Fig. 4 is the message flow schematic diagram of present embodiment.As shown in Figure 4, in conjunction with Fig. 2, present embodiment realizes that the memory card function service method may further comprise the steps:
Step 401～step 402: terminal equipment sends service function type requests message to the interface proxy module, the feature list that the interface proxy module will record service function title and function number returns to terminal equipment, terminal equipment is according to the service function title that the user selects, and obtains function corresponding number from feature list.
In the present embodiment, can be in advance for each service module function is provided with a function number, the service function title of all service module functions in the storage card and corresponding function number are recorded in the feature list.Described feature list can be kept in the interface proxy module, also can be kept at earlier in the memory module, when storage card powers on, reads into from memory module in the interface proxy module again.
If terminal equipment has obtained this feature list in advance, then need not from the interface proxy module, to obtain feature list again, promptly can omit step 401 and step 402.
Step 403: terminal equipment sends the file encryption request message to the interface proxy module, carries the function number of file encryption-decryption module in the described file encryption request message.
Encryption request message described here is exactly a kind of service function request message.
Step 404: the interface proxy module determines that according to function with number corresponding service module function of function be the file encryption-decryption module number from feature list, and the interface proxy module sends the startup request message to the file encryption-decryption module again.
Step 405: the file encryption-decryption module receives and starts after the request message, carries out self initialization procedure, returns the startup response message to interface proxy then.
Step 406: the interface proxy module is returned the encryption request response to terminal equipment after receiving the startup response message that the file encryption-decryption module returns again.
Step 407～step 408: the file encryption-decryption module sends secret key request message by the interface proxy module to terminal equipment, and terminal equipment returns to the file encryption-decryption module with key by the interface proxy module.
Step 409～step 411: terminal equipment will need ciphered data to send to the file encryption-decryption module by the interface proxy module, the file encryption-decryption module is carried out encryption to the data that receive, and again result is returned to terminal equipment by the interface proxy module.
After the intact data that receive of file encryption-decryption resume module, result directly can also be kept in the memory module of storage card, and not return to terminal equipment.In the present embodiment, the data of file encryption-decryption resume module are obtained from terminal equipment, and the file encryption-decryption module can also be obtained data and encrypt or decipher from memory module, and result exported to terminal equipment or are kept in the memory module.Certainly, if desired the data in the memory module are encrypted or deciphered, terminal equipment need obtain the memory address of these data in advance, again memory address is notified to the file encryption-decryption module, then, the file encryption-decryption module is obtained data according to memory address again from memory module, and encrypts or decipher.

If repeatedly use same service module function in the section between terminal equipment needs at a time, can be behind each the startup, for this service module function distributes a dynamic function number, and the dynamic function that distributes number returned to terminal equipment, terminal equipment utilizes dynamic function number to carry out alternately with service module function.Here, for dynamic function number difference, the function of service module function of the present invention number also can be called static function number.In this case, the interface proxy module need be in feature list mapping relations between the static function number of log file encryption and decryption module and the dynamic function number.When the interface proxy module receives message from terminal equipment, from the function field of message, obtain earlier dynamic function number, determine corresponding static function number number from feature list according to this dynamic function again, number call corresponding service module function according to static function then.That is to say that terminal equipment can repeatedly call same service module function simultaneously, and different application datas is independently handled.
Such as: the static function of file encryption-decryption module number is 3, and terminal equipment needs encrypt file 1 and file 2 simultaneously.At this moment, terminal equipment need send that to carry static function for twice number be 3 service function request message to the interface proxy module, i.e. twice encryption request message.In the interface proxy module each time after the startup file encryption and decryption module, can distribute dynamic function number, such as distributing dynamic function numbers 31 and 32, and be recorded in the feature list, as shown in Table 4.Afterwards, terminal equipment can utilize dynamic function numbers 31 and file encryption-decryption module to carry out alternately file 1 being encrypted; Simultaneously, terminal equipment utilizes dynamic function numbers 32 and file encryption-decryption module to carry out alternately file 2 being encrypted, i.e. realization is encrypted file 1 and file 2 simultaneously.
| The service function title | Static function number | Dynamic function number |
| … | … | … |
| File encryption-decryption | 3 | 31 |
| File encryption-decryption | 3 | 32 |
| … | … | … |
Table four
In the mutual process of terminal equipment and service module function, if terminal equipment makes a mistake, need storage card that service function is provided again, terminal equipment can send to the interface proxy module and carries function number and the reseting mark reset request message for " 1 ", the interface proxy module is again to sending reset request message with number corresponding service module function of function, this service module function withdraws from the applicable procedures of self, carries out initialization procedure again, provides the function service for terminal again.
Comprise the count flag that is used to write down self current transmission message number between terminal equipment and the storage card in the interactive messages, after terminal equipment or storage card send message at every turn, if in the default time interval, receive response message, just send next message message, and the value in the count flag in this message is added 1; If do not receive response message, terminal equipment or storage card will resend current message message to the other side, and with the retransmission flag set in the current message message.
