Intrusion-Tolerant Jini Service Architecture for Ensuring Survivability of U-Services Based on WSN
U-Service environment based on WSN(Wireless Sensor Network) is poor in reliability of connection and has a high probability that the intrusion and the system failure may occur. Therefore, it is very important to ensure that the legitimate users make use of trustable services without discontinuance or obstacle of the services they are enjoying despite the presence of failures and intrusions. In this paper, we propose an intrusion-tolerant Jini service architecture integrating security and survivability mechanisms in order to provide end users with Jini services having a persistent state in wireless sensor networks. The proposed architecture is able to protect a Jini system 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 test-bed, 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.
