摘　　要：零知识证明是指证明者使验证者确信证明者拥有某一个秘密值,而证明者没有向验证者泄漏关于该秘密值的任何有用信息.其优点是在证明了自己身份的同时,还确保了有用信息不泄露,有效防止了他人冒充.经典的零知识证明均是基于计算复杂性的.用量子安全通信的传输方式,设计了一套在群组中实现的量子零知识证明方案.Zero knowledge protocol is a basic method of cryptography, which means that the certifier owns a secret ,and it doesn＇t reveal any other useful information about the secret to verifier when authenticated. The advantage is to keep its identity recognized without being substituted and useful information not revealed. However,the presently known typical zero knowledge proof is based on computing complexity. According to the basic thought of classical zero knowledge protocol, a scheme for quantum zero knowledge protocol in a group using a mode of quantum secure communication is designed.
