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 the

Homomorphic encryption (HE) allows the execution of queries over encrypted data without requiring decryption. However, we found a lack of studies for investigating the use of HE in data warehouse (DW). In this article, we propose a framework that def

Several studies deal with mechanisms for processing transactional queries over encrypted data. However, little attention has been devoted to determine how a data warehouse (DW) hosted in a cloud should be encrypted to enable analytical queries proces
