Abstract

Service-based Systems (SBS) have the advantage of composing distributed systems from various services provided by multiple providers transparently. In addition to functional correctness, multiple non-functional QoS requirements should also be satisfied in such systems. Among these QoS requirements, security protection and real-time performance are the two major concerns. However, neither application users, nor service providers, have adequate control over such QoS of SBS. In this paper, an approach to the design of SBS with the capability of tradeoff between security and service delay of composite services running across various service hosts is presented in order to satisfy both security and real-time performance requirements simultaneously.
