Abstract
An order-preserving encryption (OPE) encryption method receives a plaintext (clear text) and generates a ciphertext (encrypted text) using a software arbitrary precision floating point libraries during initial recursive computation rounds. In response to the ciphertext space reducing to breakpoint, the OPE encryption method continues computations using a hardware floating point processor to accelerate the computation. In this manner, the OPE encryption method enables efficient order preserving encryption to enable range queries on encrypted data.
