The goal: Not just better technology but better business processes that make a company more competitive. Client/server systems link clients and servers via a network to support distributed computation, analysis, and presentation, providing a common method for distributing computer power within companies. Although companies are embracing client/server technology when moving from legacy systems [...

Recently, major progress has been made towards the realisation of quantum internet to enable a broad range classically intractable applications. These applications such as delegated computation require running secure identification protocol between low-resource and high-resource party provide communication. In this work, we propose two protocols based on emerging hardware solutions, Physical Un...

The caching of data and/or locks at client workstations is an eeective technique for improving the performance of a client-server database system. This paper extends an earlier performance study of client-server caching in several ways. The rst is a re-examination of heuristics for deciding dynamically between propagating changes or invalidating remote copies of data pages in order to maintain ...

Human memory is not perfect – people constantly memorize new facts and forget old ones. One example is forgetting a password, a common problem raised at IT help desks. We present several protocols that allow a user to automatically recover a password from a server using partial knowledge of the password. These protocols can be easily adapted to the personal entropy setting [7], where a user can...
