ContikiSec: A Secure Network Layer for Wireless Sensor Networks under the Contiki Operating System

No table of content available

• In this paper we introduce ContikiSec, a secure network layer forwireless sensor networks, designed for the Contiki Operating System. ContikiSechas a configurable design, providing three security modes starting fromconfidentiality and integrity, and expanding to confidentiality, authentication,and integrity. ContikiSec has been designed to balance low energy consumptionand security while conforming to a small memory footprint. Our design wasbased on performance evaluation of existing security primitives and is part ofthe contribution of this paper. Our evaluation was performed in the ModularSensor Board hardware platform for wireless sensor networks, running Contiki.Contiki is an open source, highly portable operating system for wireless sensornetworks (WSN) that is widely used in WSNs.
