As shown in fig. 2, in an embodiment of the present invention, a method for generating a control password is provided, which includes:
in step S101, the cryptographic server generates a time to detach from the network connection.
In this step, if the cryptographic server 10 detects that the electronic devices 21, 22, 23, and 24 are disconnected from the network, the cryptographic server 10 generates a time for the electronic devices 21, 22, 23, and 24 to be disconnected from the network.
The password server 10 may generate the networking status of the electronic device in real time by reading the networking status or the network connection parameter of the electronic device at the server side. Alternatively, when the electronic device is disconnected from the network, other network monitoring devices may send signals and related parameters to the server to prompt the password server 10 to generate the network disconnection information of the electronic device.
The time of the disconnection from the network can be acquired by the GPS which is arranged at the server end and the electronic equipment end at the same time when the network is disconnected.
The electronic equipment can be any one of a code case, a delivery box, an electronic room lock and the like, and can generate mechanical or electric control actions through remote control.
Step S102, the password server generates a control password.
In this step, the password server 10 generates a control password by using a password generation algorithm based on the identification codes of the electronic devices 21, 22, 23, and 24 and the time of disconnection from the network.
Therefore, the method for generating the control password in the invention takes the random parameter of the time of the electronic equipment which is disconnected from the network connection as the main variable to generate the control password, thereby improving the security and the reliability of encryption.
In some alternative embodiments, the password server generates the control password using the following password generation algorithm based on the identification code of the electronic device and the time of the network disconnection.
And generating a time random number Seed T _ Seed according to the time of the network connection disconnection. And generating an identification code random number Seed ID _ Seed according to the identification code. And generating a plurality of intermediate random numbers by using the password generation algorithm according to the time random number Seed T _ Seed and the identification code random number Seed ID _ Seed.

generating an intermediate random number I according to the following formula1：
I1＝(A*T_Seed+B*ID_Seed)mod(2^31)
In one example, A, B takes values from the twin prime number pair, and T Seed is a time random number Seed. The ID _ Seed is an identification code random number Seed. Thereby improving the encryption of the password. A. B preferably takes on a prime number of five or more digits. Preferably a and/or B65539.
The preferred values 65539 mentioned above are 861 for one of the twin biomass numbers (65537, 65539), the 5 th fermat number. Wherein A, B takes on values other than the other numbers in the twin prime numbers. And can be further obtained by calculation of an algorithm formula. A. B may be the same value or different values, and when A, B is different values, the above-mentioned value method may be referred to.
In some optional embodiments, generating the control code from the plurality of intermediate random numbers comprises:
according to a plurality of intermediate random numbers I1A first set of multi-bit decimal numbers is generated. For example: generation from multiple intermediate random numbersThe first set of 4, 6 decimal numbers.
The second set of multi-digit decimal numbers is generated according to a control protocol of the electronic device, which is determined according to the number of the electronic devices and the number of the switch states.
For example: the number of bits of the recognizable binary number is determined according to the number of the electronic devices. And identifying the number of the electronic equipment according to the determined binary number of the multiple bits. The electronic device number represented by a binary number is taken as the first part of the character string.
And obtaining the number of bits capable of identifying binary numbers according to the number of the switch states of the electronic equipment. And identifying the switch state number according to the determined digit. The switch state number represented by a binary number is taken as the second part of the character string.
And connecting the first part and the second part to obtain the corresponding multi-digit decimal number. The multi-digit decimal may be 2-4. The specific digit is determined according to the number of the electronic equipment at the user end.
Taking a two-digit decimal number as an example, the description is as follows:
for example, the electronic device has 6 locks, the password is sent to the client on the vehicle, and the user inputs the password on the client to control the on-off of the 6 electronic locks on the vehicle. Due to the binary length of 7 bits for two decimal numbers. The first 4 bits indicate which lock and the last three bits indicate the switch.
For example: 0001-first lock, 0010-second lock. The last three bits 001 are switch 010 off. Specifically, it can be expressed as: 0001010 decimal 10, the first lock, close action.
And respectively inserting each digit in the second set of decimal numbers into the set position of the first set of decimal numbers to generate a plurality of control passwords. For example, each digit of the 2-4 decimal numbers is inserted between the first set of multi-digit decimal numbers.
For example, the first set of multi-bit decimal numbers is a 4-bit decimal number, such as 1234. The second set of 2-bit 10-ary digits generated by the above method is "89", where 1 bit "8" is inserted into the 2 nd bit and another bit "9" is inserted into the 5 th bit, resulting in a 6-bit password 182349. Therefore, the generation of the password is more convenient and reliable.
In some alternative embodiments, the first set of multi-bit decimal numbers is 4-6 decimal numbers and the second set of multi-bit decimal numbers is 2-4 decimal numbers. Therefore, the method reduces the calculation amount while ensuring the encryption and is easier to realize.
And respectively generating random number seeds by the time of breaking away from network connection and the identification codes, and finally generating intermediate random numbers. Thereby improving the randomness, the encryption and the reliability in the password generation process. The encryption reliability is further improved by the combination of two groups of decimal numbers.
As shown in fig. 3, in an embodiment of the present invention, an unlocking method using a control password is provided, and the control password may be generated by the method for generating the control password in the above-described embodiment of the present invention. The electronic device is configured with an identification code, a control code, and a password generation algorithm. The unlocking method of the control password comprises the following steps:

