Ope order preserving encryption
WebJan 11, 2024 · The order-preserving encryption (OPE) problem was initially formulated by the database community in 2004 soon after the paradigm database-as-a-service (DaaS) was coined in 2002. Over the past two decades, OPE has drawn tremendous research interest from communities of databases, cryptography, and security; we have witnessed … WebDeterministic and Order-preserving Encryption (OPE) Deterministic and Order-preserving Encryptions are sorts of partial encryptions that allow some types of operations (not all). These methods of encryption have been employed in academia in CryptDB and more recently in production in systems such as Numer.ai.
