Disclosed is a method for allocating a communication key based on an Android intelligent mobile terminal. By establishing a universal secret communication platform on the bottom layer of an Android operating system, an intelligent mobile terminal is equipped with the functions of being able to interact with a secret communication support network, receiving a two-level key and using a received service key after decrypting same, thereby being able to provide universal bottom-layer support for a VoIP secret call, a secret short message, a secret video call, file encryption transmission, secure mobile payment and other communication services which require secrecy support. The secret communication support network provides the service keys required for various communication services for a reformed intelligent mobile terminal, and after obtaining the service keys, the intelligent mobile terminal uses same to conduct the secret communication. |

1. A method for distributing communication keys based on an Android intelligent mobile terminal, comprising:
(1) establishing a universal secret communication platform in bottom layers of an Android operating system, invoking Application Programming Interfaces (APIs) of the universal secret communication platform in source codes of communication software programs in an application layer, compiling modified source codes of the Android operating system into an image file, and writing the image file into the intelligent mobile terminal; (2) directly connecting the intelligent mobile terminal to a key terminal in a secret communication support network, downloading shared keys between the intelligent mobile terminal and the secret communication support network, storing the shared keys into the intelligent mobile terminal, and disconnecting the intelligent mobile terminal with the key terminal after the shared keys are downloaded; (3) after a communication service is initiated, generating, by the intelligent mobile terminal, a service key acquisition thread by invoking the APIs of the universal secret communication platform in the bottom layers of the system, and requesting service keys for the communication from the secret communication support network; (4) distributing, by the secret communication support network, the service keys for the communication to the intelligent mobile terminal participating in the communication, after the request for the service keys is received; (5) receiving, by the intelligent mobile terminal, the service keys for the communication from the secret communication support network by invoking the APIs of the universal secret communication platform in the bottom layers of the system; and storing, by the intelligent mobile terminal, the service keys in a memory space of the intelligent mobile terminal; and (6) performing, by the intelligent mobile terminal, a secret communication by using the service keys. |
