Description of drawings
Be described in more detail the present invention below with reference to accompanying drawing, accompanying drawing illustrates the flow chart of the preferred embodiment of the present invention.
Realize best mode of the present invention
System with electronic method transmission PIN code shown in the drawings comprises: security server 3 is used for receiving unique information 1 (representing with the form of filling in personal data) with identifying code 2 forms; And encryption device 4, this device calculates electronic signature 5 according to identifying code 2 subsequently in server.Server 3 is communicated by letter with so-called aerial platform 6 (OTA), and the latter communicates by letter with the SMS service center 8 (SMSC) that is used for from platform 6 receiving encryption keys 7.SMS service center 8 links to each other with SIM card 10, and SIM card 10 is communicated by letter with the mobile GSM mobile handset 12 of the display unit of display 14 forms with comprising keyboard 13, and described service center can send to SIM card 10 with the SMS message of finishing.SIM card 10 comprises: memory 11 is used for storage encryption SMS message 9; Encryption device 16 is used for the user is encrypted by the data 15 of keyboard 13 inputs of terminal 12; And comparison means 17, link to each other with keyboard 13 with memory 11, be used for the data of storage and the data of input are compared.Comparison means 17 also links to each other with the device 18 that is used for PIN code is presented on the display 14 of terminal 12.
When using this system, the user sends to security server 3 with unique information 1 with the form of identifying code 2.Identifying code 2 utilizes encryption device 4 to produce electronic signature 5 in server 3 as input signal.By aerial platform 6, electronic signature 5 is sent to the SMS service center 8 of management SIM card, described service center 8 will sign electronically and 5 be converted to the SMS message 9 that is suitable for sending to the described SIM card 10 that links to each other with cell phone 12.SIM card 10 comprises and is used to receive and the memory 11 of storage encryption SMS message 9.Comparison means 17 will be encrypted the 9 interior electronic signatures 5 of SMS message and compare with the electronic signature 20 that is produced by encryption device 16, and described electronic signature 20 is to produce according to the data of importing by the keyboard of terminal 12.5 is consistent with the electronic signature 20 of user's input if sign electronically, and then comparison means 17 sends to guiding device 18 with a signal, indicates PIN code 19 is shown on the display 14 of cell phone 12, thereby PIN code is sent to the user.
In according to a preferred embodiment of the present invention, terminal 12 is the cell phones such as cellular telephone.Need SIM card (subscriber identification module) to move and be suitable for by having the cell phone of GSM network service now.The private code that in use contains the relevant cell phone of identification GSM network as the SIM card of a cell phone electronic circuit part.This identifying can make the GSM network determine for example position of portable terminal, so that send mobile phone at special time by best launching tower in the network.
Server 3 comprises: the software (not shown) is used to produce PIN code; Three grades of data encryption standards (DES) cryptographic algorithm (Ref. No. 4); The encrypting database (not shown) contains the encryption key of all SIM card of registering and about the link information between a plurality of cell phones and a plurality of relevant SIM card in system.Three grades of DES algorithms are considered to especially to three grades of safer ciphering process of unauthorized decryption.
The SIM card of receiving identifying code there and having verified this user from new user at security server 3 is number in this system effectively the time, and server 3 preferentially utilizes three grades of DES algorithms 4 to produce electronic signature 5 in conjunction with two at least 56 keys that belong to user's SIM card number.Electronic signature 58 SMS of GSM (short-message system) message as unique formatization are sent to user's SIM card 10.These SMS message are encoded, so that the electronic signature 5 of identifying code 2 can be stored into the memory 11 of SIM card 10, and when user's SIM card 10 is received SMS message 9, notify the user to be ready to the PIN code that is produced.
Program in the user moves SIM card 10 subsequently is when sending PIN code, and this program ask the user to import identifying codes 15 by the keyboard 13 of terminal 12 on terminal display 14.In order to produce another electronic signature 20, utilize the encryption device 16 in the SIM card 10, employed according to the encryption device in the security server 3 when identifying code 2 is delivered to security server 34 with a kind of cryptographic algorithm, identifying code 15 is encoded.Then, the comparison means 17 in the SIM card 10 will be stored in the memory 11, compare based on the electronic signature 5 of identifying code 2 and the electronic signature 20 that is produced by encryption device 16.If two signatures are consistent, then comparison means 17 will point out that the signal that PIN code 19 will be shown on the display 14 of terminal 12 sends to control device 18.If these two signatures are inconsistent, then on display, notify user's identifying code 15 not to be accepted, and require to re-enter identifying code 15.If identifying code 15 is still incorrect after trying to import twice again, then stop this program, and do not send PIN code 19, obtain new identifying code 2 up to the user from security server 3, described code can be identical with initial reference code 2, also can be different.
In order to ensure the PIN code that correctly reads transmission, provide the process that confirms the PIN code that sends to the user.The user is presented at PIN code on the display 14 by keyboard input, can realize this validation process, after this, notifies the user whether correctly to import PIN code.If negate, then on display 14, import PIN code of demonstration again, and can repeat this validation process.
In another embodiment,, can in SIM card, provide PIN code, so just not need to have sent PIN code when SIM card provides unique identifier.This is considered to a kind of safer embodiment that can be avoided unauthorized decryption PIN code during sending PIN code.
The present invention is not limited to above preferred embodiment, and can carry out various changes in the case without departing from the scope of the present invention.
