Securing context-aware applications using environment roles
Michael J. Covington,Wende Long,Srividhya Srinivasan,Anind K. Dev,Mustaque Ahamad,Gregory D. Abowd +5 more
TL;DR: By introducing environment roles, this work creates a uniform access control framework that can be used to secure context-aware applications and presents a security architecture that supports security policies that make use of environment roles to control access to resources.
Journal ArticleDOI
Causal memory: definitions, implementation, and programming
TL;DR: This paper provides a formal definition of causal memory and gives an implementation for message-passing systems, and describes a practical class of programs that, if developed for a strongly consistent memory, run correctly with causal memory.
Journal ArticleDOI
The grid protocol: a high performance scheme for maintaining replicated data
TL;DR: In the new protocol, transaction processing is shared effectively among nodes storing copies of the data, and both the response time experienced by transactions and the system throughput are improved significantly.
Proceedings ArticleDOI
Incentives in BitTorrent induce free riding
Seung Jun,Mustaque Ahamad +1 more
TL;DR: The analysis and the experimental results show that the original incentive mechanism of BitTorrent can induce free riding because it is not effective in rewarding and punishing downloaders properly, and a new mechanism proposed is shown to be more robust against free riders.
Proceedings ArticleDOI
A context-aware security architecture for emerging applications
TL;DR: This document provides a concrete realization of a generalized access control model that makes significant use of contextual information in policy definition by presenting a system-level service architecture, as well as early implementation experience with the framework.
