Abstract:

Based on quantum properties, a multi-proxy blind signature scheme was proposed. In the scheme, the owner of the message transform message into single quantum state according to corresponding relation between the single quantum state and the message. Then he completes blind message by unitary operation according to the secret key. Proxy signers use unitary transformation of single quantum to complete signature and verification. The scheme does not need to use multi particle entangled quantum states and Verifier Only need to measure single quantum state when verifying the signature. The process is simple and efficient process, at the same time, the information of the signature does not become large with the increase of the signer. The deleting and adding of the proxy signer is easy to operate. The security analysis of the scheme shows that it is a secure and achievable quantum multi-proxy blind signature scheme.

Key words: quantum information, quantum signature, multi-proxy blind signature
