摘　　要：In this paper, we realize Shamir＇s no-key protocol via quantum computation of Boolean functions and a private quantum channel. The proposed quantum no-key protocol has three rounds and provides mutual data origin authentication. Random Boolean functions are used to create entanglement and guarantee that any adversary without keys cannot pass the authentication. Thus, our protocol can resist the manin-the-middle attack. A security analysis has shown that pieces of ciphertexts of the three rounds are completely mixed state. This property ensures no adversary can get any information about the sent message or authentication keys. Therefore, our protocol is unconditionally secure and its authentication keys can be reused.In this paper, we realize Shamir＇s no-key protocol via quantum computation of Boolean functions and a private quantum channel.
