The ABAM introduces an agent to keep the negotiation process with no human intervention. Meanwhile, the ABAM specifies the format of a meta access control policy, and adopts credentials with flexible format to meet the requirements of access control policies instead of disclosing the whole contents of a certificate. Furthermore, the ABAM uses asymmetric functions with a high security intensity to encrypt the transmitting message, which can prevent information from being attacked. Finally, the ABAM presents a new negotiation protocol to guide the negotiation process. A use case is studied to illuminate that the ABAM is sound and reasonable. Compared with the existing work, the intelligence, privacy and negotiation efficiency are improved in the ABAM.展开更多

With the rapid development of computation and communication technologies, loV promises huge commercial interest and research value, thereby attracting a large number of companies and researchers. This paper proposes an abstract network model of the IoV, discusses the technologies required to create the IoV, presents different applications based on certain currently existing technologies, provides several open research challenges and describes essential future research in the area of loV.展开更多

As the ＂core＂ of enterprises, the financial industry has undergone great changes also, and the mode of traditional accounting in manual has been replaced by a computerized accounting. A computer can do all the financial work from accounting to reporting. Efficient and convenient accounting work allows financial personnel have more energy and time in enterprise management and decision-making, and the core of financial work has shifted to management. Therefore, more and more enterprises realize management accounting＇s value and importance. Management accounting includes information collection, analysis, storage and transfer, as well as data processing and analysis, making information system essential. Thus, management accounting information system will be an indispensable tool for enterprise value management. In the study, based on management accounting information, application of management accounting information in mid and large-size enterprises in China was reviewed to analyze existing problems and propose countermeasures with consideration of financial cloud model and business intelligence.展开更多

This paper analyzes the franchise value change information of state-owned commercial bank. The franchise value change information shows that the franchise value of state-owned Commercial Bank is descending. Along with the descending of the franchise value, state-owned commercial bank strengthens its high risk investment motive when it chooses its investment strategy. State-owned commercial bank tends to run the high risk of investing securities because its investment variety is very sparse. Based on the theoretical principle of how to control securities investment risk, this paper proposes some countermeasures and suggestions that state-owned commercial bank strengthen the control of its securities investment risk in order to perfect its investment strategy.展开更多
