We propose a novel authentication method based on sparse representation for the reconciliation in physical layer key Generation. In order to protect the legitimation of the channel, sparse representation is considered to enhance wireless security by using the unique channel location information. In contrast to traditional approaches, in this paper, we consider that this reconciliation channel is unauthentic,...
Trust management has an important significance on the reliable operation and safety guarantee in Wireless Sensor Networks(WSNs). Previous works were implemented by exchanging key among neighboring sensors. Considering that in many cases, the sensor nodes' behavior is both spatio-temporal correlated, and this paper proposes a reputation model called BRMSN (Behavior Reputation Method for Sensor Networks)...
In wireless sensor networks (WSNs), secure data aggregation is an important application. Previous works are implemented by authentication among neighboring sensors. Considering that in many cases, data aggregation is both spatial and temporal correlation, this paper proposes a distributed and localized secure data aggregation algorithm based on behavior trust (BTDA). The security and reliability of...
The next generation of wireless networks, as envisioned by recent advances in cognitive radio (CR) technologies, will be intelligently adjust their configuration to changes in the communication environment. Reconfigurability is set to be an important facet in the evolving world of mobile and wireless communications, through which technologies such as cognitive radio are greatly facilitated. In next...
