Comments on “Lightweight Multi-User Public-Key Authenticated Encryption With Keyword Search”
Abstract
Xu et al. (IEEE Transactions on Information Forensics and Security 2025) proposed a lightweight multi-user public-key authenticated encryption with keyword search (LM-PAEKS) scheme. In this short note, we demonstrate that keyword information can be leaked from ciphertexts in the scheme. We further note that there are shortcomings in the security proof as well.
