2018/7/24
Order-revealing encryption (ORE) is a popular primitive for outsourcing encrypted databases, as it allows for efficiently performing range queries over encrypted data. Unfortunately, a series of works...
File-injection Attack and Forward Security for Order-revealing Encryption
Order-revealing Encryption Order-preserving Encryption File-injection Attack

The security of order-revealing encryption (ORE) has been unclear since its invention. Dataset characteristics for which ORE is especially insecure have been identified, such as small message spaces a...
Order-preserving encryption and its generalization order-revealing encryption (OPE/ORE) are used in a variety of settings in practice in order to allow sorting, performing range queries, and filtering...
We study practical order-revealing encryption (ORE) with a well-defined leakage profile (the information revealed about the plaintexts from their ciphertexts), a direction recently initiated by Chenet...
Order-Revealing Encryption: New Constructions, Applications, and Lower Bounds
order-revealing encryption order-preserving encryption range queries
2016/6/15
In the last few years, there has been much interest in developing methods to search over encrypted data. In the case of range queries, a simple solution is to encrypt the contents of the database usin...
Semantically Secure Order-Revealing Encryption: Multi-Input Functional Encryption Without Obfuscation
functional encryption multilinear maps
2016/1/6
Deciding “greater-than” relations among data items just given their encryptions is at the heart of
search algorithms on encrypted data, most notably, non-interactive binary search on encrypted data.

Order-Revealing Encryption and the Hardness of Private Learning
differential privacy learning theory order-revealing encryption
2015/12/31
An order-revealing encryption scheme gives a public procedure by which two ciphertexts
can be compared to reveal the ordering of their underlying plaintexts. We show how to use
order-revealing encry...
Practical Order-Revealing Encryption with Limited Leakage

2015/12/21
In an order-preserving encryption scheme, the encryption algorithm produces ciphertexts that
preserve the order of their plaintexts. Order-preserving encryption schemes have been studied
intensely i...
