Internet MIS security technology includes mainly: Authentication, Encryption, Access Control, Auditing and so on. Role-based access control (RBAC) is an access control method that has been widely used in Internet, operation system and relation database many years. Though RBAC is already relatively mature in the above fields, new problems occur when it is used in XML properties. By means of enterprise office automation system (EOA), the enterprise can easily migrate the release of information and communication functions to the Internet, which makes people convenience. The EOA system also provided a combination of enterprise management process reengineering, construction and optimization of the internal management information systems, decision support systems, and office automation systems. The system can get high level technical and advisory support for the management of enterprise information to fulfill the needs of specific business, affairs, and the conferences. This paper introduces EOA system strategy based on role-based access control (RBAC). The system centers in day-to-day office management service, achieves division of authority between different departments and staff through the introduction of data rights and function rights, so as to achieve the office management platform with the coordination of information, management, and service. This paper provides the method of realizing the work flow through RBAC management, the concept of authority is broken down to each operating procedures; realization of user operational procedures are reflected in the achievement of right-matching and right-series, office processes are standardized, the management level and quality are improved; the goal of improving office efficiency is achieved.

GAF: A General Auction Framework for Secure Combinatorial Auctions

<p>Auctions are an economic mechanism for allocating goods to interested parties. There are many methods, each of which is an Auction Protocol. Some protocols are relatively simple such as English and Dutch auctions, but there are also more complicated auctions, for example combinatorial auctions which sell multiple goods at a time, and secure auctions which incorporate security solutions. Corresponding to the large number of protocols, there is a variety of purposes for which protocols are used. Each protocol has different properties and they differ between how applicable they are to a particular domain. In this thesis, the protocols explored are privacy preserving secure combinatorial auctions which are particularly well suited to our target domain of computational grid system resource allocation. In grid resource allocation systems, goods are best sold in sets as bidders value different sets of goods differently. For example, when purchasing CPU cycles, memory is also required but a bidder may additionally require network bandwidth. In untrusted distributed systems such as a publicly accessible grid, security properties are paramount. The type of secure combinatorial auction protocols explored in this thesis are privacy preserving protocols which hide the bid values of losing bidder’s bids. These protocols allow bidders to place bids without fear of private information being leaked. With the large number of permutations of different protocols and configurations, it is difficult to manage the idiosyncrasies of many different protocol implementations within an individual application. This thesis proposes a specification, design, and implementation for a General Auction Framework (GAF). GAF provides a consistent method of implementing different types of auction protocols from the standard English auction through to the more complicated combinatorial and secure auctions. The benefit of using GAF is the ability to easily leverage multiple protocols within a single application due to the consistent specification of protocol construction. The framework has be tested with three different protocols: the Secure Polynomial auction protocol, the Secure Homomorphic auction protocol and the Secure Garbled Circuits auction protocol. These three protocols and a statistics collecting application is a proof of concept for the framework and provides the beginning of an analysis designed at determining suitable protocol candidates for grid systems.</p>
