Abstract: In this paper，secure circuit evaluation scheme based on Smolin states can be implemented in realistic，highly quantum network with four quantum units.The protocol has one master unit and three slave units.The four units share Smolin states.The order of the qubits of the protocol which be sent to each party should be random.The master unit asks the three slave units to announce the result of their measurement，and checks together.The protocol proves to secure against three cheating strategy，two cheating strategy，one cheating strategy.It has been theoretically proved that an eavesdropper invariably introduce errors in communication network，it must find.The secure circuit evaluation scheme guarantee the security of the network.
