Abstract: A method, a terminal and a communication system are provided for generating a local interface key. In the disclosure, the terminal generates a variable parameter and sends the generated variable parameter and other parameters for generating the local interface key to a network. The network derives, according to the variable parameter and the parameters for generating the local interface key, the local interface key. The terminal obtains the local interface key from the network so as to use in intercommunication with other device, such as a UICC, or other terminal device. Thus, the security of the intercommunication between the terminal and the other device is ensured.
