摘要：Proxy signature is a special signature which provided the signer can delegate his signing capability to others. The proxy signature provides that the original signer can delegate his signing permission to a proxy signer, and the proxy signer can replace the original signer to sign the message. In this paper, we propose a proxy signature scheme based on ideas from classical proxy signature schemes and quantum cryptography. The scheme is implemented by Bell states and a symmetrical quantum key cryptosystem. Compile with classical proxy signature schemes, the new scheme can guarantee the security by using quantum key distribution and one-time pads. And it also can prove that the scheme have the characteristics of non-counterfeit, non-disavowal and traceability. Furthermore, the new scheme uses a special quantum encryption to ensure the receiver cannot forge the signature. The validity of the new scheme can be verified, and it is a secure proxy signature scheme.
