Abstract: Nowadays use of E-commerce with mobile devices through the special capabilities, such as mobility and widely used become more popular. The security of transactions in these devices is a great challenge due to limited computing power and relatively weak processors. Mutual authentication and session key agreement can be very influential in term of security. Algorithms introduced in the 1990s had major drawbacks. In the 2000s, a new algorithm based on hash functions were introduced, which had a small computational load, but not a high security and mutual authentication cannot fully support. Algorithms introduced from 2010 onwards due to a combination of hash functions Salt and Nonce are safer. This paper examines the success of the algorithms introduced in this field since 2004 deals.

School of Physics, Tonghua Normal University, Tonghua, China
Abstract: More excellent containment matching model is proposed based on component inclusion matching model. Moreover, matching cost algorithm is analyzed to get inclusive matching model. Representation and retrieval of component are the two main core technologies of reusable software component library. Representation of component facet and corresponding retrieval technology has been widely applied. Among them, both REBOOT and NATO put forward classification scheme of reusable software component. Therefore, efficiency of recall and precision of component are significantly improved comparing with traditional component query situation.

Abstract: In allusion to scientific data isomerism and diversity as well as the lack of semantics in petroleum domain, this paper puts forward ontology-based semantic extraction method for heterogeneous data. Firstly, semantic extraction framework for scientific data in petroleum domain is constructed. On this basis, corresponding semantic transformation and abstract rules are worked out in allusion to structured and semi-structured data to form local domain ontology. Then, overall ontology in petroleum domain of data is constructed through dependence mapping among heterogeneous data. Effective organization and uniform management of heterogeneous data are achieved. Finally, correlation methods are applied in petroleum domain to provide support for effective management of petroleum scientific data and service sharing.

SaaS-Based Campus Smart Card System by Layering Model with Scalability and Configurability and Information Integration
School of Mechatronic Engineering and Automation, Shanghai University, Shanghai, China
Abstract: The smart card system has become an essential part of the digital campus. Recently the solutions based on SaaS in China have become popular for the advantages of less upfront investment, good service quality and convenience maintainability. But in colleges and universities there are many challenges. In this paper, we discussed the solutions for three challenges: personalized demand, system integration and information utilization. Firstly, it was suggested that different users should select the private cloud or public cloud mode. Next, the campus smart card system model based on SaaS was proposed. The model with layered architecture has good configurability, flexibility and integration metrics. Then, several methods were put forward to solve the integration between the card systems with other information systems. In addition, the IA theory was applied in the information retrieval, and the intelligent analysis examples of the card business data were discussed. At last we considered five kinds of configurability: data, function, workflow, portal and smart card, and a configurability management system based on metadata was presented.

School of Control and Computer Engineering, North China Electric Power University, Beijing, China
Abstract: The shape of hybrid monohull at the bow is quite complex and the viscosity force is the main component of the damping force in the drainage area of the bow when the ship moves in waves so that the result of the motion predicition by the traditional potential flow method is very different from the result of experiments. This paper tries to use new numerical compute method considering the effect of the viscosity to improve the precision of the sea keeping predicition. Based on the Reynolds Averaged N-S Equations (RANS) method, the paper takes a hrbrid monohull to compute the hydrodynamic coefficients. According to the result of model test, the prediction of the hybrid monohull’s the longitudinal motion in regular waves at speed of 18kn also indicates that RANS method can reflect viscid influence reducing the motion of hybrid monohull in waves.

Abstract: The high performance digital circuits are designed with the dynamic CMOS circuits. There is different CMOS based digital circuits accepted time by time for improving the driven parameters to get better response. The static CMOS and dynamic CMOS based digital circuits are two common and important technics which employed for designing complex digital circuits. The static CMOS logic based digital circuit gives better noise immunity but slower in response as compare to dynamic CMOS based circuit. In high speed electronics clocked logic methodology plays important role, the clock signal is used to synchronise transistor in sequential logic circuits. Now a day’s dynamic CMOS logic circuits are used to get fast response up to acceptable noise level. In this paper a comparative evaluation is done for different accepted logic circuits based on dynamic CMOS technique. These techniques are Domino Technique, Mendoza Technique, Noise Tolerant Dynamic logic, Feed through logic, Conditional Clocking and Delayed Clocking based on principles such as Using keeper, Pre-charging internal nodes, Raising source voltage, Constructing complementary p-network, and Transparency Window Technique. Circuits designed using dynamic logic styles can be considerably faster and more compact than their static CMOS counterparts. This is especially the case with wide fan-in dynamic logic gates where a single gate can realize the logic function that otherwise would require multiple levels of static CMOS logic gates.
