An Authorization Framework for Database Systems

Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...

A linear programming framework for logics of uncertainty

Several logics for reasoning under uncertainty distribute probabil ity mass over sets in some sense These include probabilistic logic Dempster Shafer theory other logics based on belief functions and second order probabilistic logic We show that these logics are in stances of a certain type of linear programming model typically with exponentially many variables We also show how a single linear ...

Architectural Framework for Web Services Authorization

This paper proposes an authorization architecture for Web services. It describes the architectural framework, the administration and runtime aspects of our architecture and its components for secure authorization of Web services as well as the support for the management of authorization information. The paper also describes authorization algorithms required to authorize a Web service client. Th...

Authorization Framework for Service Oriented Architecure

Setting up secure application architecture is very challenging. The Service Oriented Architecture design allows and requires centrally manageable security services, among them the authorization service is the key to build model based security infrastructure. Although the theory of different security models are well-known, the definition and coding of the authorization rules are not complicated,...
