Practical forward secure group signature schemes
Authors: Dawn Xiaodong Song
Venue: Proceedings of the 8th ACM conference on Computer and Communications Security (2001)

A group signature scheme allows a group member to sign messages anonymously on behalf of the group, while in case of a dispute, a designated entity can reveal the identity of a signature's originator. Group signature schemes can be used as a basic building block for many security applications such as electronic banking systems and electronic voting. Two important issues -- forward security and efficient revocation -- have not been addressed by prior schemes. We construct the first forward-secure group signature schemes. While satisfying all the security properties proposed in previous group signature schemes, our schemes provide a new desired security property, forward-security: while the group public key stays fixed, a group signing key of a group member evolves over time such that compromise of a group signing key of the current time period does not enable an attacker to forge group signatures pertaining to the past time periods. Such forward-security is important to mitigate the damage caused by key exposure and particularly desirable for group signature schemes because the risk of signing key exposure escalates as the size of the group increases. Our schemes are provably secure in the random oracle model and under the strong RSA and decisional Diffie Hellman assumptions.Furthermore, we extend our forward-secure group signature scheme to provide a solution for the problem of group member exclusion without the need to re-key all other group members. When a group member is excluded, he should not be able to generate valid signatures any more and yet his previous signatures remain anonymous. We provide the first solutions which support both retroactive public revocation and backward unlinkability and the signature size is independent of the number of revoked members.

Using simulation to evaluate cargo ship design on the LPD17 program
Authors: Joseph C. Hugan
Venue: Proceedings of the 32nd conference on Winter simulation (2000)

As part of the design of the next generation Naval Amphibious Transport Dock Ship (LPD17), simulation was used to evaluate the arrangement and flow of cargo on the ship and to integrate material flow concepts with the overall design requirements (see Figure 1). The simulation model evaluated specific cargo load out scenarios to determine if the proposed material handling systems would satisfy specific mission criteria. The simulation was developed in 3D using a common database of CAD geometry to not only evaluate the throughput and utilization of proposed systems but also to verify that those systems could operate within the confined spaces of cargo ships. The model considered factors such as cargo type and arrangement, forklift speed, turning radius, elevator size, and elevator speed. The placement of cargo was driven from external files and a rule set was developed to allow for the automatic generation of an unload sequence. This paper will focus on the construction of the model, its data file flexibility, and the results of the missions evaluated during the project. It will also discuss the role 3D simulation played in validating this model and communicating specific simulation results.

CSCW Requirements and Evaluation
Authors: Peter J. Thomas
Venue:  (1995)

:Research in Computer Supported Cooperative Work (CSCW) has been progressing in academia for some time, feeding directly into the development of commercially-available groupware systems. At first limited to email and shared databases running on local area networks, recent advances in groupware technology have led to the development of sophisticated applications aimed specifically at the commercial user, ranging from workflow management systems to video conferencing. Now, as the availability of affordable systems is growing, so is the need for users and organisations to determine their requirements for future systems, and to evaluate how well available systems meet their needs. CSCW Requirements and Evaluation covers these and other important issues, providing both practical and academic perspectives on requirements and evaluation. It describes a variety of methods and approaches, based on specific case studies, and includes contributions from leading authorities in the field. Overall this volume provides invaluable reading for researchers and practitioners involved in CSCW, groupware development, information systems design, user-interface design, and organisational research.

Skepticism and floating conclusions
Authors: John F. Horty
Venue: Artificial Intelligence (2002)

The purpose of this paper is to question some commonly accepted patterns of reasoning involving nonmonotonic logics that generate multiple extensions. In particular, I argue that the phenomenon of floating conclusions indicates a problem with the view that the skeptical consequences of such theories should be identified with the statements that are supported by each of their various extensions.
Probabilistic congestion control for non-adaptable flows
Authors: Jörg Widmer, Martin Mauve, Jan Peter Damm
Venue: Proceedings of the 12th international workshop on Network and operating systems support for digital audio and video (2002)

In this paper we present a TCP-friendly congestion control scheme for non-adaptable flows. The main characteristic of these flows is that their data rate is determined by an application and cannot be adapted to the current congestion situation of the network. Typical examples of non-adaptable flows are those produced by networked computer games or live audio and video transmissions where adaptation of the quality is not possible (e.g., since it is already at the lowest possible quality level). We propose to perform congestion control for non-adaptable flows by suspending them at appropriate times so that the aggregation of multiple non-adaptable flows behaves in a TCP-friendly manner. The decision whether or not a flow is to be suspended is based on random experiments. In order to allocate probabilities for these experiments, the data rate of the non-adaptable flow is compared to the rate that a TCP flow would achieve under the same conditions. We present a detailed discussion of the proposed scheme and evaluate it through extensive simulation with the network simulator ns-2.

Using clustering techniques to detect usage patterns in a Web-based information system
Venue: Journal of the American Society for Information Science and Technology (2001)

Different users of a Web-based information system will have different goals and different ways of performing their work. This article explores the possibility that we can automatically detect usage patterns without demographic information about the individuals. First, a set of 47 variables was defined that can be used to characterize a user session. The values of these variables were computed for approximately 257,000 sessions. Second, principal component analysis was employed to reduce the dimensions of the original data set. Third, a two-stage, hybrid clustering method was proposed to categorize sessions into groups. Finally, an external criteria-based test of cluster validity was performed to verify the validity of the resulting usage groups (clusters). The proposed methodology was demonstrated and tested for validity using two independent samples of user sessions drawn from the transaction logs of the University of California's MELVYL on-line library catalog system (www.melvyl.ucop.edu). The results indicate that there were six distinct categories of use in the MELVYL system: knowledgeable and sophisticated use, unsophisticated use, highly interactive use with good search performance, known-item searching, help-intensive searching, and relatively unsuccessful use. Their characteristics were interpreted and compared qualitatively. The analysis shows that each group had distinct patterns of use of the system, which justifies the methodology employed in this study.

Visualization of particle traces in virtual environments
Authors: Falko Kuester, Ralph Bruckschen, Bernd Hamann, Kenneth I. Joy
Venue: Proceedings of the ACM symposium on Virtual reality software and technology (2001)

Real-time visualization of particle traces in virtual environments can aid in the exploration and analysis of complex three dimensional vector fields. This paper introduces a scalable method suitable for the interactive visualization of large time-varying vector fields on commodity hardware. A real-time data streaming and visualization approach and its out-of-core scheme for the pre-processing and rendering of data are described. The presented approach yields low-latency application start-up times and small memory footprints. A proof of concept systems was implemented on a low-cost Linux workstation equipped with spatial tracking hardware, data gloves and shutter glasses. The system was used to implement a virtual wind tunnel in which a volumetric particle injector can introduce up to 60000 particles into the flow field while an interactive rendering performance of 60 frames per second is maintained.
