We investigate client-server interaction where duties and rights of the parties are asymmetric, in the sense that the client is allowed to abort any session before the server has completed, but not vice versa. This implies that the client can interact with any server offering at least what she is looking for, but possibly more. We formalize such asymmetry in the setting of session types via a f...

In today’s world, many statistical questions require the use of computationalassistance. Our approach, presented in this thesis, combines the possibilities of the powerful statistical software environment XploRe, with the advantagesof distributed client/server applications, and the opportunities offered by theInternet. In order to offer the client access to a large community, the Ja...

The Clarens web services platform, described in a companion article, [15] acts as a go-between for distributed clients on the wide area network to access services using the widely XML-RPC and SOAP data serialization standards on top of the lower-level HTTP protocol. Its usefulness must ultimately be measured by the usefulness of the services and clients themselves. This paper is divided into tw...

One feature of Dynamic Host Configuration Protocol (DHCP) servers is the ability to assign static (fixed) IP Addresses for well-known clients in the Local Area Network (LAN) based on their Medium Access Control (MAC) addresses. This typically involves manual intervention by the network administrator to enter the correct MAC address and IP address information into the DHCP server configuration f...

Recently, both academia and industry have initiated research projects directed on integration of P2PSIP paradigm into communication systems. In this paradigm, P2P network stores most of the network information among participating peers without help of the central servers. The concept of self-configuration, self-establishment greatly improves the robustness of the network system compared with th...

Private query brings new challenges to the design of Database Management System (DBMS). A recent work of Blind Seer system introduces a new setup which has an efficient sublinear search for arbitrary boolean query. It splits an index server from server such that client can communicate with index server to retrieve encrypted records. During the query, the server learns nothing about the query. T...

The aim of this graduate project was to develop a prototype of a C# Managed DirectX Client Server Library for Shared Environments and to explore and learn networking in the C#.Net environments. A demo Teapot program has been implemented as a prototype which is implemented in C# and DirectX. This prototype contains five components namely a Server GUI, a Server library, a Client GUI, a Client Lib...

When outsourcing data to an untrusted database server, the data should be encrypted. When using thin clients or low-bandwidth networks it is best to perform most of the work at the server. In this paper we present a method, inspired by secure multi-party computation, to search efficiently in encrypted data. XML elements are translated to polynomials. A polynomial is split into two parts: a rand...
