An Approach for Mobile Agent Security and Fault Tolerance using Distributed Transactions
Authors: Hartmut Vogler, Thomas Kunkelmann, Marie-Louise Moschgath
Venue: Proceedings of the 1997 International Conference on Parallel and Distributed Systems (1997)

Mobile agents are no longer a theoretical issue since different architectures for their realization have been proposed. With the increasing market of electronic commerce it becomes an interesting aspect to use autonomous mobile agents for electronic business transactions. Being involved in money transactions, supplementary security features for mobile agent systems have to be ensured. In this paper we present an architecture for a mobile agent system which guarantees security for the host as well as security for the agent. This architecture additionally offers fault tolerance for the whole agent system at a high level. To handle these issues for mobile agents we use various encryption mechanisms and we apply a novel method for mobile agent systems by using distributed transactions processing based on the OMG Object Transaction Service in our architecture. With this security architecture an agent will be enabled to do money transactions.
Development of a Software Security Assessment Instrument to Reduce Software Security Risk
Authors: David P. Gilliam, John C. Kelly, John D. Powell, Matt Bishop
Venue: Proceedings of the 10th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2001)

This paper discusses joint work by the California Institute of Technology's Jet Propulsion Laboratory and the University of California at Davis (UC Davis) sponsored by the National Aeronautics and Space Administration to develop a security assessment instrument for the software development and maintenance life cycle. The assessment instrument is a collection of tools and procedures to support development of secure software. Specifically, the instrument offers a formal approach for engineering network security into software systems and application throughout the software development and maintenance life cycle. The security assessment instrument includes a Vulnerability Matrix (VMatrix) with platform/ application, and signature fields in a database. The information in the VMatrix has become the bases for the Database of Vulnerabilities, Exploits, and Signatures (DOVES) at UC Davis. The instrument also includes a set of Security Assessment Tools (SAT), including the development of a property-based testing tool by UC Davis, to slice software code looking for specific vulnerability properties. A third component of the research is an investigation into the verification of software designs for compliance to security properties. This is based on innovative model checking approaches that will facilitate the development and verification of software security models
A Scalable Architecture for Differentiated Services
Authors: C. L. Lee, J. R. Chen, Y. C. Chen
Venue: Proceedings of the 22nd International Conference on Distributed Computing Systems (2002)

Differentiated services (DiffServ) model is a potential solution for providing quality of services (QoS) on the Internet. In this paper, we propose a scalable architecture that fulfills the design philosophy of the DiffServ model. Different from other existing architectures, our proposed architecture puts complexity on edge routers so that core routers do not need to support any specific function for service differentiation. Further, the proposed architecture only needs few additional functions in edge routers. Thus its deployment is simpler than most existing architectures. We also address how to achieve weighted proportional fairness solely by edge routers.
A Tool for Secure Inter-Organizational Computing
Authors: Myong H. Kang, Judith N. Froscher
Venue: Proceedings of the 10th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2001)

As the globalization of business becomes common practice, e-business and enterprise application integration receive much attention. In the case of enterprise application integration across organizations, participating organizations want to maintain autonomy and need mutual protection during the cooperation among organizations. These seemingly conflicting requirements have to be satisfied in an enterprise application integration environment. In this paper, we describe a solution for these apparent contradictory requirements and introduce a tool for secure inter-organizational computing.
Coordinating Open-Source Software Development
Authors: Davor Cubranic, Kellogg S. Booth
Venue: Proceedings of the 8th Workshop on Enabling Technologies on Infrastructure for Collaborative Enterprises (1999)

Open-source software projects are arguably the quintessential example of distributed software development, with their openness to a large pool of world-wide contributors and loose organizational structure. To cope with the demands this openness and fluidity place on the development process, open-source projects have evolved their own methods and organization. This paper looks at the ways some of the major and most successful open-source projects deal with the issue of coordination among their many contributors. Although each of the projects examined here developed some unique practices, there are also significant commonalities. The paper then goes on to indicate some of the problems caused by the existing practices, and put forward some possible approaches to OSS coordination that could make open-source software development more efficient.
Textual Information Dissemination in Distributed Event-Based Systems
Authors: Manolis Koubarakis
Venue: Proceedings of the 22nd International Conference on Distributed Computing Systems (2002)

