Generic Adaptively Secure Searchable Phrase Encryption
In recent years searchable symmetric encryption has seen a rapid increase in query expressiveness including keyword, phrase, Boolean, and fuzzy queries. With this expressiveness came increasingly complex constructions. Having these facts in mind, we present an efficient and generic searchable symmetric encryption construction for phrase queries. Our construction is straightforward to implement,...
متن کاملAdaptively Secure Computationally Efficient Searchable Symmetric Encryption
Searchable encryption is a technique that allows a client to store documents on a server in encrypted form. Stored documents can be retrieved selectively while revealing as little information as possible to the server. In the symmetric searchable encryption domain, the storage and the retrieval are performed by the same client. Most conventional searchable encryption schemes suffer from two dis...
متن کاملUC-Secure Searchable Symmetric Encryption
For searchable symmetric encryption schemes (or symmetrickey encryption with keyword search), the security against passive adversaries (i.e. privacy) has been mainly considered so far. In this paper, we first define its security against active adversaries (i.e. reliability as well as privacy). We next formulate its UC-security. We then prove that the UCsecurity against non-adaptive adversaries ...
متن کاملTowards Provably Secure Efficiently Searchable Encryption
Traditional encryption systems are designed in such a way that either the whole datais decrypted, if the encryption and decryption keys match, or nothing is decryptedotherwise. However, there are applications that require a more flexible encryptionsystem which supports decrypting data partially. Searchable encryption is a tech-nique that provides functionalities to decrypt data ...
متن کاملAdaptively Secure Broadcast Encryption with Short Ciphertexts
We propose an adaptively secure broadcast encryption scheme with short ciphertexts, where the size of broadcast encryption message is fixed regardless of the size of the broadcast group. In our proposed scheme, members can join and leave the group without requiring any change to public parameters of the system or private keys of existing members. Our construction has a twofold improvement over ...
