Toward Securing Sensor Clouds
The authors aim to secure smart sensor networks, where computationally powerful sensing devices such as smartphones or cognitive radios interact with the cloud. In previous work, they have proposed a large-scale brokering framework, and they are researching several facets of securing sensors in the context of this framework. In this paper they discuss initial results for three portions of this effort, challenges that remain for secure sensor networks, and specific directions they are currently pursuing. In particular, they discuss the work on Sensor risk assessment, relating to the possession and environment of the smartphone sensors, New malware threats and defenses installed on the sensor network proper, and Defense against the side-channel analysis on the Software-as-a-Service infrastructure.