We define formally the data models WP and AWP especially designed for the dissemination of textual information in distributed event-based systems. We also define the problems of satisfiability, satisfaction, filtering and entailment, and point out that these problems are fundamental for the deployment of models like the ones presented here in distributed event-based systems.
On Communication Security in Wireless Ad-Hoc Sensor Networks
Authors: Sasha Slijepcevic, Miodrag Potkonjak, Vlasios Tsiatsis, Scott Zimbeck, Mani B. Srivastava
Venue: Proceedings of the 11th IEEE International Workshops on Enabling Technologies: nfrastructure for Collaborative Enterprises (2002)

Networks of wireless microsensors for monitoring physical environments have emerged as an important new application area for wireless technology. Key attributes of these new types of networked systems are the severely constrained computational and energy resources, and anad hoc operational environment. This paper is a study of the communication security aspects of these networks. Resource limitations and specific architecture of sensor networks call for customized security mechanisms. Our approach is to classify the types of data existing in sensor networks, and identify possible communication security threats according to that classification. We propose a communication security scheme where for each type of data we define a corresponding security mechanism. By employing this multitiered security architecture where each mechanism has different resource requirements, we allow for efficient resource management, which is essential for wireless sensor networks.

Authors: Tsang Hin Chung, Leung Kwong Sak, Lee Kin Hong
Venue: Proceedings of the 10th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2001)

With the advance of smart card technology and the growing demand for secure applications in the community, many researches are being done on smart-card based systems from in-house applications to Internet-based applications. In this paper, we propose a comprehensive smart-card based authentication protocol and a secret key distribution scheme with failure handling. Compared with other similar protocols, our protocol can be embedded in the biometric-based local authentication system. Also, it can resist replaying attacks, perform mutual authentication, handle the smart card and the server failures properly without retaining the deficiency of those protocols.
Position Paper on Integrated Broadband Environment for Personalized TV Experience (IBEX)
Authors: Yoshihisa Gonno, Fumihiko Nishio, Yasuaki Yamagishi, Tomohiro Tsunoda
Venue: Proceedings of the 9th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2000)

Digital broadcasting systems have been coming into wide use all over the world. Efficient use of bandwidth allows us to transport hundreds of TV programs through a single broadcasting satellite to millions of user terminals simultaneously. On the other hand, millions of multimedia contents, including TV-like streaming live programs, are just going to be distributed over the Web. In order to make the most use of the digital information infrastructure, various forms of information must be well-structured in common ways between TV and the Web environment from every point of view such as authoring, delivery, browsing, searching and retrieval. Well-structured information will make it possible for us to be well navigated in floods of services between TV and the Web seamlessly. In these senses, we have reported basic ideas on a future framework for integration of TV and the Web [1][2][3][4].As a next step towards the integration of TV and the Web environment, we started a new project on integrated broadband environment for personalized TV experience (IBEX). This is a position paper on IBEX describing an architectural overview of future multimedia environment. The IBEX project also intends to provide a service model for the TV-Anytime [5] framework. The concept of the IBEX features three major viewpoints towards the future TV experience. To release audience from time constraint scheduled by broadcasters is the first target. Then to get seamless and adaptive access between TV and the Web environment from anywhere in the world is also important. In addition, such TV experience is to be securely personalized for individual audience. In order to achieve open framework, these viewpoints must be properly developed in conjunction with well-organized data models and system architecture based on de facto standard technology. The IBEX will provide a prototype system model built on upcoming integrated broadband digital TV infrastructure.
Attribute Partitioning Algorithm in DOODB
Authors: Soonmi Lee, Hae Chull Lim
Venue: Proceedings of the 1997 International Conference on Parallel and Distributed Systems (1997)

In distributed object-oriented databases (DOODB), objects is distributed in different sites on communication networks. In DOODB, class fragmentation to divide a class into fragments is needed for improving performance and for reducing data transfer. Class fragmentation is different from conventional relational databases. We have proposed the vertical class fragmentation to reflect the characteristics of object-oriented databases. In this paper, we define the attribute partitioning algorithm and describe the results of implementation and comparison.
WEBSIGN: A Looking Glass for e-Services
Authors: Cyril Brignone, Salil Pradhan, John Grundbäck, Alan McReynolds, Mark T. Smith
Venue: Proceedings of the 10th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2001)

