Summary:A semi-quantum bi-signature scheme based on W states is designed, in which two signers sign the same message. The unconditional security of the new semi-quantum bi-signature scheme is guaranteed with the teleportation of W states and semi-quantum key distribution (SQKD) protocol. From the aspects of hardware requirement and efficiency, the proposed semi-quantum bi-signature scheme is more efficient and convenient than many typical quantum signature schemes.
