Under the control of microprogram control unit, finish the system for TV set safeguard protection by described 5 modules effect.Shown in 1 and 2 workflow of the present invention is described in conjunction with the accompanying drawings, at first user's start, system control module judges whether system is provided with secure password, and secure password is not set, and directly enters system; Be provided with secure password, called authentication module and memory module is verified the startup password password by control module; To the television set of secure password is not set, after entering system, the user can be provided with password for the system that secure password is not set as yet by configuration module, the password configuration is called configuration module by control module, the secure password of configuration is newly stored in the memory module, after the configuration successful, system needs login again, with the correctness of the checking new secure password of being imported; The user is if revise or secure password that deletion has been provided with, and system control module at first calls modified module, in this module, must new secure password could be set by old secure password checking; Old secure password checking is correct, and control module is called configuration module and gone to be provided with new secure password, and new secure password is stored in the memory module, and system needs login again; When new secure password is set to null value NULL, finish deletion to old secure password; Security password is revised and is called memory module by control module, and modified module and configuration module are realized.
Its method for security protection is described in detail as follows: after user's start, in system control module, at first read secure password by system control module to memory module, be stored in certain temporary variable, suppose that variable is CRYPTOGRAM; This moment, system control module can judge whether the value of CRYPTOGRAM is empty, if be empty, then expression is not provided with secure password as yet, and system can directly enter normal operating conditions, and the user is TV reception normally; If be not empty, then expression has been provided with secure password;
If this system for TV set has been provided with secure password, then system control module will call authentication module, the user must locate to import effective secure password at password 1 (to dependent variable PASSWOERD1) and password 2 (to dependent variable PASSWOERD2), effectively secure password is meant whether the password of twice input is six bit digital, whether the user password of twice input is consistent, after the user finishes and determines the user password of its input, can judge in authentication module at first whether the input user password is effective, if the user password of user's input is invalid, then system control module can be pointed out the user, and directly finishes; If the user password of input is effective, then authentication module returns the user password of this input to system control module.
Corresponding program module is as follows:
If(((Strtol(PASSWOERD1)＝＝1)&&(Strtol(PASSWOERD2)＝＝1)
\
&&(Strlen(PASSWOERD?1)＝＝6)&&(Strlen(PASSWOERD2)＝＝
6))\
||((PASSWOERD1＝＝NULL)||(PASSWOERD2＝＝NULL)))
{
If(strcmp(PASSWOERD1，PASSWOERD2)＝＝0)
Return (PASSWOERD1); // return effective password
Else
{
PromptUser (" password of twice input is inconsistent "); // prompting user
Return(Fail)；
}
}
Else
PromptUser (" password is necessary for six bit digital or is sky ");
After authentication module returns the user password of effective input to system control module, suppose to be stored in temporary variable Temp, system control module at first reads secure password to memory module, be stored in temporary variable CRYPTOGRAM, judge relatively then whether PASSWOERD1 and CRYPTOGRAM are same character strings; If same character string then successfully enters system; Otherwise,, directly enter holding state by the system control module effect.
Corresponding program module is as follows:
If(Temp！＝Fail)
{
If (strcmp (PASSWOERD1, CRYPTOGRAM)==0) if // two character strings are identical
{
ExitCurrrentView (); // withdraw from the secure password authentication module
EnterSystem (); // enter system
}
Else
{
PromptUser (" password is incorrect "); // prompting user password is not right
ExitCurrrentView()；
EnterStandby (); // enter holding state
}
}
Else
EnterStandby()；
When system is not provided with secure password as yet, the user can be provided with password for the system that secure password is not set as yet by configuration module, at first call configuration module by system control module, the user finishes setting in configuration module, the password configuration calls configuration module by control module and memory module realizes; Its step is as follows: if the user has entered the system for TV set of no secure password, then the user can be provided with secure password for this system by configuration module, the same user password of input in two input frames, if the user password of input is identical, control module is verified the correctness of the user password of input, whether relatively more consistent with secure password with the user password of judging input, if inconsistent, it is invalid that the user password of input is provided with; If consistent, success then is set, the user need use the secure password that has been provided with login system again; If the user selects " cancellation ", then withdraw from the secure password setting.
The user is if revise the secure password be provided with, and system control module at first calls modified module, in this module, must new secure password could be set by old secure password checking; Secure password is revised and is called memory module by control module, and modified module and configuration module are realized.The system security controls module accesses system safety password CRYPTOGRAM by memory module, and the user password PASSWORD with user's input relatively judges then; If the user can't be by old secure password checking, then directly effect of system control module is withdrawed from secure password and is revised; If by old secure password checking, then system control module calls configuration module again and goes to be provided with new secure password, new secure password is stored in the memory module, and system must use new secure password login system again.
Old password authentication program module in the secure password modified module is as follows:
If(((Strtol(PASSWORD)＝＝1)&&Strlen(PASSWORD)＝＝6))\
||(PASSWOERD1＝＝NULL) )
{
If(Strcmp(PASSWORD，CRYPTOGRAM)＝＝0)
ValidatePass (); // old password is correct
Else
ValidateFail (); // old password is incorrect
}
Else
PromptUser (" password is necessary for six bit digital or is sky ");