Desktop browsers are excellent for browsing web sites but they keep users tethered. Wireless browsing technologies such as WAP and i-mode untether nomadic users by making these services available on the move. However, it is not clear if users will be satisfied with free form browsing offered by these wireless technologies. We believe that in addition to free form web browsing, nomadic users will choose to interact with e-services in their environment, if the interaction is transparently setup. Based on this belief, we have created a PDA based system that essentially provides nomadic users with a digital looking glass for viewing and interacting with e-services associated with physical objects and places (fig 1). In this paper, we present an overview of this system--Websign.
Secure Workflow Environment

Venue: Proceedings of the 6th Workshop on Enabling Technologies on Infrastructure for Collaborative Enterprises (1997)

Abstract: Workflow management products are deployed increasingly in almost all business activities and domains. Heterogeneity and geographical distribution are key features of the workflow environment. Workflow environments, therefore, must bridge the geographical barrier in a seamless and secure fashion. In addition, this environment must be platform-independent. In this paper, we present a Web-based secure workflow environment. Our approach integrates public-key encryption with the World Wide Web. Our goal is to provide a Web-based workflow solution so that a group-oriented virtual private network can be established across different geographical locations on the public Internet in a secure manner. Security for workflow technology on the Internet needs to be addressed from the ground up, and must be an integral part of the workflow environment. To this end, a combination of the Secure Sockets Layer (SSL) and a public-key infrastructure may be used. Our solution relies on the portability of the Java language. Such a solution would support the "write once, run anywhere" paradigm that Java advocates. This paper describes the traditional workflow mechanisms and discusses state-of-the-art workflow environments. A discussion of the future direction for a secure workflow technology is also presented.
Action Port Model: A Mixed Paradigm Conceptual Workflow Modeling Language
Authors: S. Carlsen
Venue: Proceedings of the 3rd IFCIS International Conference on Cooperative Information Systems (1998)

Workflow technology is a particular kind of IT for supporting work by enacting explicitly modeled and represented business processes. Thus, conceptual models of business and work processes are essential for process design as well as for process support in the form of workflow enactment. We describe the APM (Action Port Model) workflow modeling language which builds upon existing IS conceptual modeling languages. Even if based on traditional languages, APM is intended to be the basis for a flexible workflow support environment supporting ad hoc workflow, conform to ideas of workflow models as plans for situated action.

TWSAPI: A Generic Teamwork Services Application Programming Interface
Authors: Engin Kirda, Gerald Reif, Harald Gall, Pascal Fenkam
Venue: Proceedings of the 22nd International Conference on Distributed Computing Systems (2002)

One of the problems faced by large, global organizations and enterprises is to effectively enable their employees to collaborate across locations. People need collaborative work support while they are on the move and have to share business documents and know-how. Although much work has been done in the area of Computer Supported Collaborative Work (CSCW) to date, supporting mobility is only recently receiving attention. Hence, most of the existing approaches do not deal with emerging mobile teamwork requirements such as locating business documents and expertise through distributed searches, advanced subscription and notification, community building, and mobile information sharing and access. Furthermore, existing applications and approaches are usually difficult to customize to business-specific processes and requirements. The MObile Teamwork Infrastructure for Organizations Networking (MOTION)1 system addresses these requirements and provides a generic teamwork services Application Programming Interface (API), TWSAPI, that can be used to build organization-specific collaborative applications. In this paper, we give an overview of the MOTION TWSAPI and illustrate its usage in building an application that provides document review support.
Stable Transaction Management for Preserving the Global Integrity Constraints in Multidatabase Systems
Authors: K. Lee, S. Park
Venue: Proceedings of the 3rd IFCIS International Conference on Cooperative Information Systems (1998)

