Intrusion-Tolerant Jini Service Architecture for Integrating Security and Survivability Support in DSN

초록

Ubiquitous service environment based on DSN (distributed sensor networks) is poor in reliability of connection and has a high probability that the intrusion and the system failure may occur. In this paper, we propose an intrusion-tolerant Jini service architecture for integrating security and survivability support in order to provide end users with Jini services having a persistent state in ubiquitous environments. The proposed architecture is able to protect Jini service delivery not only from faults such as network partitioning or server crash but also from attacks exploiting flaws. It is designed to provide performance enough to show a low response latency so as to support seamless service usage. Through the experiment on a testbed, we have confirmed that the architecture is able to provide high security and availability at the level that the degradation of services quality is ignorable.
