[description of drawings]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is that the present invention enters the flow chart before upgrading.
Fig. 2 is after the present invention enters renewal, server, terminal remote interaction diagrams.
[embodiment]
The present invention is described further to consult Fig. 1 and Fig. 2.
Described terminal comprises a rate update processing module, is used for setting up the remote interaction agreement with server.Described remote interaction agreement is based on the GSM/GPRS technology.As shown in Figure 1, report server behind the starting up of terminal, can be when reporting with going up the rate version number that host ID and terminal are used at present.The rate version number of server through database management corresponding terminal.When this terminal of discovering server with rate version when being not up-to-date version, server will notify terminal to need remote update rate version.If terminal is confirmed to upgrade, then terminal is carried out update request, enters the upgrading configuration process.Perhaps confirm not upgrade immediately, then write the latest edition rate effective date earlier, wait when starting shooting for the second time behind the terminal closedown and carry out update request more automatically, enter the upgrading configuration process.Simultaneously, server can initiatively issue update request and give terminal as required.
In conjunction with Fig. 2, after if server is initiatively initiated update request (perhaps confirm to upgrade or terminal closedown after start for the second time) as user among Fig. 1, the ready information of the public words upgrading of terminal transmission arrives server, and Server Transport terminal public words file identification sign indicating numbers (CRC) are given terminal then.With regard to transmission course identification code (CRC), and request upgrade file sequence number was given server after terminal received.Server just issues the upgrade file sequence number, and upgrade file is transferred to terminal.If end of file transfer, then process stops, otherwise, just enter circle transmission, promptly jump to terminal transmission process identifier sign indicating number (CRC), and ask the upgrade file sequence number to give this step of server, server continues the transmission upgrade file to terminal.
When the transmission upgrade file, according to the interaction protocol of terminal and server, upgrade file is encrypted, CRC check, escape is handled.The cryptographic algorithm that present embodiment adopts is based on the binary system redundant arithmetic, the combinational algorithm of Chinese remainder theorem algorithm.
The transmission structure of data is:
0x55, the 0xAA presentation protocol is byte end to end.
Only the order PDU (protocol Data Unit) of data is encrypted in transmission course, the corresponding communication random number sign of transmission is arranged in the command header, by random number sign random (encrypted random number) byte stream of ordering PDU is carried out the binary system redundant arithmetic and encrypt, step is as follows:
1. encrypt
Order PDU is { a0 a1 a2 a3...ai} expressly
----＞
Random (encrypted random number)
Order PDU ciphertext { (a0+random) ﹠amp; 0xFF, (a1+random+64) ﹠amp; 0xFF, (a2+random+64*2) ﹠amp; 0xFF, (a3+random+64*3) ﹠amp; 0xFF ..., (ai+random+64* (i%4)) ﹠amp; 0xFF, }
2. integrality effect, by the Chinese remainder theorem of command header unit and order PDU is calculated, the redundancy value that obtains is inserted the order tail unit.
3. the byte stream escape is handled, and realizes transparent transmission.This word byte stream is respectively with 0x55, and the 0xAA presentation protocol is byte end to end, handles so need carry out escape to command header unit, order PDU and the order tail unit of the inside.
Concrete processing is as follows: 0x55--＞0xAB, 0x01
0xAA--＞0xAB，0x02
0xAB--＞0xAB，0x03
In deciphering PDU, do corresponding processing.
Described terminal comprises PSAM card safety encipher module.The unique affirmation and writing in the database when PSAM Ka Kaika of the rate key of server through database management corresponding terminal, this key.After the rate upgrade file successfully downloaded to terminal, terminal used the rate key that obtains to attempt opening PSAM card application area.Have only successfully and just can carry out writing of corresponding rate after the unlatching, newly downloaded rate upgrade file writes backup rate district earlier, replaces after the rate effective date is effective.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process according to this, i.e. the equivalence of doing according to claim of the present invention and description changes and modification, all should still belong in the scope that the present invention contains.
