Order-Preserving Encryption Secure Beyond One-Wayness
Semantic-security of individual plaintext bits given the corresponding ciphertext is a fundamental notion in modern cryptography. We initiate the study of this basic problem for Order-Preserving Encryption (OPE), asking “what plaintext information can be semantically hidden by OPE encryptions?” OPE has gained much attention in recent years due to its usefulness for secure databases, and has rec...
متن کاملA Note for the Ideal Order-Preserving Encryption Object and Generalized Order-Preserving Encryption
Order-preserving encryption (OPE) preserves the order of data in their ciphertexts and, hence, allows range search on the encrypted data without needing to decrypt them. Security analysis of OPE schemes is very important because OPE is not a perfect encryption algorithm (the ciphertexts leak the ordering information of the plaintexts). Most of the existing security analysis for the OPE schemes ...
متن کاملOrder-Preserving Symmetric Encryption
We initiate the cryptographic study of order-preserving symmetric encryption (OPE), a primitive suggested in the database community by Agrawal et al. (SIGMOD ’04) for allowing efficient range queries on encrypted data. Interestingly, we first show that a straightforward relaxation of standard security notions for encryption such as indistinguishability against chosen-plaintext attack (IND-CPA) ...
متن کاملSemi-order preserving encryption
Order preserving encryption (OPE) is a kind of encryption designed to support searches on ciphertexts. OPE encrypts plaintexts to ciphertexts with the same order, making it possible to efficiently compare ciphertexts without decryption. Because of its efficiency, OPE has been used in systems aimed at practical use. However, even though many OPE schemes have been proposed, all suffer from securi...
متن کاملStructure Preserving CCA Secure Encryption and Applications
In this paper we present the first CCA-secure public key encryption scheme that is structure preserving, i.e., our encryption scheme uses only algebraic operations. In particular, it does not use hashfunctions or interpret group elements as bit-strings. This makes our scheme a perfect building block for cryptographic protocols where parties for instance want to prove properties about ciphertext...
