Keyword guessing attacks on a public key encryption with keyword search scheme without random oracle and its improvement

Information Sciences, 2019
Abstract Public key encryption with keyword search (PEKS) is a useful paradigm that enables a user to delegate searching capabilities on publicly encrypted data to an untrusted third party without revealing the data contents. In 2013, Fang et al.

Public key encryption with conjunctive keyword search secure against keyword guessing attack from lattices

Transactions on Emerging Telecommunications Technologies, 2018
AbstractPublic key encryption With keyword search (PEKS) enables a cloud server (CS) to get the search trapdoor to identify ciphertext containing the target keyword without decrypting the ciphertext or knowing the target keyword. With the advent of mobile cloud computing, PEKS has ushered in an era of new development opportunities and new challenges ...

A Survey on Encryption Framework Against Insider Keyword-Guessing Attack in Cloud Storage

Advances in Computational Intelligence in Materials Science, 2023
A key component of data security in cloud computing systems is encryption. Encryption might not be enough, though, to shield sensitive data from hostile intrusions. One such attack is the keyword guessing attack, in which an attacker uses a variety of techniques to attempt to decipher a term from the encrypted data.

Off-Line Keyword Guessing Attacks on Recent Keyword Search Schemes over Encrypted Data

2006
A keyword search scheme over encrypted documents allows for remote keyword search of documents by a user in possession of a trapdoor (secret key). A data supplier first uploads encrypted documents on a storage system, and then a user of the storage system searches documents containing keywords while insider (such as administrators of the storage system)

Hidden policy ciphertext-policy attribute-based encryption with keyword search against keyword guessing attack

Science China Information Sciences, 2016
Attribute-based encryption with keyword search (ABKS) enables data owners to grant their search capabilities to other users by enforcing an access control policy over the outsourced encrypted data. However, existing ABKS schemes cannot guarantee the privacy of the access structures, which may contain some sensitive private information.

Constructing designated server public key encryption with keyword search schemes withstanding keyword guessing attacks

International Journal of Communication Systems, 2018
Summary Designated server public key encryption with keyword search (dPEKS) removes the secure channel requirement in public key encryption with keyword search (PEKS). With the dPEKS mechanism, a user is able to delegate the search tasks on the ciphertexts sent to him/her to a designated storage server without leaking the ...

Keyword guessing attacks on secure searchable public key encryption schemes with a designated tester

International Journal of Computer Mathematics, 2013
The first searchable public key encryption scheme with designated testers dPEKS known to be secure against keyword guessing attacks was due to Rhee et al. [H.S. Rhee, W. Susilo, and H.J. Kim, Secure searchable public key encryption scheme against keyword guessing attacks, IEICE Electron. Express 65 2009, pp. 237–243].

Cloud-Assisted Privacy Protection for Data Retrieval Against Keyword Guessing Attacks

2020
Machine learning is more closely linked to data privacy and has obtained rapid development in recent years. As for data privacy, searchable encryption (SE) is widely used as a ciphertext search technology, protecting the privacy of users. However, existing schemes usually support single keyword search, so the remote cloud server (CS) may return some ...
