Abstract
This study points out that a dishonest party in Yang and Wen's arbitrated quantum signature scheme [Opt. Comm. 283, (2010) 3198-3201] can reveal the other party's secret key without being detected by using the Trojan-horse attacks. Accordingly, the security requirements of a quantum signature, i.e. unforgeability and undeniability, may not be satisfied in their scheme.
