Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
In order to facilitate understanding of the present invention, the embodiment of the present invention is first briefly introduced, in order to improve the security of the shared charger password, the embodiment of the present invention discards the conventional method of password extraction of the fixed password bank, but combines the actual number of the password input keys corresponding to the charging device and the corresponding digital situation, and simultaneously, automatically selects or sets the total password length by a technician, then automatically calculates a plurality of corresponding selectable dynamic codes and randomly selects, and finally combines the dynamic codes, the parameter codes and the check codes to obtain the final authority password, and because the whole process, the dynamic codes are in an actual situation of the charging device and the preset password length, and have randomness, so that the finally obtained dynamic codes have controllable length and very strong randomness, and the check codes are also determined based on the dynamic codes, the preset parameter codes and the key numbers, and the corresponding check codes are also in a situation of having very strong randomness, and are also suitable for the actual situation of the charging device, and finally the dynamic codes, and the parameter codes and the check codes are combined to obtain the final authority password, and the practical situation of the charging device has very high security, and the security of the shared password bank is greatly improved. The details are as follows:
fig. 1 shows a flowchart of an implementation of a method for generating a rights password according to an embodiment of the present invention, which is described in detail below:
s101, obtaining a maximum value m of key numbers corresponding to the charging equipment, a number set corresponding to the keys, a preset password length h and a preset parameter number, wherein m and h are positive integers, each key corresponds to one number in the number set only, and the preset parameter number is a positive integer smaller than or equal to m.
Because of the requirements of different charging devices on the password security level and the limitation of the actual hardware environment and cost, the number of the password input keyboards set by each charging device in practical application also has certain difference, for example, some small mobile phone sharing chargers have smaller volumes and lower cost and relatively lower requirements on the password security level, so that the password keyboards of general mobile phone sharing chargers also have smaller numbers of contained keys, for example, three keys and four keys can be contained, and for the sharing charging piles of electric automobiles, the volume is high, the cost is high, and the requirements on the level of the password security are also high in consideration of the higher security requirements of the used strong electricity, so that the number of keys contained in the password keyboards of general sharing charging piles is also more, for example, 9 keys can be contained, and therefore, for different charging devices, certain difference exists in the number of keys which are specifically contained, and certain difference correspondingly exists in the number conditions and the maximum value conditions of the keys. The number set corresponding to the keys refers to a set formed by numbers corresponding to each password key, if the number set is {1,2,3,4}, when there are 4 cases, the corresponding numbers are 1,2,3, and 4, respectively. The password length refers to the total length of the finally generated password, and in the embodiment of the invention, the finally generated password contains three parts of contents of dynamic code, parameter code and check code, so the password length refers to the total length of the three parts of contents. The parameter numbers are preset, and a technician can classify different charging equipment according to one digit of numbers set by different actual charging equipment, and set corresponding parameter numbers for each type respectively so as to generate corresponding passwords aiming at the actual conditions of different charging equipment.
In practical application, the two-dimensional code recorded with the equipment information of the charging equipment and the server address is preset on the charging equipment, so that when a user accesses the server through the two-dimensional code, the server can identify the equipment and read the data such as the number of keys of the equipment, the password length of the corresponding digital set, the preset parameter number and the like.
S102, combining dynamic codes with the length of h-2 for the numbers in the digital set to obtain m (h-2) dynamic codes, and randomly selecting one dynamic code.
In the embodiment of the invention, the finally generated password comprises three parts of contents of a dynamic code, a parameter code and a check code, wherein the parameter code is preset by a technician, the check code is calculated according to the maximum values of the dynamic code, the parameter code and the key number, the parameter code and the check code are all one-digit numbers, and the dynamic code is generated when the user needs to acquire each time, so that the length=h-2 of the dynamic code.
After determining the length of the dynamic code, the embodiment of the invention randomly selects numbers from the number set to perform ordering combination to obtain corresponding m (h-2) dynamic codes, for example, the number set is assumed to be {1,2,3,4}, the length of the dynamic code is 3, and at this time, the following 64 dynamic codes can be obtained through random ordering combination:
111 112 113 114 211 212 213 214 311 312 313 314 411 412 413 414
121 122 123 124 221 222 223 224 321 322 323 324 421 422 423 424
131 132 133 134 231 232 233 234 331 332 333 334 431 432 433 434
141 142 143 144 241 242 243 244 341 342 343 344 441 442 443 444
and then randomly selecting a dynamic code from the codes.
S103, calculating the digital sum of each number in the selected dynamic code, and calculating the check code based on the digital sum, the preset parameter number and the maximum value m of the key numbers.
