As shown in Figure 1, the present invention, promptly a kind of cipher safe protecting method that prevents that intelligent device input cipher is decrypted comprises the following steps:
1) the intelligent apparatus encryption system is carried out power-up initializing, give initial value, the initial value of time number register of makeing mistakes is made as 1, and timer was made as 0 second by backward timing initial value, that is: be 60 seconds as demarcation, then 60,59,58 ... ..2,1,0 second;
2) judge that whether setting-up time is by 0 second: if the time less than, wait Hou Yiduan to forbid inputing the time of password (do not accept input password), continue to judge whether this setting-up time arrives; If setting-up time arrives, then enter next input password step;
3) input password;
4) password to input carries out computing and comparison, and whether check conforms to: if conform to, then enter the first cryptosecurity control program; If do not conform to, then enter the second cryptosecurity control program;
The first cryptosecurity control program comprises the following steps:
41a) when the input password was consistent with proper password, the number of times of makeing mistakes subtracted 1 counting, and will subtract the count results assignment in time number register of makeing mistakes;
41b) judge whether the number of times register of makeing mistakes overflows is 0: if not, then be back to step 3) and need continue to input and think correct password; If, then the intelligent apparatus encryption system is reinitialized, give initial value, the initial value of time number register of promptly makeing mistakes is made as 1, and timer was made as 0 second by backward timing initial value, finished this cryptosecurity control program, the access system;
The second cryptosecurity control program comprises the following steps:
42a) when input password and proper password were inconsistent, the number of times of makeing mistakes added 1 counting, and will add the count results assignment in the inferior number register of makeing mistakes;
42b) when password does not conform to, also judge whether to withdraw from: if give 60 seconds time values to timer, the time of forbidding inputing password Deng Hou Yiduan, prevent that the cracker from importing continuously, make that the cracker can only the limited number of times of tentative calculation in the limited time, be back to step 2); If not, enter step 42c);
42c) check makes mistakes number of times whether greater than 3 (make mistakes number of times can thinking legal incomer below 3 times): if not, directly be back to step 3) and continue the input password; If enter step 42d);
42d) further check makes mistakes number of times whether greater than 10 (number of times of makeing mistakes can regarded as the cracker more than 10 times):
If not, then lure into to enter wrong road, it is provided with higher entry threshold, 2 multiple value of time numerical value that is about to make mistakes are given time number register of makeing mistakes, and are back to step 3) and continue the input password;
If, report to the police, lure into simultaneously and enter wrong road, 2 multiple value of time numerical value of being about to make mistakes are given time number register of makeing mistakes, be back to step 3) and continue the input password, can then the intelligent apparatus encryption system be reinitialized by the system manager with ann reset for reporting to the police in addition, give initial value, enter step 2) carry out the judgement whether setting-up time has arrived.
To sum up, the present invention adopts the number of times of makeing mistakes to subtract counting and the number of times of makeing mistakes to add counting and carry out cryptosecurity control, and when the input password was not once success, the importer must repeat to input correct password, the number of times that repeats equals the number of times of input error, surpasses 3 times and will input correct password at double.The number of times of makeing mistakes subtracts counting can also be consistent with proper password just when certain password input, the number of times of makeing mistakes subtracts counting, and to overflow be 0 o'clock, it will subtract 1 and become 99....99 (or the FF...FF of 16 systems or binary one 1...11), stops the forcible entry system.Simultaneously, the present invention provides a chance of re-entering during for the accidental input error of legal incomer.If but the cracker wants to import once more necessary wait 60 seconds.If password is 6, the probability of success of then importing 625 days continuously is 1 time (if the words of not reporting to the police), and be to enter system, because made mistakes N time before this, this password must be repeated to input again and just system can be entered N time, and for the cracker, Shu Ru password all is once conjecture each time.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or variation, therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
