Abstract

Lin et al. proposed a mediated semi-quantum key distribution protocol in 2019. This study shows that Lin et al.'s protocol has a security loophole that could mount to the collective attack to reveal some information about the secret key without being detected. To overcome this problem, an improved protocol is proposed and its security is proven.