After determining the dynamic code, embodiments of the present invention may further calculate the sum of the digits in the dynamic code, for example, assuming that the dynamic code is 123, where a corresponding sum value of 6 may be obtained. After determining the sum, a corresponding check code is calculated based on the sum and the parameter number and the maximum value of the key number, wherein the specific calculation method includes, but is not limited to, performing an and operation on each parameter or performing a process according to the second embodiment of the present invention. Because the dynamic code has very strong randomness, and the maximum values of the parameter number and the key number are closely related to the actual situation of the charging equipment, the finally obtained check code is suitable for the charging equipment while having very strong randomness.
S104, combining the selected dynamic code, the preset parameter code and the check code to obtain a corresponding authority password, and sending the authority password to the charging equipment and the user equipment so that the user can acquire the use authority of the charging equipment based on the authority password received in the user equipment.
After the dynamic code and the check code are calculated, the embodiment of the present invention combines them with the parameter code to obtain the final authority password, wherein the specific combination sequence is not limited herein, for example, if the obtained dynamic code is 123, the parameter code is 3, the check code is 2, and the final authority password can be 12332.
As a specific implementation manner of calculating the check code in the first embodiment of the present invention, as shown in fig. 2, the second embodiment of the present invention includes:
s201, calculating the sum value of the digital sum and the preset parameter number to obtain a first check parameter.
S202, calculating a second checking parameter and a correction coefficient based on the digital set, wherein the second checking parameter is smaller than or equal to m.
S203, performing AND operation on the first check parameter and the second check parameter, and obtaining a sum value of an original check code and a correction coefficient obtained by the AND operation to obtain a corresponding check code.
In the embodiment of the invention, the digital sum of the dynamic code is summed with the parameter code to obtain the corresponding first verification parameter, and the first verification parameter is based on
The sum value of the numbers and the parameter numbers is difficult to know in advance due to randomness, the second check parameter is not larger than m, so that the sum operation result is inevitably smaller than or equal to m, and in order to prevent mismatching of the number sequence on the keyboard and the maximum value m of the keyboard, for example, the number set corresponding to the keyboard is {1,2,3,4}, and the maximum value m=4 of the keyboard, so that the finally obtained sum operation result is not larger than m, but no corresponding number is arranged on the keyboard.
As a specific implementation manner of calculating the second calibration parameter and the correction coefficient in the second embodiment of the present invention, as shown in fig. 3, the third embodiment of the present invention includes:
s301, if the digital set contains the number 0, sets the second verification parameter to m, and sets the correction coefficient to 0.
S302, if the digital set does not contain the number 0, setting the second checking parameter to m-1, and setting the correction coefficient to 1.
Since the original check code obtained by the and operation may have 0, for example, the dynamic code is assumed to be 134, the corresponding digital sum is 8, the second check parameter is 4, at this time, the and operation is performed on 8 and 3 (i.e. 8 is converted into binary number 1000,4 and is converted into binary number 0100), the result is decimal 0, but in practical situations, the keyboard number may not have 0, that is, when the digital set does not contain 0, the check code cannot be input at this time, and the check code is invalid, therefore, the embodiment of the invention sets the second check parameter as m-1 and the correction parameter as 1 for the situation that the digital set does not contain 0, so that the validity of the check code can be ensured even if the original check code appears in the and operation is 0, and since the second check parameter is m-1, the maximum value of the and operation is m-1, so that the value of the final check code cannot overflow the digital set range.
As a fourth embodiment of the present invention, after the generation of the right password by the above-described embodiments one to three is completed, as shown in fig. 4, it includes:
s401, acquiring charging mode information input by a user, and searching corresponding charging time length based on the charging mode information, wherein the charging time length is used for controlling the authority opening time length of the charging equipment.
The charging mode refers to a charging package selected by a user for payment, and mainly refers to the time duration of charging selected by the user.
Transmitting the permission password to the charging device and the user device, comprising:
s403, sending the permission password to the user equipment, and sending the permission password and the charging time length to the charging equipment, so that the charging equipment starts charging timing when the charging permission is opened, and closing the charging permission when the charging timing time length is equal to the charging time length.
After the permission password and the charging time are acquired, the embodiment of the invention can send the permission password to the charging equipment together, and simultaneously can send the permission password to the user equipment independently, so that the user can acquire the permission password and charge the user.
In the embodiment of the invention, the actual number of keys and the corresponding number condition of the key are input by combining the corresponding password of the charging equipment, the total password length is automatically selected or set by a technician, then a plurality of corresponding selectable dynamic codes are automatically calculated and randomly selected, the corresponding check codes are set based on the dynamic codes and the preset parameter numbers and the maximum value of the key numbers, and finally the dynamic codes, the parameter numbers and the check codes are combined to obtain the final authority password.
