Secure Range Query Processing over Untrustworthy Cloud Services

Theodoros Tzouramanis
2017 Proceedings of the 21st International Database Engineering & Applications Symposium on - IDEAS 2017  
Privacy is a major concern in cloud computing since clouds are considered as untrusted environments. In this study, we address the problem of privacy-preserving range query processing on clouds.  ...  In this case, a system often confronts a high rate of incoming data. Prior schemes may thus suffer from potential performance issues, e.g., overload or bottleneck.  ...  [15] present PINED-RQ for serving efficient range query processing in clouds via secure indexes. Nonetheless, the high rate of new data is not discussed in this work.  ...

A Review Based on Order Preserving Encryption-Scheme to Preserve the Order of Encrypted Cloud Data Search

2017 International Journal of Recent Trends in Engineering and Research  
The data on Cloud computing is encrypted due to security concern or the factor of third party to excavate into it. As the consequence to this, the search over encrypted data becomes a complex task.  ...  Even though with good security of one-to-many OPE the Cloud can get the information of the plain text if differential attacks occurred on the cipher text by calculating the differences between the cipher  ...  That is, a remote untrusted database server is able to index the (sensitive) data it receives, in encrypted form, in a data structure that permits efficient range queries i.e. asking the server to return  ...
