The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
In the method, the system and the storage medium for managing the authorization of the shield machine, the machine code corresponding to the industrial personal computer of the shield machine is generated by the machine code generation module according to the CPU hardware serial number of the industrial personal computer of the shield machine, then the password generated according to the machine code is obtained by the decryption module, the password is decrypted, the starting time and the longest available days are obtained, the timing counting module counts down according to the starting time and the longest available days, when the count down is smaller than a time threshold value, the warning module is reminded to prompt, and when the count down is zero, the screen of the industrial personal computer is locked by the screen locking module.

Meanwhile, the machine codes corresponding to the industrial personal computer one to one are generated, so that the same authorization can not be used in series, the authorization effect is improved, and the shield machine property right party can effectively, conveniently and safely manage the authorization of the shield machine.
The following describes a method and a system for managing authorization of a shield machine according to an embodiment of the present application with reference to the accompanying drawings.
Example one
Fig. 1 is a schematic structural diagram of a shield machine authorization management system according to an embodiment of the present application, and as shown in fig. 1, the shield machine authorization management system may include:
the machine code generating module 101 is used for generating a machine code corresponding to the shield machine control machine according to a CPU hardware serial number of the shield machine control machine;
the decryption module 102 is configured to obtain a password generated according to the machine code, and decrypt the password to obtain a start time and the longest available days;
the timing counting module 103 is used for counting down according to the starting time and the longest available days;
a reminding and warning module 104, configured to prompt when the countdown is less than the time threshold;
and the screen locking module 105 is used for locking the screen of the industrial personal computer when the countdown is zero.
It should be noted that the machine code generation module is further configured to:
acquiring a CPU hardware serial number of a shield tunneling machine control machine;
performing MD5_32BIT calculation on the CPU hardware serial number;
and performing CRC32 calculation on the calculation result to obtain the machine code of the shield machine control machine.
In addition, in the embodiment of the disclosure, the length of the machine code of the shield machine controller obtained by the machine code generation module is a 16-system character string with 8 bits, and the machine code generated by each shield machine controller is unique, so that the machine codes generated by different shield machine controllers are different. Meanwhile, after the machine code generating module generates the machine code, the generated machine code is stored in the shield machine authorization management system so as to be directly read out in the subsequent use without regeneration.
Further, in embodiments of the present disclosure, the password generated from the machine code is server-side generated. Specifically, a 58-bit binary code is mixed with the machine code and then encrypted to generate a 10-bit character string containing only large letters and numbers. Among the embodiments of the present disclosure, the 58-bit binary code includes a dongle check bit, a machine code check bit, a start time, and the maximum available days.
Specifically, in the embodiment of the present disclosure, 1 to 6 bits of the 58-bit binary code are dongle check bits, 7 to 12 bits are machine code check bits, 13 to 30 bits are start time, 31 to 44 bits are the longest available days, and then 4 th, 8 th, 12 th, 16 th, 20 th, 24 th, 28 th, 32 th, 36 th, 40 th, 44 th, 48 th, 52 th, 56 th bits (4 times of digits) of the 58 bits are set as meaningless random bits on the basis of the existing 44 bits. After the decryption module decrypts, the set random bit is removed, then the random bit is verified with the machine code and the dongle data of the shield machine industrial personal computer, and the shield machine industrial personal computer can be authorized to use after the verification is successful, and the authorization time limit is counted down.
In an embodiment of the present disclosure, the start time in the 58-bit binary code is 18 bits of the current year, month and day when the server generates the password. For example, if the time for the server to generate the password is 2019, 10/1, 20191001-. And in the embodiment of the present disclosure, the available days in the 58-bit binary code are 31-44 bits that are obtained by converting the available days into 2-bit left-end complementary 0 and placing 14 bits into the 58-bit binary code.
Further, in the embodiment of the disclosure, the decryption module verifies the decrypted data with the machine code and the dongle data of the shield machine tool. Specifically, the decryption module obtains the value of the dongle data storage area from the dongle identification module, and then performs 32-bit decryption on the obtained value to convert the value into a binary system with a length of 20 bits, which is called a dogid for short. Comparing the 1-3 bits after the random bits are removed after decryption with the 3 bits before the dogid, comparing the 4-6 bits with the 17-19 bits of the dogid, and checking the machine code if the comparison is successful. Otherwise, the user directly prompts that the password input is wrong and the authorization fails.
