摘要
量子多重代理签名协议利用Bell态和单量子比特逻辑门之间的逻辑关系,简单高效地实现多重代理签名操作。协议不受代理签名人数、先后顺序的限制,且操作简单,在现有技术条件下完全可以实现。协议的正确性和安全性分析表明它是一个安全的、可实现的量子多重代理签名协议。
The logical relationship between Bell state and single quantum bit logic gate is used in quantum multi-proxy signature protocol. Multiple-proxy signature operation is realized simply and efficiently. The protocol is not restricted by the number and sequence of proxy signers, and the operation is simple. It can be realized completely in the existing technical conditions. The correctness and security analysis of the protocol shows that it is a secure and achievable quantum multi-proxy signature protocol.
