WebApr 26, 2009 · Order-preserving encryption (OPE) was first proposed by Agrawal et al. [32] in 2004, but they did not provide formal security proof. In 2009, Boldyreva et al. [33] put forward an... WebOct 24, 2016 · In this work, we consider a related primitive called order-revealing encryption (ORE), which is a generalization of OPE that allows for stronger security. We begin by constructing a new ORE scheme for small message spaces which achieves the "best-possible" notion of security for ORE.
