Secure searchable public key encryption scheme against keyword guessing attacks

IEICE Electronics Express, 2009
Byun et al. firstly proposed off-line keyword guessing (KG)attacks and proved that some searchable public key encryption (PEKS)schemes are insecure against these attacks. They supposed an open problem on how to construct PEKS schemes secure against keyword guessing attacks. In this letter, we answer this question affirmatively.

SDKSE-KGA: A Secure Dynamic Keyword Searchable Encryption Scheme Against Keyword Guessing Attacks [PDF]

, 2019
A number of searchable encryption schemes have been widely proposed to solve the search problem in ciphertext domain. However, most existing searchable encryption schemes are vulnerable to keyword guessing attacks. During keyword guessing attacks, with the help of the cloud, an adversary will learn what keyword a given trapdoor is searching for, which ...

Comment on “Expressive Public-Key Encryption With Keyword Search: Generic Construction From KP-ABE and an Efficient Scheme Over Prime-Order Groups”

IEEE Access
The public key encryption with keyword search (PEKS) scheme is a cryptographic primitive that allows a cloud server to search for a ciphertext without knowing the corresponding keyword used in the search.

A Secure Data-Sharing Model Resisting Keyword Guessing Attacks in Edge–Cloud Collaboration Scenarios

Electronics
In edge–cloud collaboration scenarios, data sharing is a critical technological tool, yet smart devices encounter significant challenges in ensuring data-sharing security. Attribute-based keyword search (ABKS) is employed in these contexts to facilitate fine-grained access control over shared data, allowing only users with the necessary privileges to ...

Trapdoor Privacy in Public Key Encryption With Keyword Search: A Review

IEEE Access, 2022
The public key encryption with keyword search (PEKS) scheme allows searches to be performed over ciphertext by a server in a public-key setting. The PEKS scheme suffers from a major drawback which is keyword guessing attack.
