Abstract
Although spatial database applications and location based systems require the execution of several types of searching operations over spatial data, works related to encrypted spatial data address a limited set of searching operations, restricting their use in real applications. This article proposes an encryption scheme that enables circular range search, rectangular range search and kNN operation over encrypted spatial data. Also, we have compared the encryption functions of our scheme with other encryption schemes and, even though the results have shown a similar performance, our work allows the execution of circular and rectangular range searches by using a unique encryption scheme.
