The invention provides a method for establishing a safe channel, a data protection method thereof, and a method for updating a secret key of the safe channel. During the handshake process of establishing a secure communication channel between the terminal and the server, both parties check whether the secure communication channel has been successfully established and the key has not changed, and check whether the other party's certificate is cached. If the relevant data has been cached, the data and process transmitted in the handshake process between the two parties can be reduced, so as to achieve the characteristics of the packet domain communication of the mobile communication network and ensure the data security in the data communication process between the terminal and the server. Minimize the establishment time of the two parties to establish a secure communication channel, and achieve the purpose that the two parties do not have to maintain the TCP chain all the time.
