Since the requirements of task cooperation become more complicated and dynamic, the Federated Identity Management (FIdM) should be more safe and flexible to allow and facilitate participating federated organizations, to share information and grant or deny service access requests. Trust is the base of forming federation, and it's a novel idea to establish a security mechanism based on trust for a fair interacting environment. This paper analyzes the various trust needs in the context of FIdM, and designs a common trust model based on multi-dimensional vector which can apply to quantify multi-directional trust. At the end of essay, we present the calculation process of an example and analyze the results.

This paper designs and implements an intelligent projection system which automatically calibrates projected distorted images on an arbitrary surface. It consists of a projector, computer, camera and tilt sensor. Binary-coded structured light is projected to recognize the geometric shape of a projected surface. Tilt sensor determines a appropriate visual angle and an effective projected area. Discrete mapping algorithm is proposed to warp the original projected image which helps to compensate the distortion of a projected surface. The whole process takes less than two minutes. Experimental results show that this intelligent system does not only adapt to the variation of projector pose, but also any arbitrary projected surface automatically.

Web service environment is characterized by its openness and distribution, in which the interacting entities usually have little knowledge about each other and may be in different domains, so the access control for web service has become a challenging problem that needs to be addressed properly. In this paper, an access control policy model based on context and role is proposed that can be appropriate for web service. The model takes context as the center to define and perform access control policies. It uses the contexts of user, environment and resource to execute dynamic roles assignment and constrain the authorization decision. Furthermore, Description Logic is adopted as the policy language to formalize the model. A series of access control policy axioms are defined and the reasoning method is proposed. Experiment result has proved the feasibility and validity of the presented method.

Along with the construction of next generation smart grid, development of the internet of things and appearance of system of systems(henceforth, SOS) warfare based on information systems, the complicated control networks system would confront more and more threat of cyber attack. we design the main structure and key arithmetic of the model, based on the physical electric power infrastructure whose cyber and physical system is close interdependent in order to provide theoretic reference to the analyzing and evaluating the cascading effects from increasing cyber attack to physic system. Preliminary experiments show that these structures and algorithms are reasonable and feasible.

The adaptive interference cancellation is the key factor in DTV based passive radar. The wide band of the DTV signal leads to the high computation burden and the decrease of the cancellation gain. To solve the two problems, an Adaptive filter with Discrete Distribution structure using NLMS algorithm(ADDNLMS) is proposed in this paper, which has better performance compared with the traditional NLMS filter. Moreover, it can adjust the weight structure according to the distribution of the clutters. Simulation and experiment data verification are carried out, which proves the efficiency of the proposed filter.