Further, in the embodiment of the present disclosure, the decryption module converts the 16-ary machine code in the storage area into binary, called cid for short. And then comparing the 7-9 bits after the random bits are removed after decryption with the first 3 bits of the cid, comparing the 10-12 bits with the last 3 bits of the cid, and if the comparison is successful, authorizing the successful shield machine to start using. Otherwise, the user directly prompts that the password input is wrong and the authorization fails.
Further, in the embodiment of the disclosure, after the authorization is successful, the timing counting module may count down according to the start time and the maximum available days in the password, so as to effectively prevent the user from prolonging the authorization time by modifying the local time of the industrial personal computer.
Specifically, in the embodiment of the disclosure, if the start time is authorized successfully on the same day, the timing counting module converts the available days into minutes, counts down, and performs a subtraction operation of 1 per minute when the shield tunneling machine authorization management system operates every minute. If the user is not authorized on the same day at the starting time, the timing counting module calculates the difference between the time of the current password input and the starting time in the decryption module, subtracts the difference from the available days to obtain the final available days, and converts the final available days into minutes for countdown.
For example, assume that the authorization start time for acquisition is 20191021 and the available days are 30 days. Then if the user successfully authorizes the current day on day 21/10/2019, the time count module starts to count down from 30x24x 60-43200 minutes. If the user successfully authorizes the current day on day 23/10/2019, the time count module starts to count down from 40320 minutes (30- (23-21)) x24x 60.
In the embodiment of the disclosure, when the countdown is less than the time threshold, the reminding and warning module prompts. Optionally, the reminder alert module may prompt that the authorization is about to expire when the remaining time of the countdown of the time counting module is less than 100 hours. Alternatively, the reminder alert module may prompt that the authorization is about to expire when the remaining time of the countdown of the time counting module is less than 10 days.
And in the embodiment of the disclosure, when the countdown is zero, the screen locking module locks the screen of the industrial personal computer. In addition, under the state of screen locking, information security management is added, so that a user is prevented from cracking the shield machine authorization management system under the state of screen locking, and the use of the industrial personal computer is prolonged. Specifically, in the embodiment of the present disclosure, a hook keyboard may be added to the application layer keyboard hook; shielding three hot keys of alt + f4, ctrl + esc and win + tab; modifying the registry and shielding the task manager; the background finishes the desktop process and restores after unlocking; and reserving a shutdown operation entrance.
In some embodiments, the screen lock module is further configured to provide a password entry box and an unlock button. And the screen locking module is further used for:
step 1, acquiring an input unlocking password;
step 2, verifying the unlocking password;
and 3, when the verification is passed, unlocking the screen based on the unlocking password.
In the embodiment of the present disclosure, the verification method for the unlocking password may refer to the verification method for the decryption module, which is not described herein again.
In some embodiments, the screen lock module may also obtain an entered provisional password. Wherein, if the bits 31-36 are the same as the bits 25-30 in the 58-bit binary system after the temporary password is decrypted, the temporary password passes the verification. When the provisional password is verified, the screen may be unlocked for 24 hours.
In some embodiments, the screen lock module may also obtain an entered passkey. And if the bits 37-42 are the same as the bits 25-30 in the 58-bit binary system after the temporary password is decrypted, the universal password passes the verification. If the universal password passes the verification, the screen can be unlocked for 24 hours.
In summary, the shield machine authorization management system provided by the application generates the machine code corresponding to the shield machine control machine industrial personal computer according to the CPU hardware serial number of the shield machine control machine through the machine code generation module, then obtains the password generated according to the machine code through the decryption module, decrypts the password to obtain the start time and the longest available days, the timing counting module counts down according to the start time and the longest available days, when the count down is smaller than the time threshold, the warning module is reminded to prompt, and when the count down is zero, the screen of the industrial personal computer is locked by the screen locking module. Therefore, the shield machine authorization management system can help the property right party to rule the behavior that the leasing party violates the leasing contract to use the shield machine, so that the labor cost and the maintenance cost in the shield machine management are reduced. Meanwhile, the machine codes corresponding to the industrial personal computer one to one are generated, so that the same authorization can not be used in series, the authorization effect is improved, and the shield machine property right party can effectively, conveniently and safely manage the authorization of the shield machine.
