Frontier technologies of trust computing and network security

The special issue of Concurrency And Computation: Practice And Experience includes topics on trusted computing, risk and reputation management, network security and survivable computer systems/networks. These issues have evolved into an active and important area of research and development. Several papers have been accepted for publication in this special issue, which demonstrate novel and original work in this field. The first paper, entitled Dynamic Malicious Node Detection with Semi-supervised Multivariate Classification in Cognitive Wireless Sensor Networks has designed a multivariate classifier to detect malicious nodes in wireless sensor networks.
