Keyword Guessing Attacks on Some Proxy Re-Encryption with Keyword Search Schemes

2021
Public key encryption with keyword search (PEKS) is a practical cryptographic paradigm that enables one to search for the encrypted data without compromising the security of the original data. It provides a promising solution to the encrypted data retrieval issue in public key cryptosystems. As a combination of PEKS and proxy re-encryption (PRE), proxy

Blockchain-Assisted Public-Key Encryption with Keyword Search Against Keyword Guessing Attacks for Cloud Storage

IEEE Transactions on Cloud Computing, 2021
Cloud storage enables users to outsource data to storage servers and retrieve target data efficiently. Some of the outsourced data are very sensitive and should be prevented for any leakage. Generally, if users conventionally encrypt the data, searching is impeded. Public-key encryption with keyword search (PEKS) resolves this tension.

Conjunctive Keywords Searchable Encryption Scheme Against Inside Keywords Guessing Attack from Lattice

2020
Public-key encryption with conjunctive keywords search (PECKS) is an extension of public-key encryption with keywords search (PEKS), which can realize the efficient search of the encrypted data stored in the cloud server and keep the privacy of these data during the search phase.

Online/offline attribute-based encryption with keyword search against Keyword Guessing Attack

2017 3rd IEEE International Conference on Computer and Communications (ICCC), 2017
With the exposure of security events in cloud storage, encrypting data before uploading has become the most favorable choice for cloud users, which makes search on encrypted data an important issue. Attribute-based encryption with keyword search (ABKS), which achieves data access control and search on encrypted data at the same time, has risen in ...

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 ...

Off-Line Keyword Guessing Attacks on Recent Public Key Encryption with Keyword Search Schemes

2008
The Public Key Encryption with Keyword Search Scheme (PEKS) was first proposed by Boneh et al. in 2004. This scheme solves the problem of searching on data that is encrypted using a public key setting. Recently, Baek et al. proposed a Secure Channel Free Public Key Encryption with Keyword Search (SCF-PEKS) scheme that removes the secure channel for ...

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 ...

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)

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.
