It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, in one embodiment of the present invention, a method for securely managing password information is provided, which is applied to an object interlocking management system, wherein the object interlocking management system includes an object interlocking, an object linkage key, and an object interlocking management platform, and the method includes the following steps:
step S1, the object interlocking management platform acquires the identification information of the object interlocking and identifies the type of the object interlocking based on the identification information of the object interlocking; acquiring identification information of the internet of things key, and identifying the type of the internet of things key based on the identification information of the internet of things key;
step S2, the object interlocking management platform matches a corresponding password segmentation mode in a database based on the type of the object interlocking and the type of an object linkage key;
step S3, the object interlocking management platform generates an unlocking password, and divides the unlocking password based on the password dividing mode to obtain a first sub-password and a second sub-password; the unlocking password, the first subcode and the identification information of the internet of things key are sent to the object interlocking, and the second subcode is sent to the internet of things key; the object interlock is used for storing the first subcode and the identification information of the internet of things key in an associated mode;
step S4, when the object interlocking key is close to the object interlocking to unlock the object interlocking, the object interlocking acquires a second subcode on the object interlocking key and identification information of the object interlocking key; matching the corresponding first sub-passwords according to the identification information of the internet of things key, and combining the matched first sub-passwords with the matched second sub-passwords in a corresponding combination mode to obtain a combined password; and judging whether the combined password is the same as the unlocking password.
In this embodiment, the method is applied to a scheme of separately storing unlocking codes of the object interlocks. Specifically, the object interlocking management system comprises an object interlocking, an object linkage key and an object interlocking management platform, wherein the object interlocking management platform is used for managing the use, authority, password information and the like of the object interlocking and the object linkage key.
As described in step S1, when the password information is configured, the object-interlocking management platform needs to obtain the type of the object-interlocking and the type of the internet-of-things key, and different password processing modes can be adopted when the types of the object-interlocking and the type of the internet-of-things key are different, so as to increase password security. Specifically, the type of the object interlock and the type of the internet of things key can be obtained through identification information of the object interlock and identification information of the internet of things key, and character features in the identification information can express corresponding type information, which is not described herein.

The object interlocking management platform in the step S3 generates an unlocking password, and divides the unlocking password based on the password dividing mode to obtain a first sub-password and a second sub-password; the unlocking password, the first subcode and the identification information of the internet of things key are sent to the object interlocking, and the second subcode is sent to the internet of things key; the object interlock is used for storing the first subcode and the identification information of the internet of things key in an associated mode; generally, an illegal user decodes an internet of things key to acquire a corresponding unlocking password; in this embodiment, the internet of things key does not store all the passwords, but only stores part of the passwords, i.e. the second sub-passwords. While another part of the code, the first subconjugate, is stored in the above-mentioned object lock. In some embodiments, the unlocking password may not be sent to the physical interlocking device, and may be stored in the physical interlocking management platform, and may be invoked when unlocking.
