Embodiment 1

[0100]This embodiment 1 is executed on the premise of receiving the above-mentioned query instruction. As an embodiment, the aforementioned query instruction is generally issued under the premise that the Internet of Things device is online.

[0101]Before describing the first embodiment, the storage of the target password as the device password of the Internet of Things device in the above step 103 is described:

[0102]In one example, in order to improve the storage security of the device password, the device password of the Internet of Things device is often encrypted before the device password of the Internet of Things device is stored. Based on this, storing the target password as the device password of the IoT device in the above step 103 may include: encrypting the device password of the IoT device according to the generated password encryption key to obtain the first encrypted ciphertext, and encrypting the first encrypted ciphertext. The ciphertext is stored in the designated sto...

Embodiment 2

[0116]The example 1 is described above. The following describes Embodiment 2:

[0117]Example 2:

[0118]The second embodiment is executed on the premise of detecting the aforementioned export instruction. As an embodiment, the export instruction is generally issued under the premise that the IoT device is offline.

[0119]Applied to this embodiment 2, in order to improve the storage security of the device password, the device password of the Internet of Things device is often encrypted before the device password of the Internet of Things device is stored. Based on this, storing the target password as the device password of the IoT device in the above step 103 may include: encrypting the device password of the IoT device according to the generated password encryption key to obtain the first encrypted ciphertext, and encrypting the first encrypted ciphertext. The ciphertext is stored in the designated storage medium. Here, the designated storage medium may be a database or the like, which is ...

Abstract

The application provides a password management method and device. In this application, by generating a random number and converting the random number into a target password that meets the requirements of the preset password rules, the target password is stored as the device password of the IoT device, so as to realize random and dynamic generation of the device password of the IoT device, and The password user such as the operation and maintenance personnel can successfully log in to the IoT device directly by obtaining the stored device password of the IoT device, without requiring the password user such as the operation and maintenance personnel to memorize the device password of the IoT device.

Description

Technical field[0001]This application relates to the Internet of Things technology, in particular to password management methods and devices.Background technique[0002]In the Internet of Things, the number of Internet of Things devices is huge and widely distributed. Under this premise, the security management of IoT devices is particularly important. At present, when IoT devices are connected to the physical network system, in order to ensure the access security of the IoT devices, it is often necessary to authenticate the IoT devices according to the traditional knowledge factor authentication method.[0003]When the IoT device is authenticated according to the traditional knowledge factor authentication method, the operation and maintenance personnel of the IoT system are required to enter the user name and device password (equivalent to a password) of the IoT device. For the operation and maintenance personnel of the Internet of Things system, it is difficult to remember the device...