And if the controlled electronic equipment detects that the controlled electronic equipment is disconnected from the network connection with the password server, generating the time for the controlled terminal to be disconnected from the network connection. And the controlled electronic equipment generates a verification password by using a password generation algorithm according to the local identification code and the time when the controlled terminal is disconnected from the network connection. The password generation algorithm may be the same as the password generation algorithm set in the password server or may be a corresponding algorithm, so that a password that can be recognized by the controlled electronic device can be generated. The time of the controlled end getting out of the network connection and the time of the password server end getting out of the network connection are the same time.
The time of the controlled end being disconnected from the network connection is acquired by time-receiving equipment such as GPS equipment arranged at the server end and the client end. The time of the user terminal device and the server terminal must be consistent, and GPS time is used.
And step S202, the user terminal unlocks the controlled electronic equipment according to the control password.
The user terminal receives the control password from the password server. The user terminal inputs the control password into the electronic device. The electronic equipment verifies the verification password through the control password, and if the verification passes, the control code is called to unlock the electronic equipment.
The user terminal refers to a terminal device equipped by a user operating the controlled electronic device. The user receives the control password from the password server through the user terminal. The user inputs the control password into the controlled electronic device.
In some optional embodiments, the electronic device verifying the verification password by the control password comprises: acquiring unlocking time of a user terminal for inputting a control password into electronic equipment; and obtaining the failure time according to the unlocking time and the time when the controlled end is disconnected from the network connection. And if the failure time is within the set time, the electronic equipment verifies the password by controlling the password.
For example, the aging time of the password server and the client is agreed. If the unlocking time is the time difference value obtained by comparing the current input time with the time when the controlled terminal is disconnected from the network connection, namely the failure time, if the failure time is within the preset time, and if the failure time is within 15 minutes, the electronic equipment verifies the password by controlling the password.
Meanwhile, when the password is generated at the password server, the failure time is carried by a set protocol bit or a character string, and after the client receives the password carrying the failure time, the password in the received protocol is decrypted according to the protocol synchronous with the password server, so that the comparison of the failure time is realized.
Therefore, the unlocking method for controlling the password can generate the password at the encryption end and the decryption end simultaneously, and effectively solves the problem that the user terminal cannot use the controlled electronic equipment under the condition of network disconnection. Meanwhile, the generation of the passwords of the encryption end and the decryption end has strong randomness and high reliability.
In some optional embodiments, the plurality of electronic devices comprises: entrance guard terminal, electronic lock, commodity circulation lock or automatic control robot. Thus, the present invention can be used in a variety of applications.
In another embodiment of the present invention, the present invention provides a method, a system, and a device for generating a control password of an electronic device (e.g., an electronic lock), so as to compensate for a situation that a controlled electronic device is operated by a password when a network is disconnected, and also be applicable to a scenario where a large number of controlled devices need to be controlled and managed by a security outage, such as hotel entrance guard, logistics electronic lock, and the like.
The password generated by the invention is seeded by the ID and the timestamp of the electronic equipment, has the characteristics of high safety, carrying of a plurality of control instructions, settable instruction timeliness and the like, and comprises the following steps: and the password server generates an identification code of the controlled electronic equipment.

And the password server generates a control password according to the identification code and the network disconnection time length. And the controlled electronic equipment end user generates a control password and inputs the control password in a time-efficiency range. The controlled electronic device decodes the control password based on the device identification code and the current timestamp. The controlled electronic equipment extracts the control code and interprets and executes the control code.
The algorithm for generating the password comprises the following steps:
1.1, generating equation 1
I ═ (a × T _ Seed + B × ID _ Seed) mod (2^31) formula 1
Wherein a ═ B ═ 65539. T _ Seed is a time random number Seed, ID _ Seed is an ID random number Seed, and I is less than 2^ 31.
