Currently, NFC security authentication solutions widely use third-party authentication platforms, but their high cost and power consumption are not conducive to popularize NFC technology. To solve this problem, this paper presents a security authentication algorithm entirely based on a Hash function. It is an independent and complete algorithm without the aid of third-party certification platform...
Base distributed database technology has been widely used in missive data processing. The problem of the efficiency of multi-dimensional data query which is caused by its single primary key indexing becomes more apparent. This paper proposed and implemented a multi-dimensional query method based on Hilbert space-filling curve. Using the Hilbert space filling curve to make the multi-dimensional data...
Grids must ensure that the systems they operate not only provide all relevant services, but also meet the users' performance expectations. The paper proposes a novel performance modeling methodology based on Queueing Petri Nets (QPNs) for large-scale heterogeneous distributed systems, with an emphasis on enterprise Grid environment. A hierarchical structure of enterprise grid system and the concept...
Service-oriented architecture (SOA) is an ideal solution to build application system with low cost and high efficiency, but fault detection is not supported in most SOA-based applications. Based on Gauss distribution, a fault detection mechanism for SOA-based applications is proposed. The fault in SOA can be detected through comparing the calculated confidence interval with the predefined parameters...
To face the challenges resulting from increasing complexity of portable consumer electronics, a dependability framework to improve the availability of application software in runtime is needed. In this paper, a system layer division based on the user event processing is given and faults are classified based on it. A hardware software co-designed application aware framework architecture proposed to...
With the rapid advances in grid technology, grid reliability becomes an issue of increasing practical concern and research attention. However, managing grid reliability is not easy due to the complicated, large-scale and dynamic natures. This paper studies the reliability problem of grid service imposed by software or hardware failures, and presents a new approach to analyze grid service reliability...
The paper introduces the remote control teaching system of central air-conditioning. It designs idea to carry through interactive distant education in remote control teaching system. It expatiates the methods, process and thoughts to accomplish distant education by applying modern education technology and interactive teaching methods. By means of these , the distant teaching and training of central...
A new Web Service construction method is proposed according with the principle of Representation State Transfer (REST) in this paper. Using Resource-Oriented Architecture, how to construct the application with REST characteristics is described step by step. The performance of new Web Service construction method is evaluated and is compared with that of Service-Oriented Architecture (SOA). Analytical...
