Dynamic strategy-based security Kernel is very important in an embedded system. It is the core of a secure computing environment that can be implemented in the form of a hardware component installed in a computer or network topology, a software implementation, or a firmware system installed in a computer microchip, or in an embedded system. With increasing dependence on embedded systems, their reliability and security become more and more of an issue. This paper designs and develops a security Kernel prototype system which is named as SK-I. This prototype is very generic since it could be easily inserted to other systems or platforms. It is based on the safety identification, access control, user authority verification, and authority mechanisms. SK-I has been tested under difference dimensions so that the functionalities and performance are examined. From the testing, it is observed that create and delete operation costs a lot and the decision buffer plays an important role in enhancing the performance of an embedded system.

This paper discusses the performance curves analysis based on stochastic network calculus under the diversified requirements from different applications in network. Such requirements need different quality of service (QoS), one of which is performance curve analysis. This paper proposes a theory model to investigate the performance curves in SNC. This model integrates the probability calculation into performance analysis model so as to present and analyze the statistical reuse characteristic of data stream over the Internet. The QoS model combines the above two analysis curves without using the min-plus algebra in order to avoid the noncooperation caused by Prb-MinPlus. Several innovations are included in this model. Firstly, the arrival curve indicates the stochastic data steam in the network by integrating the probability functions. Thus, the data stream is able to reflect the current situation in a network. Secondly, the model proposed in this paper integrates arrival curve and service curve to build up the model. As a result, the performance analysis could be carried out more precise. Thirdly, the proposed model has been compared with Jiang-SNC in terms of probability upper boundary and overall performance. It is observed that, the proposed model outperforms Jiang-SNC in QoS and can avoid the problem of Prb-MinPlus. © 2014 SERSC.

The study of the logistics system mode based on the city construction is mainly according to the concrete characteristics of the logistics operation, to sum up the characteristics of the logistics system in the area of the set of the logistics information system, which aims to design a reasonable response model framework of the logistics system. This research is mainly based on the research on the GPS system, and deepening the logistics information system is to design and construct the function combination of the countermeasures of the logistics information technology, which is to design a complete system framework of the working state. In addition to the related GIS technology, and the implementation of the monitoring and the control of the logistics information system, and the implementation of the navigation guidance in a reasonable range, provide the reference for the construction plan of the whole system, which lays a theoretical foundation for the healthy and effective operation of the countermeasures of the logistics information technology. © (2014) Trans Tech Publications, Switzerland.
