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.

Public key encryption with keyword search and keyword guessing attack: a survey

2016
Searchable encryption is a cryptographic notion which enables users to perform secure searches over encrypted data stored on an untrusted server.‎ Searchable encryption techniques can be divided into two main categories: searchable symmetric encryption (SSE) and public key encryption with keyword search (PEKS).‎ Unlike SSE techniques, PEKS methods are ...

Public-key encryption with keyword search: a generic construction secure against online and offline keyword guessing attacks

Journal of Ambient Intelligence and Humanized Computing, 2019
In public-key setting, the problem of searching for keywords in encrypted data is handled by the notion of  public-key encryption with keyword search (PEKS). An important challenge in designing secure PEKS schemes is providing resistance against variants of  an  attack  known as the keyword  guessing  attack (KGA).

Designated-Senders Public-Key Searchable Encryption Secure against Keyword Guessing Attacks

2017 Fifth International Symposium on Computing and Networking (CANDAR), 2017
To achieve keyword search in secure cloud storage, a public-key encryption with keyword search (PEKS) has been proposed. However, the PEKS is inherently vulnerable to the Keyword Guessing Attack (KGA): Using the public key, anyone including the server can compute the ciphertext of any keyword.

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 ...
