Constructing Confidential Channels from Authenticated Channels -- Public-Key Encryption Revisited

by Sandro Coretti, Ueli Maurer, Björn Tackmann , 2013
"... The security of public-key encryption (PKE), a widely-used cryptographic primitive, has received much attention in the cryptographic literature. Many security notions for PKE have been proposed, including several versions of CPA-security, CCA-security, and non-malleability. These security notions ar ..."

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 ..."

Generating Searchable Public-Key Ciphertexts with Hidden Structures for Fast Keyword Search

by Member, IEEE Peng Xu , Member, IEEE Qianhong Wu , Member, IEEE Wei Wang , Willy Susilo , Senior Member, IEEE Josep Domingo-Ferrer , Fellow, IEEE Hai Jin
"... Abstract-Existing semantically secure public-key searchable encryption schemes take search time linear with the total number of the ciphertexts. This makes retrieval from large-scale databases prohibitive. To alleviate this problem, this paper proposes Searchable Public-Key Ciphertexts with Hidden ..."

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 ..."

construction hides both the plaintext and public key used for encryption. We prove security in a selective model, under the decision linear assumption. 1

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.

Generic Construction of Certificate Based Encryption from Certificateless Encryption Revisited

by Wei Gao A, Guilin Wang C, Kefei Chen A, Xueli Wang D
"... Certificateless public key encryption (CLE) and certificate based encryption (CBE) are two novel public key cryptographic primitives requiring no authenticity verification of the recipient’s public key. Both of them are motivated to simultaneously solve the heavy certificate management problem inher ..."

Privacy Preserving Revocable Predicate Encryption Revisited

by Kwangsu Lee, Intae Kim, Seong Oun Hwang
"... Predicate encryption (PE) that provides both the access control of ciphertexts and the privacy of ciphertexts is a new paradigm of public-key encryption. An important application of predicate encryption is a searchable encryption system in a cloud storage, where it enables a client to securely outso ..."

Anonymous Hierarchical Identity-Based Encryption (Without Random Oracles). In: Dwork

by Xavier Boyen , Brent Waters - CRYPTO 2006. LNCS, , 2006
"... Abstract We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the mild Decision Linear complexity assumption in bilinear groups. The system is efficient and practical, with sm ..."

Efficiently-Searchable and Deterministic Asymmetric Encryption
