SPKSE: secure public key searchable encryption withstand keyword guessing attacks [PDF]
Scientific ReportsAbstract Public Key Searchable Encryption (PKSE) enables secure keyword searches over encrypted data, making it a critical tool for outsourced storage systems. However, existing PKSE schemes remain vulnerable to two types of keyword guessing attacks: offline attacks, where adversaries leverage the public key to systematically generate and test ...

Off-Line Keyword Guessing Attacks on Searchable Encryption with Keyword-Recoverability
IEICE Transactions on Information and Systems, 2010 In 2009, Jeong et al. proposed a new searchable encryption scheme with keyword-recoverability which is secure even if the adversaries have any useful partial information about the keyword. They also proposed an extension scheme for multi-keywords. However, this paper demonstrates that Jeong et al.'s schemes are vulnerable to off-line keyword guessing ...

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 ...

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.

ABKS-SKGA: Attribute-based keyword search secure against keyword guessing attack
Computer Standards & Interfaces, 2021 Abstract In order to guarantee security and privacy of sensitive data, attribute-based keyword search (ABKS) enables data owners to upload their encrypted data to cloud servers, and authorizes intended data users to retrieve it. Meanwhile, ABKS outsources heavy search work to cloud servers, which makes ABKS adaptive to mobile computing environment ...

A Novel Methodology to Mitigate Keyword Guessing Attack using Keyword and Signature Hash
Indian Journal of Science and Technology, 2015 The importance of electronic data and its rapid growth leads to gradual increase to the data usage over the network servers and on the other side high priority is needed for the data security and privacy. The existing keyword search schemes for data retrieval from the centralized storage uses keyword as a valid parameter.

Verifiable Searchable Encryption Framework Against Insider Keyword-Guessing Attack in Cloud Storage
IEEE Transactions on Cloud Computing, 2022 Searchable encryption (SE) allows cloud tenants to retrieve encrypted data while preserving data confidentiality securely. Many SE solutions have been designed to improve efficiency and security, but most of them are still susceptible to insider Keyword-Guessing Attacks (KGA), which implies that the internal attackers can guess the candidate keywords ...

Nitric Oxide Tunes Secreted Metabolite Bioactivity
Molecular Microbiology, EarlyView.Pseudomonas aeruginosa produces phenazine metabolites that can react with nitric oxide (·NO) to form nitrosylated compounds. The formation of these metabolites results in rapid loss in P. aeruginosa viability and diminishes phenazine antimicrobial activity against other organisms, including Staphylococcus aureus. ABSTRACT The radical nitric oxide (·NO)
