摘要:

代理盲签名在电子投票系统、电子商务系统和网络环境等方面有着广泛的应用。综合考虑现实情形下的通信开销、量子操作复杂性、验证效率等相关因素,提出了一种基于量子W态相干性的量子代理盲签名方案。消息拥有者先将秘密盲化,代理签名者在经过授权后对盲化的消息进行有效签名。方案最大的优势是签名时仅仅需要单粒子测量,并不需要实施任何量子酉变换。此外,与其他主流方案相比,在验证签名和经典通信的效率上也获得了更好地效果。

Abstract:

Proxy blind signature was widely applied to Electronic Voting, Electronic Commerce , and other Network settings. Considering the comprehensive factors of the communication cost, the quantum operation complexity, the verification efficiency, etc., an efficient quantum proxy blind signature scheme based on the correlation of W state is proposed, in which the owner blinds the secret first and then the proxy signer signs the blinded message after authorized. The best advantage of this scheme is that it only needs single-particle measurements in the signature, but not any quantum unitary operation. In addition to, the proposed scheme obtains the higher efficiency in the signature verification and classical communication, compared with the current well-known scheme.

Key words: quantum information;W state;quantum signature;proxy blind signature
