Ad hoc and sensor networks are fast becoming an integral part of information and computing systems. A sensor network consists of small, programmable elements that is in a variety of applications including battlefield, infrastructure protection, surveillance and medical monitoring, and finer data collection (e.g., in an sporting event). Sensors usually have limited power supplies, small memory sizes land low communication range.
Securing sensor networks presents many challenges nges resulting from the ease of capturing and tampering with them, and their processing limitations that makes implementation of strong security measures not possible.
Radio Frequency IDentification (RFID) tags are seen to become the most numerous computing device in near future. RFIDs provide many challenges to not only security of data but also privacy of individuals.
In sensor networks we work on application of cryptographic and non-cryptographic techniques for providing security, and also design of intrusion detection systems to detect mis-behaving nodes. Of high is modeling security properties of RFIDs and design of systems with provable security that achieve the stated requirements.
