Abstract. Ever-growing mobility and ubiquitous wireless Internet access raise the need for secure communication with devices that may be severely constrained in terms of processing...
In this paper we introduce ContikiSec, a secure network layer for wireless sensor networks, designed for the Contiki Operating System. ContikiSec has a configurable design, providi...
Wireless sensor networks (WSNs) are used for various ubiquitous and pervasive environments. A few common applications are security, agriculture, automation, and environmental moni...
Key establishment plays a central role in authentication and encryption in wireless sensor networks, especially when they are mainly deployed in hostile environments. Because of t...
—Achieving secure time-synchronization in wireless sensor networks (WSNs) is a challenging, but very important problem that has not yet been addressed effectively. This paper pro...
