Userspsila character analysis and control are important for enterprise network management and security. In this paper, we propose a novel method to classify the userspsila behaviors into different security levels and control their behaviors with corresponding strategies. Firstly, Dflow model and several traffic features, including the number of packets, number of flows, flow durations, etc., are proposed...
According to the limitation of resources in wireless sensor network (WSN), this paper presents a new key pre-distribution scheme based on plane grid. It helps not only to economize the space of storage and keep low consumption, but also ensure that all neighborspsila nodes can establish pair-wise keys directly, however, has a poor safety performance. Then we extend the scheme to three-dimensional...
In this paper, we presented an approach for semantic query based on context approximation of ontology. We also propose a ranking strategy based on ontology context approximation. We exploited the implementation technologies related to the approach. Furthermore, a distributed semantic query system called DSQ was developed for successfully performing tasks of semantic queries across multiple ontologies...
In this paper, we presented an approach for semantic information query based on semantic approximation, where a ranking strategy for answering results is also proposed. We also exploited the implementation technologies related to the approach. Furthermore, a distributed semantic query system called DSQ and experimental results are developed.
