Embodiment Construction
[0067] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0068] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a device identification method of the present application, which is applied to a control device, and may specifically include the following steps:
[0069] Step 101, acquire the instruction data to be sent, first key information corresponding to the target receiving end, and a preset network identification code of the network where the target receiving end is located.
[0070] In the embodiment of the present invention, the key information and the preset network identification code in the present invention can be managed by the key server in the networking, for example, when networking the control device and multiple sla...

The embodiment of the present application provides a device identification method and device and a storage medium, which are applied to control devices. The method includes: obtaining the instruction data to be sent, the first key information corresponding to the target receiving end, and the target receiving end The preset network identification code of the network where it is located, generates the plaintext data to be sent according to the instruction data to be sent and the preset network identification code, and encrypts the plaintext data to be sent by the first key information to obtain the ciphertext data to be sent , sending the ciphertext data to be sent to the designated device, so that the designated device can identify the designated device according to the obtained network identification code to be determined after decrypting the ciphertext data to be sent through the stored second key information Whether it is the target receiver. In this way, a preset network identification code can be set in the ciphertext data to be sent, and the target receiving end can be identified by using the decrypted network identification code to be determined, so that the number of devices in the network is not limited.
Description
technical field [0001] The present application relates to the communication field, in particular to a device identification method and device and a storage medium. Background technique [0002] The networking mode of the existing underlying devices is usually: multiple slave devices can be connected in parallel on the bus of the control device (such as PLC or RTU, etc.), and the bus can include RS485 / 232, can bus. Data transmission is carried out on the bus through modbus, can protocol and some custom protocols. At present, the corresponding device identification can be set for each slave device in the protocol, so that the control device can access each slave device according to the device identification. However, considering that the existing device identification usually has a limited number of bytes, the number of slave devices in the networking is limited. Contents of the invention [0003] In view of the above problems, the embodiments of the present application pro...
