Kerberos is the widely deployed authentication protocol. This document gives you comparison between NTLM and Kerberos authentication. And it gives information on how Kerberos authentication plays a vital role in authentication and delegation scenarios, and the situations where Kerberos authentication should be used or may be required in solution designs. Scenarios include business intelligence ...

--In view of sensitive data management, an efficient cryptographic access control scheme is proposed. Based on attribute-based encryption, the proposed scheme not only inherits flexibility and fine-grained access control for users, but also realizes cryptographic management for servers. In additional, the scheme alleviates the administering burdens on the server, and handle dynamic access polic...

We present an efficient protocol for the privacy-preserving, distributed learning of decision-tree classifiers. Our protocol allows a user to construct a classifier on a database held by a remote server without learning any additional information about the records held in the database. The server does not learn anything about the constructed classifier, not even the user’s choice of feature and...

In order to handle the database load for web scale applications, the conventional wisdom is that a cluster of database servers and a caching layer are essential. In this work, we argue that modern main memory database systems are often fast enough to consolidate this complex architecture into a single server (plus an additional fail over system). To demonstrate this claim, we design the Monoped...

This paper considers a multiserver queueing system with finite capacity. Customers that find the service facility being fully occupied are blocked and enter a virtual waiting room (called orbit). Blocked customers stay in the orbit for an exponentially distributed time and retry to occupy an idle server again. After completing a service, the server starts an additional job that we call an after...

In this paper, the development of a personal mobile Geographic Information System is described. The system is configured in a client-server architecture, involving mobile clients and a servicing server. With the use of Global Positioning System, the locations of a group of mobile clients are identified and these pieces of information are sent to server for additional services. For demonstration...

This paper describes a framework and a system for visualizing parallel Linda programs. The system is called VisuaLinda, which is a Linda server itself as well as a visualization tool. Since the visualization module is built-in the Linda server, programmers do not need to insert/delete additional sentences into/from their client programs in order to obtain visualization. This framework extremely...

To persistently maintain client-server connections in mobile ad-hoc networks, we investigate the reliable server pooling (RSP), where servers that can provide equivalent functionality are pooled together. The RSP is meant to increase the availability and survivability of the battlefield infrastructure by allowing clients to access a pool of redundant information sources. As a result, some faile...

The TreeDet (Tree Determinant) Server is the first release of a system designed to integrate results from methods that predict functional sites in protein families. These methods take into account the relation between sequence conservation and evolutionary importance. TreeDet fully analyses the space of protein sequences in either user-uploaded or automatically generated multiple sequence align...

The paper presents a distributed computing system that is based on evolutionary algorithms and utilizing a web browser on a client’s side. Evolutionary algorithm is coded in JavaScript language embedded in a web page sent to the client. The code is optimized with regards to the memory usage and communication efficiency between the server and the clients. The server side is also based on JavaScr...
