An efficient and secure certificateless searchable encryption scheme against keyword guessing attacks

Journal of Systems Architecture, 2021
Abstract As the wave of data breaches continues crashing down on companies, specially for companies that provide cloud storage services, the data security and privacy have become the main concern of most clients that use this kind of services. Certificateless public key encryption with keyword search (CLPEKS) is a novel cryptographic primitives that ...

A secure attribute based keyword search scheme against keyword guessing attack

2016 8th International Symposium on Telecommunications (IST), 2016
To provide the privacy of the users who receive some computing services from the cloud, the users must encrypt their documents before outsourcing them to the cloud. Computation on outsourced encrypted data in the cloud rises some complexity to the system specially in the case when an entity would like to find some documents related to a special keyword.

Proxy re-encryption conjunctive keyword search against keyword guessing attack

2013 Computing, Communications and IT Applications Conference (ComComAp), 2013
Public key encryption with keyword search enables users to retrieve keywords from encrypted data, which can protect data confidentiality without losing the search operability. However, it is also vulnerable to keyword guessing attacks. In this paper, we propose a conjunctive keywords searchable encryption with designated tester (dPECK) to prevent the ...

Keyword search encryption scheme resistant against keyword-guessing attack by the untrusted server

Journal of Shanghai Jiaotong University (Science), 2014
The user data stored in an untrusted server, such as the centralized data center or cloud computing server, may be dangerous of eavesdropping if the data format is a plaintext. However, the general ciphertext is difficult to search and thus limited for practical usage.

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 PEKS schemes secure against keyword guessing attacks is possible?

Computer Communications, 2009
Byun et al. suggested keyword guessing attacks and showed that some PEKS (public-key encryption with keyword search) schemes are not secure to keyword guessing attacks, when the number of possible keywords is bounded by some polynomial. Abdalla et al. showed that robust PEKS schemes should satisfy consistency which ensures the PEKS schemes fulfil their

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.
