Consult Fig. 4, the encryption method flow chart of the multimode mobile communication terminal that provides for second embodiment of the invention, concrete steps are as described below.
Step S401, the communication pattern that selection is used in having the mobile communication terminal of at least two kinds of communication patterns.
According to the communication needs, a certain communication pattern can be selected, reception, transmission information under this communication pattern in multimode mobile communication terminal.For example, have at the same time in the mobile phone of CDMA, two kinds of communication patterns of GSM, select the cdma communication pattern.
Step S402, calling mobile communication terminal transmission comprise the information of called mobile communication terminal sign to cipher key center.
Calling mobile communication terminal is carried out relevant registration with called mobile communication terminal in communications service provider's cipher key center.The calling mobile communication terminal transmission that makes a call comprises the information of called mobile communication terminal sign to cipher key center.
Step S403, cipher key center are carried out authentication to calling mobile communication terminal.
Cipher key center generates a parameter at random, sends to calling mobile communication terminal.After calling mobile communication terminal is received this parameter, according to this calculation of parameter authenticating result numerical value, with the authenticating result numerical value " return " key" center that obtains, cipher key center compares the authenticating result numerical value that receives and the authenticating result numerical value of storage inside, as unanimity, then authentication success; As inconsistent, failed authentication, cipher key center sends the information that service can not be provided and arrives this calling mobile communication terminal.
Step S404, cipher key center are carried out authentication to called mobile communication terminal.
Cipher key center identifies according to called mobile communication terminal, gets access to called mobile communication terminal address route.Cipher key center generates a parameter at random, sends to called mobile communication terminal.After called mobile communication terminal is received this parameter, according to this calculation of parameter authenticating result numerical value, with the authenticating result numerical value " return " key" center that obtains, cipher key center compares the authenticating result numerical value that receives and the authenticating result numerical value of storage inside, as unanimity, then authentication success; As inconsistent, failed authentication, cipher key center sends can not provide the information of service to calling mobile communication terminal.
Step S405, cipher key center generate the encryption key that is used for this conversation.
Cipher key center judges whether that according to agreement needs are provided with new encryption key for this conversation, and in this way, cipher key center generates an encryption key at random; As not, cipher key center is transferred this calling mobile communication terminal encryption key that last time, conversation was used.
Step S406, cipher key center are carried out encryption to the encryption key that generates.
The cipher key center key that uses public-key carries out encryption to encryption key.
Encryption key after step S407, cipher key center will be encrypted is sent to calling mobile communication terminal and called mobile communication terminal.
Calling mobile communication terminal and called mobile communication terminal are saved in internal storage device after the encryption key that receives is decrypted processing.
Step S408, mobile communication terminal use above-mentioned encryption key to the communication information that this communication pattern sends down, receives encrypt, decryption processing.
Calling mobile communication terminal and called mobile communication terminal use the encryption key of preserving that the communication information that communication pattern sends is down encrypted, and simultaneously the communication information that receives are decrypted.
Encryption key of the present invention is generated at random by cipher key center, and only is used for this conversation, even this encryption key is stolen or is open like this, also can not cause adverse consequences to communicating pair, improves the fail safe of communicating pair.
The present invention also can generate the encryption key that is used for this conversation by calling mobile communication terminal and called mobile communication terminal, re-use this encryption key to the information that communication terminal sends, receives encrypt, decryption processing, improve the fail safe of conversing between the communication terminal.
