Today, the B2B E-business systems in most enterprises usually have multiple heterogeneous and independent systems which are based on different platforms and operate in different functional departments. To deal with the increased services in future, an enterprise needs to expand its system continuously. This, however, will cause great inconvenience to the future system maintenance. To implement E-business successfully, a unified internal E-business integration environment must be established to integrate the internal system and thus realize a unified internal mechanism within the enterprise E-business system. The SOA (Service Oriented Architecture) architecture, however, can well meet the above requirements. The integration of SOA- architecture-based applications can reduce the dependency of different types of IT systems, reduce the cost of system maintenance and the complexity of the IT system operation, increase the flexibility of the system deployment, and at the same time exclude the barrier of service innovation. Research and application of SOA-architecture-based enterprise application systems has become a very important research project at present. As an important SOA implementation, Web services is a relatively new technology widely accepted by people. This is because Web services provides a distributed computing method for the heterogene- ous applications integrated in the internet. It can integrate the applications running on the distributed servers which are connected through Intranet, Extranet, and internet together. Based on SOA, this document designs an enterprise E-business application model and realizes a flexible and expandable E-business platform.

The reliability of the distributed system has been an important topic of research. Agreement protocols, which allow the correct nodes to agree on a common value, have been brought up to aid the reliable execution of tasks. In previous works, fully connected networks, generalized connected networks or multicastinge components were proposed to solve the agreement problem. Recently, a new concept of distributed computing, cloud computing, is proposed to provide several services. The cloud computing that can make more application for user from the internet. Unfortunately, existing agreement problem and results cannot cope with the new computing environment and the agreement problem thus needs to be revisited. In this paper, a new protocol is proposed to adapt to the cloud computing environment and derive its bound of allowable faulty components. Copyright © 2009 ACM.

The accuracy of interface description is very important to service composition and dynamic selection of service-oriented systems. It is desirable to describe Web service formally so as to improve the ability of service orchestration. This paper presents a formal interface theory for specifying Web service by extending the existing with the ability to model interface behaviour with transactions at the levels of signature, conversation and protocol. Signature interface and conversation interface model the static invocation relations in Web service interfaces, and protocol interface describes the temporal invocation information. A formal semantics of protocol interface is presented. Based on the semantics, the protocol interface can be transformed into a Labeled Transition System (LTS). Additionally, the compatibility and substitutivity relation conditions between Web services are also proposed.

Addressing some vital security issues in enterprise grid technologies is particularly important from the software industry's viewpoint. Enterprise grid computing systems do face unique security challenges, ranging from preventing access control attacks to ensuring encapsulation and safe object reuse to masquerading and brute-force attacks. Hence, the security requirements for enterprise grid system are also unique. In this paper, we presented the unique security issues and security requirements encountered in enterprise grid systems. We also devise appropriate security policies to address the enterprise grid security requirements.

Software paradigm has been shifted from centralized to decentralized and distributed paradigm. This shift has not only scaled up distribution of software with increasing number of users but brought threats to the software industry with a massive volume of software piracy as well. After software is developed it is subjected to users with contracted rights for use but constrained with modifying, sharing or selling the software. Violation of the said constraints leads to formidable issue of software piracy. distributed computing systems require effective techniques to minimize the piracy impact without degrading the system performance. Software birth marking is one of the effective techniques to minimize the software piracy with guaranteed system performance. It ascertains intrinsic properties in the software program to detect copy of the software. In this paper we propose a dasiamethod basedpsila software birthmark technique targeting the distributed piracy threats. It finds the intrinsic properties in software methods by locating their code attributes, elements, and relation among code elements. The proposed approach not only identifies similarity of programs but detects program transformation as well. Moreover, our technique can spot out method as well as class theft while assuring the credibility and resilience properties of birthmarks.

Anonymity Scheme for Interactive P2P Services

JOURNAL OF internet technology 2009年第3期10卷 299-312页

The flourishing of Peer-to-Peer (P2P) applications has encouraged extensive research on end-to-end anonymity. In particular, interactive services such as Voice over IP (VoIP) are becoming extremely popular and require low latency. Preserving the anonymity of users in such services is becoming a major challenge. While existing schemes provide anonymity for the communicating parties;they incur high latency and are not suitable for interactive services. Even designs that attempt to reduce the latency employ an encryption scheme that involves a comparatively high computation overhead and delay. In this paper, we describe a novel low-latency P2P scheme that provides anonymity for both sender and receiver while adhering to strict and low bounds of delay, communication and bandwidth overheads. The design offers resistance against various attacks including a coalition of malicious peers. It has inherited scalability and fault tolerance and is applicable for various interactive P2P services, such as instant messaging, VoIP and video conference.
