Trust issue is presently a research hotspot in military information grid. This paper first proposes a SOA-based unified identity authentication scheme, which can transplant the existing account systems into the new one by means of account association, to solve the problem of inter-network identity authentication. Then, this paper develops an asymmetric trust model based on fuzzy logic. This model...
Along with the rapid development of peer-to-peer network technology and the fast increasing number of users, the problems of security in peer-to-peer network is becoming more and more important. By researching the previous trust model of peer-to-peer network, we propose a trust model(PTM) for peer-to-peer networks based on punish mechanism. Firstly, we use the method of social grouping nodes in the...
Worm propagation modeling has been a significant research subject in the Internet-worm research area. An accurate analytical propagation model allows researchers to study the propagation characteristics and traffic pattern of a worm under different set of worm/network parameters, which is often very hard to realize by simulations. More importantly, it gives us an insight into the impact of each worm/network...
The outbreak of worm is very frequent today. It has great impact on the society infrastructure and people's wealth security. A large number of experts have devoted themselves to the research of worm propagation modeling. Both deterministic model and stochastic model have been used in modeling worm spread. In this paper, we analyze the worm functional structure, and then propose a deterministic worm...
The forest fire environment is complex. It is difficult to depict and quantitative analyze the relatives among all elements. The condition of fire scene also becomes more complicated. Everything can't be predicted or recurred. Multi-agent technology provides realizable methods for simulation of forest fire extinguishing with pneumatic extinguisher. In this paper, based on the current situation of...
Active network is a new framework where it not only forwards packets, but also performs customized computation on packets. It provides a programmable interface to users where users dynamically inject services through nodes. This paper discusses the forwarding model and mechanism of message based on active network management model, analyzes the structure and characteristics of this model, and studies...
