A new construction of the anonymous identity-based encryption is proposed. The new scheme has the exciting features over the availables, such as short public keys and private keys, constant size ciphertexts and low computation cost. In addition, the proposed scheme is constructed based on the dual system encryption, which is relatively simple to get adaptive security. In the standard model, the security of our scheme is reduced to the static assumptions instead of other strong assumptions. © ICIC International 2011.

Currently, with the evolution of virtualization technology, cloud computing mode has become more and more popular. However, people still concern the issues of the runtime integrity and data security of cloud computing platform, as well as the service efficiency on such computing platform. At the same time, according to our knowledge, the design theory of the trusted virtual computing environment and its core system software for such network-based computing platform is at the exploratory stage. In this paper, we believe that efficiency and isolation are the two key proprieties of the trusted virtual computing environment. To guarantee these two proprieties, based on the design principle of splitting, customizing, reconstructing, and isolation-based enhancing to the platform, we introduce TRainbow, a novel trusted virtual computing platform developing by our research *** the two creative mechanisms, that is, capacity flowing amongst VMs and VM-based kernel reconstructing, TRainbow provides great improvements (up to 42%) in service performance and isolated reliable computing environment for Internet-oriented, large-scale, concurrent services.

security assessment of Thermal Power Plants (TPPs) is one of the important means to guarantee the safety of production in thermal power production enterprises. Essentially, the evaluation of power plant systems relies to a large extent on the knowledge and length of experience of the experts. Therefore in this domain Case-Based Reasoning (CBR) is introduced for the security assessment of TPPs since this methodology models expertise through experience management. Taking the management system of TPPs as breakthrough point, this paper presents a case-based approach for the security assessment decision support of TPPs (SATPP). First, this paper reviews commonly used approaches for TPPs security assessment and the current general evaluation process of TPPs security assessment. Then a framework for the Management system security Assessment of Thermal Power Plants (MSSATPP) is constructed and an Intelligent Decision Support system for MSSATPP (IDSS-MSSATPP) is functionally designed. MSSATPP involves several key technologies and methods such as knowledge representation and case matching.

Network emulation environment is great importance to the research of network protocols, applications and security mechanism. Large-scale network topology generation is one of key technologies to construct network emulation environment. In this paper, a new large-scale network topology generation framework called LSNTGF is proposed, which divides the network topology into three hierarchies: AS, router and terminal node. It contains the assignment mechanism to bandwidth of each link and IP address of each node. The framework is evaluate by implementation, and the result illustrate it is efficient to network emulation environment for network protocols and security research. © 2010 IEEE.

The scene of surveillance video is usually wide and variable, and the target vehicles inside it are often small. Surveillance videos usually are not suitable for intelligent video applications, such as video vehicle detection. To solve this problem, an extraction method of road structure for surveillance video is proposed for intelligent applications. The principle of the method is developed to first extract road regions of surveillance videos by accumulating movement regions in video image sequences. Based on it, the left and right borderlines of road regions are pulled out using the Hough transform according to the statistical characteristics of road structure in surveillance video. Experiment results have shown that the road structure can be extracted precisely and effectively from the surveillance video of freeway and city expressway. © 2011 ASCE.

As 3G networks provide enhanced capabilities of data transportation, a considerable amount of mobile applications and services, which involve mass of unstructured digital contents, e.g., video and audio, are available. Meanwhile, pirate and illegal distribution of these digital contents are severe issues. Digital Rights Management (DRM) aims at protecting unstructured digital contents from being abused through regulating the usage of digital contents. However, existing mobile DRM schemes more or less suffer from poor compatibility, bad practicality or high cost. Besides, to the best of our knowledge, fewer of these DRM schemes concern efficient unstructured data management in the DRM backend (servers and systems) based on Cloud Computing. In this paper, we propose Phosphor, a cloud based mobile DRM scheme with sim card. In details, an unstructured data management system is adopted for efficient data management services in DRM backend . Meanwhile, sim card is introduced to Phosphor, which not only reduces the cost, but also provides higher *** have implemented our DRM scheme, which demonstrates that Phosphor is efficient, secure and practicable. © 2010 IEEE.

The worm experimental environment is the pivotal foundation for the worm research. Existing methods to build the environment can be classified into three categories: mathematical modeling, simulation and emulation. However, almost all of the existing methods inherently face a rigid fidelity-scalability tradeoff problem. Aming at this issue, this paper proposes a novel virtual-reality hybrid worm emulation model, which integrated the packet-level simulation and network emulation method to build worm experimental environment, for analyzing the behavior of worm propagation with respect to the changes of the network and worm characteristics. With the experiments, we analyze the impacts, induced by the network and worm characteristics on the worm propagation. The results indicate that our experimental environment can provide great support for the worm research. © 2010 IEEE.

An adaptive strategy was proposed for EH system. Modules of attack detection, feedback transmission and adaptive control were added to original EH system. They could help to make threats analysis and adjust hopping strategy in real time, so as to reduce the probability of the system stepping into the attackers' target area. With the experiments proving the anti-attack ability of the prototype system, the feasibility and effectiveness of adaptive strategy were demonstrated for EH system.

IGES is a widely used standard for mechanical data exchange. In this paper, we present a new method for the retrieval task of IGES surface model. Based on this method, a novel distinctive face selection strategy is proposed and evaluated. In the training database, each model is treated as a set of disordered faces, and their features are extracted and stored respectively. The Discounted Cumulative Gain (DCG) value of each face is then calculated and stored for later utilization. To retrieve models in the testing database, we first forecast each face's DCG value by searching its most similar face's DCG value in training database, and then the top k faces with highest forecasted DCGs are selected as query input. A greedy algorithm is finally applied to get the total similarity. Experimental results show that our algorithm is superior or at least comparable to some of the most powerful methods in finding parts with similar functionality in most cases. © 2010 IEEE.
