Distribution and Management in Wireless Sensor Network
Journal of Wireless Communications, 2016 Key set up and distribution in sensor network is a complex task due to inherent limitations in sensor networks. For reducing the “communication and computation overhead” we proposed that the sensor network is partitioned into different zones. Each zone has a separate intrusion detection system (IDS) and key distribution center (KDC).IDS can detect the ...

Implementation of Elliptic Curves in the Polynomial Blom Key Pre-Distribution Scheme for Wireless Sensor Networks and Distributed Ledger Technology [PDF]
Journal of Sensor and Actuator Networks, 2023 One of the challenges in securing wireless sensor networks (WSNs) is the key distribution; that is, a single shared key must first be known to a pair of communicating nodes before they can proceed with the secure encryption and decryption of the data. In

Hierarchical Grid-Based Pairwise Key Pre-distribution in Wireless Sensor Networks [PDF]
, 2008 The security of wireless sensor networks is an active topic of research where both symmetric and asymmetric key cryptography issues have been studied. Due to their computational feasibility on typical sensor nodes, symmetric key algorithms that use the same key to encrypt and decrypt messages have been intensively studied and perfectly deployed in such
