Enabling Efficient and Geometric Range Query With Access Control Over Encrypted Spatial Data.
IEEE Transactions on Information Forensics and Security(2019)
摘要
As a basic query function, range query has been exploited in many scenarios such as SQL retrieves, location-based services, and computational geometry. Meanwhile, with explosive growth of data volume, users are increasingly inclining to store data on the cloud for saving local storage and computational cost. However, a long-standing problem is that the user's data may be completely revealed to the...
