| Abstract: | In this paper, we propose an improved proxy blind signature scheme based on controlled quantum teleportation. Five-qubit entangled state functions as quantum channel. We use physical characteristics of quantum mechanics to implement signature, delegation and verification. Furthermore, quantum key distribution (QKD) protocol and one-time pad are adopted in this scheme. Like classical signature protocols, our scheme can be used in many application scenarios, such as e-government and e-business. |
