An ElGamal Encryption with Fuzzy Keyword Search on Cloud Environment

by Yilei Wang , Wenyi Bao , Yang Zhao , Hu Xiong , Zhiguang Qin , Hu Xiong
"... Abstract With the continuous development of cloud computing, more and more sensitive data needs to be centrally stored in the cloud storage. For protecting the privacy of data, sensitive data must be encrypted before being outsourced to the server. The traditional PEKS (Public Encryption Keyword Se ..."

Search) enables users to search data by using keywords in the condition of encryption, however, it not only needs the security channel but also tolerates the huge pairing-computation. Although the pairing-free public key encryption with keyword search has been proposed, it can not support fuzzy keyword

Efficient Public Key Encryption with Keyword Search Schemes from Pairings

by Chunxiang Gu, Yuefei Zhu, Yajuan Zhang , 2006
"... Public key encryption with keyword search (PEKS) enables user Alice to send a secret key T_W to a server that will enable the server to locate all encrypted messages containing the keyword W, but learn nothing else. In this paper, we propose a new PKES scheme based on pairings. There is no pairing o ..."

Public Key Encryption with Keyword Search Revisited

by Joonsang Baek, Reihaneh Safiavi-naini, Willy Susilo , 2005
"... The public key encryption with keyword search (PEKS) scheme recently proposed by Boneh, Di Crescenzo, Ostrovsky, and Persiano enables one to search encrypted keywords without compromising the security of the original data. In this paper, we address three important issues of a PEKS scheme, "r ..."

A new trapdoorindistinguishable public key encryption with keyword search

by Yuanjie Zhao , Xiaofeng Chen , Hua Ma , Qiang Tang , Hui Zhu - Journal of Wireless Mobile Networks, Ubiquitous Computing and Dependable Applications , 2012
"... Abstract The public key encryption with keyword search (PEKS) provides a way for users to search data which are encrypted under the users' public key on a storage system. However, the original schemes are based on the unrealistic assumption of a secure channel between the receiver and the serv ..."

Generic Combination of Public Key Encryption with Keyword Search and Public Key Encryption

by Rui Zhang, Hideki Imai
"... Abstract. In this paper, we study the problem of secure integrating public key encryption with keyword search (PEKS) with public key data encryption (PKE). We argue the previous security model is not complete regarding keyword privacy and the previous constructions are secure only in the random orac ..."

Public-Key Encryption with Fuzzy Keyword Search: A Provably Secure Scheme under Keyword Guessing Attack

by Peng Xu, Hai Jin , 2010
"... A lot of interest has been drawn recently into public-key encryption with keyword search (PEKS), which keeps publickey encrypted documents amendable to secure keyword search. However, PEKS resist against keyword guessing attack by assuming that the size of the keyword space is beyond the polynomial ..."

Leakage Resilient ElGamal Encryption

by Eike Kiltz, Krzysztof Pietrzak
"... Abstract. Blinding is a popular and well-known countermeasure to protect public-key cryptosystems against side-channel attacks. The high level idea is to randomize an exponentiation in order to prevent multiple measurements of the same operation on different data, as such measurements might allow th ..."

. In particular, we consider a multiplicatively blinded version of ElGamal public-key encryption where – we prove that the scheme, instantiated over bilinear groups of prime order p (where p−1 is not smooth) is leakage resilient in the genericgroup model. Here we consider the model of chosen-ciphertext security

Searching Keywords with Wildcards on Encrypted Data

by Saeed Sedghi, Peter Van Liesdonk, Svetla Nikova, Pieter Hartel, Willem Jonker
"... Abstract. A hidden vector encryption scheme (HVE) is a derivation of identity-based encryption, where the public key is actually a vector over a certain alphabet. The decryption key is also derived from such a vector, but this one is also allowed to have “⋆ ” (or wildcard) entries. Decryption is pos ..."

Searchable Keyword-Based Encryption

by Dong Jin Park, Juyoung Cha, Pil Joong Lee , 2005
"... To solve the problem of searching on encrypted data, many keyword search schemes have been proposed in recent years. The goal of such schemes is to enable a user to give an untrusted storage server the ability only to test whether an encrypted document contains a few keywords without learning anyt ..."

#cient construction whose security is proved in a random oracle model under the Bilinear Di#e-Hellman Inversion assumption. The scheme is constructed based on the Public Key Encryption with Conjunctive Field Keyword Search scheme in [21] by using a hybrid encryption technique.
