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

2021
Public 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

Blockchain-Assisted Public-Key Encryption with Keyword Search Against Keyword Guessing Attacks for Cloud Storage

IEEE Transactions on Cloud Computing, 2021
Cloud storage enables users to outsource data to storage servers and retrieve target data efficiently. Some of the outsourced data are very sensitive and should be prevented for any leakage. Generally, if users conventionally encrypt the data, searching is impeded. Public-key encryption with keyword search (PEKS) resolves this tension.
