“…Since then, based on the unconditional security characteristics of quantum encryption, quantum digital signature (QDS) has been greatly developed and could be widely used in areas such as government correspondence signatures and electronic transactions in the future. According to the function of signature in different application fields, QDS [5][6][7][8][9][10][11][12] can be divided into the following categories: quantum blind signature, quantum proxy signature (QPS), quantum proxy blind signature and arbitrated quantum signature.…”

We present a new semi-quantum signature protocol which is suitable for participant without quantum capabilities to communicate securely. In addition, the application of EPR steering is first extended to the field of quantum digital signature in our protocol. On the one hand, in order to avoid attacks by attackers, our protocol allows one participant to determine the identity of the other, if the steering conditions for EPR steering are satisfied. On the other hand, original message can be transmitted between participants via EPR steering. Moreover, our scheme is simple to implement and more efficient. The security analysis shows that our protocol can avoid the attack of deny, forgery and Entangle-Measure.
