Research and Progress of Order Preserving Encryption
摘要
Abstract
The new term of cloud computing evolves from several concepts such as distributed computing,parallel computing,and grid computing,and achieves the long dreamed vision of computing as an infrastructure. With the rapid development of cloud computing, an increasing number of users prefer to outsource data to the cloud in order to mitigate the burden of local storage. Because the cloud server is untrusted, data should be encrypted before outsourcing to protect the confidentiality. However,the traditional encryption scheme destroys the order property which enables the range query. Order preserving encryption(OPE)is an encryption scheme where the sort order of ciphertexts match the sort order of the corresponding plaintexts. It can protect the confidentiality of data and allow other applications to process queries over encrypted data efficiently. The best possible security of OPE is IND-OCPA which says the encryption schemes reveal nothing except the order of plaintexts. Recently, the design of OPE gets more and more diversified. Numerous OPE schemes based on data structure have been proposed to improve the efficiency and usability. This paper first reviews the development history of OPE and an expansion order revealing encryption(ORE),discusses the security and practical of these schemes, and introduces some latest research achievements. This paper also presents some problems need to be solved in this direction. Finally,an attempt is given to foresee the future research directions in OPE.关键词
