In recent years, USN technology has become one of the major issues in business and academia. This paper analyzes USN services from a security point of view and proposes a security model of USN middleware that plays a bridge role in linking heterogeneous sensor network to USN applications. In USN environment, sensor networks transmit data sensed from all distributed sensor nodes to USN middleware. And then USN middleware processes the received sensing data, makes information for supporting specific application service, and transmits the information to appropriate USN application. Like this, USN middleware plays a significant role in USN service. If the USN middleware is compromised, USN service might be not functioning normally. Hence, security in USN middleware is very important. In this paper, we propose security functions in USN middleware and specify a USN middleware security model that the security functions are reflected in.
