Security in Wireless Sensor Networks (WSNs) is commonly bootstrapped by cryptographic key distribution among nodes. In this scenario, one of the greatest research challenges is to ensure secure keys storage by sensors due to their constrained resources and major exposure to tampering attempts. The main contribution of this work is to propose and analyze a mechanism for secure symmetric key distribution...
The EU funded ANGEL project focuses on the development and deployment of wireless sensor networks building ambient intelligence systems for assisted-living and personal health monitoring. The provision of security services such as confidentiality and authentication is a fundamental requirement for ANGEL in order to ensure the safety and privacy of the users; the technical realization is challenging...
