Generic Construction of Dual‐Server Public Key Authenticated Encryption With Keyword Search
IET Information Security, Volume 2025, Issue 1, 2025.In this paper, we propose a generic construction of dual‐server public key authenticated encryption with keyword search (DS‐PAEKS) from PAEKS, public key encryption, and signatures. We also show that previous DS‐PAEKS scheme is vulnerable by providing a concrete attack. That is, the proposed generic construction yields the first DS‐PAEKS schemes.
