Keynote Talk 3

Because of the wireless transmission requirement and the self-organizing nature of its architecture for a Wireless and Sensor Network (WSN), the trust management and privacy protection for WSNs have become an especially challenging problem. In this talk, we analyze current threats and attacks in WSNs and survey state-of-the-art trust management and privacy protection schemes in WSNs. Then we classify and describe trust management schemes into two aspects in secure routing and secure data, respectively and privacy protection schemes into data-oriented and context-oriented privacy, respectively. Finally we try to present a clear direction to design and construction of trust mechanisms and privacy protection techniques in WSNs and discuss some interesting and challenging open issues on this topic.
