Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
The present invention is provided with two coupling counters that constitute based on counter in SIM card, be respectively total counter and detection counter, and a timer; Wherein total counter is used for the number of times that the instruction of operation GSM algorithm authenticates under the recording exceptional situation, promptly write down detection times and surpass the number of times that the instruction of operation GSM algorithm authenticates under the situation of threshold value, in the life cycle of SIM card, total counter only increases counting, does not reset; Detection counter then is used to the detection times that the instruction of operation GSM algorithm authenticates in the unit's of record fixed length time; Timer is used for determining the unit fixed length time.
The embodiments of the invention that provide as Fig. 1, safety certification threshold value that at first need the number of times that operation GSM algorithm authenticates in the unit's of being arranged on fixed length time.For detection counter, comprise the first threshold and second threshold value; In the present embodiment, first threshold is set to 50, the second threshold values and is set to 100.If portable terminal sends the request of authenticated user identity, i.e. request is the instruction of operation GSM algorithm, and then control total is counted the overflow indicator of device, determines whether total counter overflows.The initial value of total counter is 0, overflow value is 5000, overflow indicator is that the number of attempt of Unblock CHV2 is 1, Unblock CHV2 is meant the Personal Unlocking Key PUK2 (PIN2 Unblocking Key) of personal identification code PIN2 (Persona1 Identification Number2), if continuous 3 input errors of user, then personal identification code PIN2 can be lockable, and needs to use the PUK2 release, and the initial value setting of the number of attempt of Unblock CHV2 is made as 10 according to the regulation of GSM11.11 standard.If total counter overflows, then do not carry out authentication and calculate, return the status word " 98 04 " of " condition does not satisfy ".
If total counter does not overflow, then the value with detection counter adds 1.As mentioned above, detection counter is the number of times that is used to operation GSM algorithm instruction in the unit's of record fixed length time, and the unit fixed length time is determined by timer, and in the present embodiment, setting the unit fixed length time is 1 hour.Therefore after per 1 hour finishes, detection counter be resumed into 0,1 hour timer of initial value be relative timing, if timer cycle occurs unusual, i.e. SIM card power down before timer overflows also can not influence the counting of detection counter, if also can not influence the numerical value of detection counter.When authentication is carried out in the instruction that receives an operation GSM algorithm whenever SIM card, the value of detection counter is added 1.
Currency and first threshold 50 with detection counter compares then, if less than 50, represents that then this authentication is in normal condition, normally moves the instruction of GSM algorithm.
If whether the value of detection counter, then further judges this value greater than first threshold 50 less than second threshold value 100,, then export an error result in the instruction of the per twice operation GSM algorithm of SIM card if less than 100.For normal users, general authentication number of times hourly can be less than 50 times, but consider that in particular cases user's authentication number of times hourly may be above 50 times, user frequent situation about moving between 2 lane place for example, therefore in the output error result, the value of total counter is added 1.Do not calculate if the value of detection counter, is not then carried out authentication greater than 100, return the status word " 98 04 " of " condition does not satisfy ".
When the value of detection counter during greater than first threshold 50, whether the value that can also further judge detection counter has all surpassed first threshold 50 in continuous two unit fixed length times, whether the value of promptly judging detection counter had also surpassed first threshold 50 in the last unit fixed length time, if then the number of attempt with current Unblock CHV2 subtracts 1.Whether the number of attempt of judging Unblock CHV2 then equals 1, if equal 1, shows that then total counter overflows, and returns " condition does not satisfy " status word " 98 04 ".If the number of attempt of Unblock CHV2 is not equal to 1, promptly, judge further then whether the value of detection counter surpasses second threshold value 100, if do not surpass 100 greater than 1, error result of output in the instruction of the per twice operation GSM algorithm of SIM card then adds 1 with the value of total counter; If surpass 100, then the value with total counter adds 1, and whether the currency of judging total counter then is greater than overflow value 5000, if not greater than 5000, illustrate also not reach the pintle hook lock number of times, pseudo-result is returned in the then operation algorithm of execution error instruction.If greater than 5000, illustrate to reach overflow value that promptly reached the pintle hook lock number of times, then the number of attempt with Unblock CHV2 is changed to 1, the service conditions of moving the algorithm instruction is not made as satisfies, and return " condition does not satisfy " status word " 98 04 ".
Because total counter and detection counter all are arranged among the EEPROM of SIM card, so when SIM card powers on or reset, can not reset to above-mentioned two counters.
The present invention also creates the binary file that special use is arranged under the GSM subdirectory in SIM card, is used for the identification to WLAN, GPRS bimodulus network interface card SIM card.The bimodulus network interface card is meant and can either inserts GPRS network, can insert the network interface card of wlan network again, and SIM card is to be built in the bimodulus network interface card, is used for the checking to user identity.The bimodulus network interface card can be used to the identification document in the reading SIM card, if the coding of this document existence and file meets the coding in the related specifications, then the bimodulus network interface card starts the authentication that SIM card is carried out the user, otherwise the bimodulus network interface card stops user's SIM card authentication flow process.
On hardware configuration, SIM card of the present invention is identical with common SIM card, difference is to have increased some inner special files on the software of SIM card, owing to content is kept among the EEPROM of SIM card, so the influence that its value is not resetted, powers on.The COS of SIM card of the present invention (Chip Operation System) has enabled the time timer in the chip for common SIM card COS, after the record of timer in the card is reach one hour, automatic value zero clearing with detection counter, in the processing of operation GSM instruction, some functions have also been increased, at first whether Rule of judgment satisfies before carrying out instruction process, changes corresponding sub-processing module over to according to different situations then.
Fig. 2 has provided the workflow diagram of timer of the present invention.The initial value of timer in the SIM card at first is set, and the fixed length of the present invention's timer is set to 1 hour.Judge then whether timer has produced interruption, after timer is started working, every timer digit duration that reaches just triggers once interruption, certainly when SIM card has the I/O data, also may trigger interruption, be the different interrupt requests of two classes but this interruption triggers interruption with the counting of timer.SIM card is distinguished by different interrupt numbers, carries out different processing then.Interrupt if produce, then the timer count value in the SIM card is added 1, judge again whether the timer in the SIM card arrives 1 hour,,,, then continue to wait for interrupt requests if do not arrive 1 hour then with the detection counter zero clearing if by 1 hour.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and do not break away from any modification or partial replacement of the spirit and scope of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
