Semiquantum proxy blind signature based on quantum teleportation
In this paper,we propose a novel semiquantum proxy blind signature scheme using quantum teleportation based on x states,where the original message owner,proxy signer,and third party are quantum participants with complete quantum capabilities,while the original signer and signature verifier are semiquantum participants with limited quantum capabilities.Our protocol not only has complete blindness,unforgeability,and nonrepudiation,but it also resists the attack behavior of an eavesdropper.Because of the limited quantum capabilities of the original signer and signature verifier,our protocol does not require them to prepare and measure the quantum superposition and quantum entangled states when used in practical applications.Hence,our protocol can reduce the burden of quantum state preparation and measurement for the original signer and signature verifier.
