The security of database is more and more concerned. There are several traditional methods to protect the information of databases, such as encryption and authentication. However, these methods are not appropriate for all the situations because of the performance. This paper proposed a new method to prevent the information leakage of traditional databases, and this idea is totally different from the traditional ones. We can change the semantic meanings of relational data by reordering them. By this way, we can prevent the information from leakage. Some users with low privileges will only get the meaningless data, while they do not realize that themselves. In many cases, this method meets the requirements of security while it influences a little on the system performance.
This paper presents a methodology for analyzing quantum information systems, based on model checking;particularly we are interested in the protocol of quantum key distribution B92. It has been proved that this protoco...

Currently there exist dozens of web controller frameworks that are incompatible, but at the same time have large portions of overlapping functionality that is implemented over and over again. Web programmers are facing limitations on code reuse, application and framework integration, extensibility, expressiveness of programming model and productivity. In this paper we propose a minimalistic component model Aranea that is aimed at constructing and integrating server-side web controller frameworks in Java. It allows assembling most of available web programming models out of reusable components and patterns. We also show how to integrate different existing frameworks using Aranea as a common protocol. In its default configuration Aranea supports both developing sophisticated user interfaces using stateful components and nested processes as well as high-performance stateless components. We propose to use this model as a platform for framework development, integration and research. This would allow combining different ideas and avoid reimplementing the same features repeatedly. An open source implementation of Aranea framework together with reusable controls, such as input forms and data lists, and a rendering engine are ready for real-life applications. Copyright 2006 ACM.
