Abstract: This paper consider the problem of key distribution between any two users in a network. A proto- col for quantum key distribution between any two users in a network is proposed, its quantum logical gate scheme is given. The security of the situation that exists an eavesdropper (Eve) or CA is unauthentic is dis- cussed respectively. It is proved that this scheme can withstand the attack effectively. This scheme use only hadmard gate and CNOT gate, it’s easy to be realized in real physical system.