The multidatabase systems(MDBSs) are an integration of local database systems into a global distributed database system. The objectives of global transaction management are to avoid the inconsistent retrievals and to guarantee the global serializability under the existence of indirect conflict which is unknown to the global transaction manager(GTM). Many researches have shown that it is difficult to design the global concurrency control method because of local autonomy.Hence, we adopt the characteristics of global integrity constraints so that inconsistent global schedule can be prohibited and the higher degree of concurrency can be achieved. In this paper, we propose the transaction model for maintaining the global integrity constraints and define the stable global transaction that cannot have any indirect conflict between global transactions. We also propose the optimistic concurrency control method to guarantee the global serializability and logical consistency.
Spatial Presentation and Aggregation of Georeferenced Data
Authors: Kengo Koiso, Takahiro Matsumoto, Katsumi Tanaka
Venue: Proceedings of the Sixth International Conference on Database Systems for Advanced Applications (1999)

In this paper, we will introduce a method of spatial presentation of georeferenced data in a three-dimensional space. Photographs, Quicktime VR's, videos, and computer graphic renderings provide realistic presentations rich in visual information. We believe, however, there is an issue of visualizing georeferenced data such as attribute data for spatial objects as well as showing the objects themselves.We will introduce orientation-based visualization model for visualizing georeferenced data, and we will discuss abstraction of the georeferenced data through their spatial aggregation in the space specified by a user.
Instruction Cache Prefetching with Extended BTB
Authors: Shyh-An Chi, R.-Ming Shiu, Jih-Ching Chiu, Si-En Chang, Chung-Ping Chung
Venue: Proceedings of the 1997 International Conference on Parallel and Distributed Systems (1997)

Instruction cache prefetching is a technique to reduce the penalty caused by instruction cache misses. The prefetching methods generally determines the target line to be prefetched based on the current fetched line address. However, as the cache line becomes wider, there may be multiple branches in a cache line which hurdles the decision made by these methods. This paper develops a new instruction cache prefetching method in which the prefetch is directed by the prediction on branches. We call it the branch instruction based (BIB) prefetching. In BIB prefetching, the prefetch information is recorded in an extended BTB. Simulation results show that, the BIB prefetching outperforms the traditional sequential prefetching by 7% and other prediction table based prefetching methods by 17% on average. As the BTB designs become more sophisticated and achieve higher hit and accuracy ratio, the BIB prefetching can achieve higher performance.
Distributed Workflow Management: The TEAM Model
Authors: Giacomo Piccinelli
Venue: Proceedings of the 3rd IFCIS International Conference on Cooperative Information Systems (1998)

In the last few years, workflow systems have been the base for business-process re-engineering (BPR) but the characteristics of processes are changing and new types of problems need to be addressed. Different organizations dynamically group together (federation) to support complex projects requiring different competencies and coordination is fundamental. Focusing on the interaction among distinct distributed PCEs (process-centered environments), an abstraction model is proposed for the federation based on the partitioned workspace metaphor coupled with a CSP-like process-definition language. A component-based architecture is presented for the actual enactment of the model. Both the development and the enactment environments are presented and the interaction with local PCEs is discussed.
Looking at the Whole Picture: A Case Study of Analyzing a Virtual Workplace
Authors: Michelle Potts Steves, Emile L. Morse
Venue: Proceedings of the 10th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises (2001)

In a previous study, we analyzed data from a field study to determine the usability problems in a groupware system. That 75% of the system use was asynchronous surprised us. Consequently, we suspected that the user-centered method that had been employed in that evaluation, might have been insufficient to detect problems related to such heavy asynchronous use. Re-analysis of the data using an artifact-centered approach revealed additional support for our initial findings and some new usability issues. In combination, we believe that user-centered and artifact-centered methods can yield superior usability analyses for systems that support both synchronous and asynchronous collaboration, and provide application developers with more appropriate priorities for addressing usability problems and system design.
Panel on Cooperative MultiAgent Systems for the Web
Authors: Anupam Joshi
Venue: Proceedings of the Second IFCIS International Conference on Cooperative Information Systems (1997)

There is an explosion in the amount of information that is accessible by the public, especially with the advent of the World Wide Web. With this information only expected to increase as time goes on, there is an obvious need for mechanisms which would allow individuals to access the right information. In the context of the Web, this can be referred to as personalization of the information source(s). The author touches upon various issues and technologies, as well as their interrelationships. These include interaction between agents, cooperation amongst heterogeneous information sources, and coordinating the activities of these agents using workflow.
