Abstract
Information sharing and transmission is an essential part of SUs in CRNs. Collaborative spectrum sensing requires the sharing of sensing reports between SUs and the FC. In database-driven CRNs, the location information and channel availability information are required to be transmitted between the database and registered SUs. Location privacy preservation is a promising approach to incentivize SUs to participate in the CRNs. The general form of privacy preservation is to transform the original sensitive data including sensing reports and location query into some anonymous from that are still useful and have limited impacts on the performance. Location privacy in CRNs is highly related to location privacy studied in participatory sensing and privacy preserving data publishing. However, due to the distinct features of CRNs, privacy preservation in CRNs has its own unique challenges. For example, the performance degradation caused by inaccurate location data in participatory sensing is allowable, while in collaborative spectrum sensing, the performance degradation means interference to PUs which is a very serious issue and is not allowed. Besides, the data formats, network protocols, aggregation rules are quit different in CRNs and other scenarios.
