Embodiment approach

[0044] see Figure 5 , as an implementation manner, the step S330 may include:

[0045] Step S331, decomposing the second encrypted data into an array containing 16 elements, wherein each element corresponds to one of the 16 bytes of the second encrypted data.

[0046] Step S332, according to the value of each element, look up the corresponding value in the preset password table to obtain 16 hexadecimal numbers.

[0047] It can be understood that the preset password table can be set so that one byte of data corresponds to a 4-bit hexadecimal number, so that 16 hexadecimal numbers can be obtained after looking up the table for 16 elements, and each The length of a hexadecimal number is 4bit.

[0048] Step S333, combining the 16 hexadecimal arrays into a number with a length of 8 bytes, and using the number with a length of 8 bytes as the common password.

[0049] It is understandable that a hexadecimal number corresponds to 4 bits, and these 16 numbers are combined in a pres...

Abstract

The embodiment of the invention provides a dynamic password generating method, a dynamic password authentication method and a device. The method comprises the steps of acquiring the current time, calculating a common password according to a preset rule, acquiring a unique identification code of a user terminal, conducting the encryption calculation on the unique identification code to obtain the password of the user terminal, and encrypting the common password and the password of the user terminal to generate an unlocking password. The generated unlocking password is encrypted for many times, so that the unlocking password is not easy to crack. Therefore, the unlocking password is safer. Only user terminals with the identification codes thereof to be stored in an intelligent door lock in advance can unlock the door lock, so that the operation is more reliable.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to a dynamic password generation method, a dynamic password authentication method and a device. Background technique [0002] The dynamic password generated by the dynamic password generating device is also called one-time password (One-time Password), which means that the user's password is constantly changing dynamically according to time or the number of times of use, and each password is only used once. At present, dynamic passwords are widely used in application fields such as online banking, online games, telecom operators, e-government affairs, and enterprises. However, due to its short length, the dynamic password has a greater security risk. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a dynamic password generation method, a dynamic password authentication method and device, so as to solve ...
