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. WebMay 1, 2024 · Firstly, we construct an order preserving encryption network by extracting and pre-processing each dimension of data. Based on the order preserving encryption network, we proposed an MDOPE scheme that provides fine-grained query services to users by supporting the multi-dimensional data range query. greer lucas
