On Security of the Utility Preserving RASP Encryption

Many potential users hesitate to use cloud computing because of the data confidentiality issue. Can the people compute on untrusted public cloud platform with both data confidentiality and data utility preserved? Recent study has revealed that a convexity preserving encryption RASP can be used to construct confidentiality preserving and efficient range query service, which is one of the most frequently used query types for online data analytics. Convexity preserving encryption schemes, such as the RASP encryption, preserve the topology of the queried range in the encrypted space.
