Generic Construction of Public-Key Authenticated Encryption with Keyword Search Revisited
K Emura - IEICE Transactions on Fundamentals of Electronics …, 2024 - search.ieice.org
Public key authenticated encryption with keyword search (PAEKS) has been proposed,
where a sender's secret key is required for encryption, and a trapdoor is associated with not
only a keyword but also the sender. This setting allows us to prevent information leakage of
keyword from trapdoors. Liu et al.(ASIACCS 2022) proposed a generic construction of
PAEKS based on word-independent smooth projective hash functions (SPHFs) and PEKS.
In this paper, we propose a new generic construction of PAEKS, which is more efficient than …

Generic construction of public-key authenticated encryption with keyword search revisited: Stronger security and efficient construction
K Emura - Proceedings of the 9th ACM on ASIA Public-Key …, 2022 - dl.acm.org
Public-key encryption with keyword search (PEKS) does not provide trapdoor privacy, ie,
keyword information is leaked through trapdoors. To prevent this information leakage, public
key authenticated encryption with keyword search (PAEKS) has been proposed, where a
sender's secret key is required for encryption, and a trapdoor is associated with not only a
keyword but also the sender. Liu et al.(ASIACCS 2022) proposed a generic construction of
