大规模在线监控设备的搜索与识别

In the cyber space, search and exploitation of large-scale online resources are giving the guarantee for ensure national security of critical infrastructure. Surveillance devices that have been the most important and pervasive physical devices, bridging between the physical world and the cyberspace, are widely used in various domains, including government agencies, transportation, plant (Water & Electric), schools and families. Surveillance device discovery, as the first barrier protection for the infrastructure, is becoming very important to national security and social development. There are several challenges and problems in search and recognition of large-scale surveillance devices in the cyber space. We propose a scheduling optimization algorithm for device discovery based on active scanning and passive listening to improve the effectiveness of the device search and reduce the time latency. We propose the algorithm of nonparametric Bayesian based on text-based techniques to discover the unknown surveillance devices in the cyber space. We propose a surveillance device fingerprint model based on deep learning algorithms to improve the accuracy of recognition of a wide variety of surveillance devices. We build a prototype system to verify the relevant technical equipment and search program. We expect to publish 6-8 papers on international conferences and important journals, propose more than 2-4 national patents, and make efforts to produce a certain influence in related research fields.
