Public Key Encryption with Authorized Keyword Search
2016Public key encryption with keyword search PEKS provides an elegant mechanism for a user to identify the specific encrypted data. PEKS protects data against disclosure while making it searchable. In this paper, we propose a new cryptographic primitive called public key encryption with authorized keyword search PEAKS.

Public Key Encryption with Ranked Multi-keyword Search
2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013It is necessary for the cloud server to allow multi-keyword query and provide result ranking to effectively retrieve data from the large number of encrypted data stored in the cloud storage. A related work that support privacy preserving ranked multi-keyword search over encrypted cloud data (MRSE) is not in public-key model.

Decryptable Public Key Encryption with Keyword Search Schemes
International Journal of Digital Content Technology and its Applications, 2010A public key encryption with keyword search (PEKS) scheme does not allow the user to decrypt the encrypted keyword or decrypt the encrypted massage. This "no-decryption" property also limits the applicability of a PEKS scheme. Fuhr and Paillier also left an open problem on how to come up with a decryptable PEKS which security does not rely on random ...

Public-Key Encryption with Keyword Search from Lattice
2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing, 2013Public-keyword encryption with keyword search (PEKS) is a newly emerged primitive which can provide data search functionality that is absent in traditional public-key encryption (PKE). In this work, we propose the first provably secure PEKS from lattice.

Public Key Encryption with Multi-keyword Search
2012Since the notion of Public-Key Encryption with Keyword Search (PEKS) scheme was proposed, many revisions and extensions have been given. Public-Key Encryption with Multi-Keyword Search(PEMKS) is one of these extensions, which means that the receiver could query subset keywords of all the keywords embedded in the ciphertext.

Revocable Public Key Encryption with Authorized Keyword Search
2019 IEEE 3rd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2019In this paper, we propose a revocable public key encryption with authorized keyword search (RPEAKS) scheme. In RPEAKS, data and keywords are encrypted with one public key, users without corresponding private key need authorization from the manager if they want to search through the ciphertexts.

Public Key Encryption with Distributed Keyword Search
2016In this paper we introduce Threshold Public Key Encryption with Keyword Search TPEKS, a variant of PEKS where the search procedure for encrypted keywords is distributed across multiple servers in a threshold manner. TPEKS schemes offer stronger privacy protection for keywords in comparison to traditional PEKS schemes.

A new public key encryption with temporary keyword search
2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, 2010The public key encryption with keyword search (PEKS) scheme recently proposed by Boneh et al enables one to search encrypted keywords without compromising the security of the original data. In Joonsang's paper, they proposed a important issue of refreshing keyword in PEKS.

Public key encryption with conjunctive keyword search on lattice
Journal of Information Security and Applications, 2020Abstract Outsourcing data in cloud storage is gaining popularity recently. For protecting data privacy, the data should be encrypted, and it is thus critical to provide search services for encrypted outsourced data. However, it becomes a problem about how to retrieve encrypted data while protecting data privacy at the same time. Therefore, public key

Generic Combination of Public Key Encryption with Keyword Search and Public Key Encryption
2007In 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 oracle model.
