Abstract: In this paper, combining the existing dynamic access control model based on trust with the dynamic measurement technique, we propose a dynamic access control scheme based on credibility. By the simulation test, the mechanism can prevent the malicious behavior of malicious nodes.

Abstract: Assessment model of the vulnerability for information system is improved by using Bayesian equilibrium algorithm. The mathematical evaluation model of combined complex network information systems is established through the combination of weighted directional algorithm, and the algorithmic routine of network vulnerability assessment is designed. In order to verify the validity and reliability of the model and the algorithm, the test platform of complex network is built, and the vulnerability of network is detected with the weighted directional method, which has got the probability distribution nephogram of network vulnerability and the curve of network performance with time changing. At the last, the effect of different nodes of the network on the vulnerability of system is calculated with directed weights. And the results shown that the attacked number of different nodes and the attacked probability have improved the credibility of information analysis, which has provided theory reference for the research of information system vulnerability.

Abstract: With the development of wireless sensor network, it has been used in water transport. The internet of water transport is come into being and produce much of data information, so data security is necessary as one of its key technologies. This paper puts forward a new trusted architecture for wireless sensor network used in water transport. To guarantee the authenticity and reliability of the data, the concepts of subjective trust elevation and its expected probability is introduced. This model simulation experiments results approve that the model is effective and reliable.

Abstract: Simulation is an important tool for studying the existing and out-coming techniques, and in the meantime there exists disbelief in simulation verification all the time. As credibility is the key in simulation fidelity study, it is important to give an all-round discussion of the credibility of simulation systems themselves. A technique is described for constructing a formalized framework of credibility analysis in simulation systems, on the basis of which the practical method is put forward. The method can be applied to study unexpected or inaccurate simulation results. Following this, the method is applied in a tether-net simulation system to verify the usefulness of the approach proposed. The results of evaluating are discussed.

Abstract: Aiming at nonlinearity in indexes of the combat capability system, based on the comprehensive evaluation of the analysis method of system reliability calculation, improve the system of nonlinear characteristics of structure reliability expression. The method is effective using the example of operation capability of certain reconnaissance intelligence armament system.

Abstract: Twitter has emerged as an ideal platform both for conversation and substantive real-time events, growing considerable concerns whether tweets are credible or not. In this paper, we concentrate on investigating the credibility perceptions of events which would generate abundant activity and significant interconnection on Twitter. We present several methods for crawling tweets set from Twitter according to certain rules. Furthermore, we conduct various experiments for assessing credibility, in which we list affluent categories of features relevant to determining credibility and prominent algorithms to improve the effectiveness for assessing credibility. And then we bring forward some existing imperfection of previous research on information credibility and further look into the future work benefit for assessing credibility precisely.

Abstract: Because of lacking technical and economic theory support, running transformer life assessment work often goes to disorder, thus constructing transformer assessment new model of economic life has a certain practical significance. Because of the transformer serving for a long time and the running environment being complicated, factors that influence the assessment of transformer economic life have a certain characteristic of a variety of coexistence or cross-existence. Due to this characteristic, introduce blind number theory into transformer life assessment, use blind number express evaluation parameter uncertainties, and establish transformer economic life evaluation model. This model not only can get transformer economic life expectancy, but also can obtain economic life interval under different confidence level An example shows that blind number theory applied to the transformer economic life assessment is feasible and effective, which can provide more detailed and diversified information for decision makers and have a certain reference value.

Abstract: The research on design of data fusion with safety credibility is a hot problem in wireless sensor networks. This paper presents a design of wireless sensor data fusion based on reputation, through the combination of data sensing and data fusion detection, it complete the data fusion algorithm and carries out the simulation test to verify the validity of this research.

Abstract: Credibility and integrity has become social system project referring every aspect. Its construction can make hierarchical control and decomposition coordination. Its running mode is through government promotes and supervises, market manipulation, and social public to participation. It should start from goal task of subsystems, including building policy and statute system, services markets system, supervision and reward system, and credit culture system, and finally achieve the advance construction of fiduciary system engineering in the whole society.

Abstract: Multi-QoS and Trusted resource management and Task Scheduling are key problem in cloud computing. This paper presented an effective Multi-QoS and Trusted resource management model and Task Scheduling algorithm in Cloud Computing Environment. By using the idea of fuzzy clustering for reference, the proposed approach can subtly schedule the Cloud tasks to appropriate resources that exactly meets its’ multi-QoS needs of resources. Considering the credibility of cloud resources, the credibility and trusty of task scheduling has been dramatically improved.
