What Are Possible Security Threats in Ubiquitous Sensor Network Environment?

摘要

USN infrastructure means the logical and physical space which consists of all kinds of networks, which provides useful sensing information surrounding human being. It includes wireless sensor network, RFID, Mobile RFID, IP-USN, and wired sensor network. These kinds of network are sensing information providers for human beings and use different technologies to collect information from the environment and provide those information to information consumers. USN middleware provides USN infrastructure abstraction, complicated and integrated sensing information processing, Open Application Interface to the information consumer. The importance of USN middleware security lies in this role of USN middleware. It manages sensor networks and collects sensor data on the behalf of the sensing information consumer. Therefore a malicious consumer can disrupt the sensor networks through USN middleware and collect sensitive sensing information through USN middleware. Or, malicious sensor networks may provide contaminated sensing values to consumers through USN middleware. In this case, all information provided to consumers may be contaminated and destroyed. In this paper, we analyze possible security threats in USN environments. Based on this analysis, possible counter-threat measures can be taken.
