• Title: On the lightweight authenticated semi-quantum key distribution protocol without Trojan horse attack
• Authors: Jun Gu and Tzonelih Hwang
• Abstract summary: We propose a lightweight authenticated semi-quantum key distribution protocol for a quantum participant to share a secret key with a classical participant. An attacker can use a modification attack to make both participants share a wrong key without being detected.

• Abstract: Recently, Tsai et al. (Laser Phys. Lett. 17, 075202, 2020) proposed a lightweight authenticated semi-quantum key distribution protocol for a quantum participant to share a secret key with a classical participant. However, this study points out that an attacker can use a modification attack to make both participants share a wrong key without being detected. To avoid this problem, an improvement is proposed here.
