Comment on the Security of an Order-Preserving Encryption Scheme Using Pseudo-Random Function
Minkyu Kim, Je Hong Park, Dongyoung Roh · IEICE Transactions on Communications · 2016
Since the first formal cryptographic study of order-preserving encryption (OPE) by Boldyreva et al., few OPE schemes with provable security have been published. In this paper, we analyze the security of Jho et al.'s OPE scheme, and show that it is not POPF-CCA secure in opposition to what they claim.
