SDKSE-KGA: A Secure Dynamic Keyword Searchable Encryption Scheme Against Keyword Guessing Attacks [PDF]
IFIP Advances in Information and Communication Technology, 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 ...

Keyword Guessing Attacks on Some Proxy Re-Encryption with Keyword Search Schemes
2021Public 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

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.

A secure attribute based keyword search scheme against keyword guessing attack
2016 8th International Symposium on Telecommunications (IST), 2016To 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.

Constructing PEKS schemes secure against keyword guessing attacks is possible?
Computer Communications, 2009Byun 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

Proxy re-encryption conjunctive keyword search against keyword guessing attack
2013 Computing, Communications and IT Applications Conference (ComComAp), 2013Public 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 ...

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), 2017With 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 ...
