Message Passing For Distributed QoS-Security Tradeoffs

Abstract

Information Assurance (IA) is of growing concern to the field of distributed systems. However, IA cannot be considered in isolation, as it interacts with Quality of Service (QoS); in the presence of limited resources, the security mechanisms employed for IA (e.g., firewalls, antivirus, encryption) usually adversely affect QoS levels delivered by a system. The system therefore needs to make a tradeoff between IA and QoS. This tradeoff is complicated by the fact that users' relative preferences over QoS/IA aspects change based on the situation, the interests of different users conflict, and tradeoff decisions made at one node in the distributed system typically affect other nodes as well.
