Proxy signature is a special signature which provided the signer can delegate their signing capability to others. The proxy signature provides that the original signer can delegate their signing permission to a proxy signer, and the proxy signer can replace the original signer to sign the message. In this paper, the authors 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.
