Lattice-Based Searchable Encryption With Keywords Revocable and Bounded Trapdoor Exposure Resistance
IEEE Access, 2019 Searchable encryption plays a vital role in keeping data privacy of current cloud storage. Considering the security threat of trapdoor exposure, Emura et al. introduced a formal definition of keywords revocable public-key encryption with keywords search (

StopGuess: A framework for public-key authenticated encryption with keyword search
Computer Standards & InterfacesPublic key encryption with keyword search (PEKS) allows users to search on encrypted data without leaking the keyword information from the ciphertexts. But it does not preserve keyword privacy within the trapdoors, because an adversary (e.g., untrusted server) might launch inside keyword-guessing attacks (IKGA) to guess keywords from the trapdoors.

Searchable encryption with randomized ciphertext and randomized keyword search
Journal of Mathematical CryptologyThe notion of public-key encryption with keyword search (PEKS) was introduced to search over encrypted data without performing any decryption. In this article, we propose a PEKS scheme in which both the encrypted keyword and the trapdoor are randomized ...

A blockchain searchable encryption scheme for legal data shared by multiple parties
Journal of Applied Science and EngineeringThe national judicial system has put forward higher requirements for the sharing of legal data, but existing legal data sharing schemes still have some problems, such as weak data security, unrestricted user access.

Public Key Encryption and Keyword Search Mapping
This work addresses a difficult method for searching for crucial keywords for mixed cloud statistics (MRSE), which is a first step towards enabling secure cloud data processing. Among the different meanings of multiple terms, we choose the relevant concept of "relational coherence".

Public-Key Authenticated Encryption with Keyword Search Made Easy
IACR Communications in CryptologyPublic-key searchable encryption allows keyword-associated tokens to be used to test if a ciphertext contains specific keywords. Due to the low entropies of keywords, the token holder can create ciphertexts from candidate keywords and test them using the token in hand to recover the keywords, known as inside keyword guessing attacks (IKGA). Public-

On the security of the CLSV PAEKS scheme
Journal of Mathematical CryptologyCalderini, Longo, Sala and Villa (Journal of Mathematical Cryptology 2024) proposed a public key encryption with keyword search (PKES) scheme which we call the CLSV scheme. They claim that the scheme provides Ciphertext-Indistinguishability (CI) security

Multi-keyword public key searchable encryption scheme with pattern hiding
Tongxin xuebaoTo address the limitations of existing multi-user searchable encryption (SE) schemes that fail to hide access patterns, search patterns, and resist keyword guessing attacks, a novel public-key searchable encryption scheme was proposed supporting multi ...
