Assurance Services For Business-To- Business Electronic Commerce: A Framework And Implications, Deepak Khazanchi, Steve G. Sutton Jan 2000

Assurance Services For Business-To- Business Electronic Commerce: A Framework And Implications, Deepak Khazanchi, Steve G. Sutton

Information Systems and Quantitative Analysis Faculty Publications

The electronic commerce assurance market has been estimated to be potentially worth $11 billion. To date the focus of assurance services has largely been on web commerce (and therefore business to consumer) related services, leaving the business-to-business (B2B or B-to-B) electronic commerce market relatively untapped. Yet, with Electronic Data Interchange (EDI) being mandated by large companies and government agencies, small- to medium-sized firms have struggled to acquire and implement this technology with little understanding of this new age of electronic commerce. As the ubiquitous Internet allows more firms to become EDI-capable, there is an imminent need for having some independent …

A Pairwise Key Pre-Distribution Scheme For Wireless Sensor Networks, Wenliang Kevin Du, Jing Deng, Yunghsiang S. Han, Pramod K. Varshney

Electrical Engineering and Computer Science - All Scholarship

This paper, we provide a framework in which to study the security of key pre-distribution schemes, propose a new key pre-distribution scheme which substantially improves the resilience of the network compared to previous schemes, and give an in-depth analysis of our scheme in terms of network resilience and associated overhead. Our scheme exhibits a nice threshold property: when the number of compromised nodes is less than the threshold, the probability that communications between any additional nodes are compromised is close to zero. This desirable property lowers the initial payoff of smaller-scale network breaches to an adversary, and makes it necessary …

Disec: A Distributed Framework For Scalable Secure Many-To-Many Communication, Lakshminath R. Dondeti, Sarit Mukherjee, Ashok Samal Jan 2000

Disec: A Distributed Framework For Scalable Secure Many-To-Many Communication, Lakshminath R. Dondeti, Sarit Mukherjee, Ashok Samal

School of Computing: Conference and Workshop Papers

Secure one-to-many multicasting has been a popular research area in the recent past. Secure many-to-many multicasting is becoming popular with applications such as private conferencing and distributed interactive simulation. Most of the existing secure multicasting protocols use a centralized group manager to enforce access control and for key distribution. In the presence of multiple senders it is desirable to delegate group management responsibility to all the senders. We propose a distributed group key management scheme to support secure many-to-many communication. We divide key distribution overhead evenly among the senders. Our protocol is scalable and places equal trust in all the …

Almi: An Application Level Multicast Infrastructure, Dimitrios Pendarakis, Sherlia Shi, Dinesh Verma, Marcel Waldvogel Jan 2000

Almi: An Application Level Multicast Infrastructure, Dimitrios Pendarakis, Sherlia Shi, Dinesh Verma, Marcel Waldvogel

All Computer Science and Engineering Research

The IP multicast model allows scalable and efficient multi-party communication, particularly for groups of large size. However, deployment of IP multicast requires substantial infrastructure modifications and is hampered by a host of unresolved open problems such as reliability, flow and congestion control, security and access control. Motivated by these problems, we have designed and implemented ALMI, an application level group communication middleware, which does not rely on network infrastructure support and thus, allows accelerated deployment and simplified configuration at the cost of a relatively small increase in traffic load. ALMI is tailored toward support of multicast groups of relatively small …

On Maintaining Group Membership Data In Ad Hoc Networks, Gruia-Catalin Roman, Qingfeng Huang, Ali Hazemi Jan 2000

On Maintaining Group Membership Data In Ad Hoc Networks, Gruia-Catalin Roman, Qingfeng Huang, Ali Hazemi

All Computer Science and Engineering Research

The design of ad hoc mobile applications often requires the availability of a consistent view of the application state among the participating hosts. Essential to constructing a consistent view is the ability to know what hosts are within proximity of each other, i.e., form a group in support of the particular application. In this paper we propose an algorithm that allows hosts within communication range to maintain a consistent view of the group membership despite movement and frequent disconnections. The novel features of this algorithm are its reliance on location information and a conservative notion of logical connectivity that creates …

A Model For Transforming Legacy Systems In A Client/Server Environment Based On The Unified Modeling Language(Uml), Leon Stevens

CCAC Theses and Dissertations

In this dissertation the researcher developed the methodology for the migration of computer programs from a legacy architecture to client/server architecture. System migrations have failed frequently, and even so-called successful migrations may have serious usability problems. Additional difficulties include missing documentation of the existing program(s), the persons who developed the existing system are not available for consultation, and, frequently, there are important operational and economic issues that must be considered. The client/server environment is quite different from the source environment; the operating system and implementation languages have changed, and system requirements may have been greatly expanded, frequently including the Internet. …

Decentralised H_{\Infty} Load Frequency Controller Design Based On Ssvs, Hasan Çi̇men Jan 2000

Decentralised H_{\Infty} Load Frequency Controller Design Based On Ssvs, Hasan Çi̇men

Turkish Journal of Electrical Engineering and Computer Sciences

The decentralised load-frequency controller design problem concerned is translated into an equivalent problem of decentralised controller design for a multi-area multi-input multi-output (MIMO) control system. It is shown that subject to a condition based on the structured singular values (SSVs), each local area load-frequency controller can be designed independently. The stability condition for the overall system can be stated as to achieve a sufficient interaction margin. It is demonstrated by computer simulation that within this general framework, local H$_{\infty}$ controllers can be designed to achieve satisfactory performances for a sample two-area power system.

Quality Of Service Management For Non-Guaranteed Networks, Tarek Madkour Jan 2000

Quality Of Service Management For Non-Guaranteed Networks, Tarek Madkour

Archived Theses and Dissertations

The increasing dominance of multimedia communication posed new requirements for the underlying systems. Multimedia data, formally called continuous media, has time constraints that impose real time limitations for their transmission. Certain levels of service, called Quality of Service (QoS), need to be considered when handling continuous media. The present work utilizes QoS concepts for networks that do not have inherent QoS support. The thesis aims at verifying the possibility of having QoS-controlled communication on non-guaranteed networks. A basic QoS architecture is designed where already existing QoS concepts are adapted to work with non-guaranteed networks. The architecture provides the facilities of …

Imprecise Answers In Distributed Environments: Estimation Of Information Loss For Multi-Ontology Based Query Processing, Eduardo Mena, Vipul Kashyap, Arantza Illarramendi, Amit P. Sheth

Kno.e.sis Publications

The World Wide Web is fast becoming a ubiquitous computing environment. Prevalent keyword-based search techniques are scalable, but are incapable of accessing information based on concepts. We investigate the use of concepts from multiple, real-world pre-existing, domain ontologies to describe the underlying data content and support information access at a higher level of abstraction. It is not practical to have a single domain ontology to describe the vast amounts of data on the Web. In fact, we expect multiple ontologies to be used as different world views and present an approach to "browse" ontologies as a paradigm for information access. …
