This paper proposes a new semi-quantum key distribution protocol, allowing two “classical” participants without sophisticated quantum capability to establish a shared secret key under an untrusted third party (a quantum server). The proposed protocol is free from several well-known attacks. Furthermore, the efficiency is better than the existing three-party SQKD protocol in which the classical participants must have the quantum measurement capability.
