Security analysis for order preserving encryption schemes
Liangliang Xiao, I‐Ling Yen · 2012
The development of third-party hosting, IT out-sourcing, service clouds, etc. raises important security concerns. It is safer to encrypt critical data that is hosted by a third party. However, a database must be able to process queries on the encrypted data. Many algorithms have been developed to support search query processing on encrypted data, including order preserving encryption (OPE) schemes.
