Key-Controlled Order-Preserving Encryption

HU Mengke; GAO Juntao

Abstract: In this paper we study order-preserving encryption (OPE), a primitive in the database community for allowing efficient range queries on ecrypted data. OPE was suggested by Agrawal et al [1], and was throughly studied by Boldyreva et al [2]. In this paper we present a practical OPE scheme, which is a key-controlled algorithm, based on simple computation. A primary analysis shows that our algorithm is secure enough
