Detailed Description
The invention is further described with reference to the following drawings and detailed description.
A one-time password verification method of an electronic lock comprises a time module, a password input module and a processor, wherein a one-time password generation module, a one-time password verification module, a locking counting module and a counting module are arranged in the processor, the one-time password verification module controls a driving module, and the method comprises the following steps: A) the one-time password generating module generates a one-time password according to the time information provided by the time module; B) after the processor receives an input password, the locking counting module enables the one-time password generating module to be in a locking state and enters a counting mode; C) the one-time password verification module compares the input password with the password generated by the one-time password generation module, if the input password is successfully compared with the password generated by the one-time password generation module, the step D is executed, and if the comparison is not successful, the step E is executed; D) driving to unlock, and unlocking by the locking counting module; E) the counting module counts the number of unmatched numbers on each digit in the input password and the password generated by the one-time password generating module, and if the counted number value is larger than a preset value, the step G is executed; if the counted number is smaller than the preset value, executing the step F; F) prompting to re-input the password, counting by the locking counting module, comparing a value obtained by counting with a threshold value, executing the step C if the value of the locking counting module is smaller than the threshold value, and executing the step G if the value of the locking counting module is larger than the threshold value; G) and if the unlocking fails, an alarm is given, and the locking counting module unlocks.
The one-time password generation module generates a system key ID by using the time information provided by the time module and the processor, and the specific generation formula is that the system key ID is the current timestamp plus the processor. For example, the time module and the processor form a system key ID of 1234, and then the system key ID and the counter T are used as a dispersion factor to encrypt with DES to generate 8 bytes of ciphertext, where the first 4 bytes are rolling code a, and the last 4 bytes are encrypted ciphertext a, so that the rolling code a is 1234 and the encrypted ciphertext a is 5678.
The processor randomly inserts a random number 5, 5 with a binary number of 0101, the first bit of the binary number is 0, the first two bits are 1, 5, the second bit is 1, so the next two bits are 2, 3, the third bit is 0, the next two bits are 4, 6, so the last two bits are 7, 8, so the 8-bit code is 15234678, plus the random number 5, and the final 9-bit code is 152346785.
Assuming that the binary number of the random number 8, 8 is 1000, the first bit of the binary number is 1, the first two bits are 1, 2, then the second is 0, so the next two bits are 3, 5, then the third bit is 1, then the next two bits are 4, 6, so the last two bits are 7, 8, so the 8-bit password is 12354678, plus the random number 8, and the last 9-bit password is 123546788.
Assuming that the binary number of the random number 3, 8 is 0011, the first bit of the binary number is 0, the first two bits are 1, 5, then the second is 0, so the next two bits are 2, 6, then the third bit is 1, then the next two bits are 3, 4, so the last two bits are 7, 8, so the 8-bit password is 15263478, plus the random number 3, and the last 9-bit password is 152634783.
After the processor receives the password input by the password input module, the locking counting module in the processor firstly locks the one-time password generating module, so that the one-time password generating module cannot generate a new one-time password, and the locking counting module enters a counting mode. When entering the counting mode, the value of the locking counting module is 0, the value of the locking counting module is added with 1 every time the processor receives the password, and the value is compared with the preset value, if the value of the locking counting module is larger than the preset value, the unlocking is failed, and the locking of the one-time password generation module is released.
Inputting a 9-digit password through a password input module, carrying out reverse reasoning on the 9-digit password through a reverse reasoning module to obtain a rolling code B and an encrypted ciphertext B, judging whether the rolling code B is larger than the rolling code A, and if not, executing the step E; if yes, judging whether the encrypted ciphertext B is consistent with the encrypted ciphertext A, if yes, executing the step D, and if not, executing the step E.
And the counting module counts the number of unmatched input passwords and the one-time passwords when the one-time password verification module compares the input passwords with the one-time passwords, compares the counted number with a threshold value, fails to unlock if the counted number is larger than the threshold value, and executes the step F if the counted number is smaller than the threshold value.
The preset value and the threshold value can be set according to the requirements of a user, the preset value and the threshold value are constants of times, and the user can set the numerical value.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
