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. WebWe abbreviate an order-preserving encryption or encoding scheme (the latter may not be strictly an encryption scheme) by OPE . OPE is primarily used in databases for processing SQL queries over encrypted data [ 2, 13 , 19 , 21 , 23 , 26 , 27 , 33 , 38 ], although it has also been used in the Order-preserving scheme Guarantees Leakage besides order iowa courts polk county
