摘要：W ireless sensor network faces several unique challenges. The scale, resource limitations, and new threats such as node capture suggest the use of in - network key generation. The wireless channel itself can be used t o generate information theoretic secure keys. By exchanging sampling messages during device movement, a bit string is derived known only to the two involved entities. Yet, movement is not the only option to generate randomness: the channel response strongl y depends on the signal frequency as well. In this work, we introduce a key generation protocol based on the frequency - selectivity of multipath fading channels. We discuss in this paper how to secure packets in wireless networks
