We propose a semi-quantum blind digital signature protocol which can communicate between the classical party and quantum party. And our scheme is guaranteed by GHZ state and semi-quantum key distribution. The application of semi-quantum conception can reduce the computational burden of the communicants. In addition, in order to improving the security of communications between classical and quantum party, we propose a new method to detect eavesdropping. Through the security analysis, we confirm that our protocol is secure and simple to implement with practical existing quantum hardware devices.
