Abstract

Cheng and Meng (IEEE Transactions on Information Forensics and Security 2024) introduced server-aided public key authenticated encryption with keyword search (SA-PAEKS). In this short note, we give general attacks that the cloud server (tester) can obtain keyword information from both a ciphertext and a trapdoor.
