Problems solved by technology

[0003] Compared with static key encryption, this dynamic key encryption method has higher security and is not easy to be intercepted and cracked. However, each time a dynamic key needs to send a special message to distribute the dynamic key to the receiving end, it increases network security. burden

Embodiment

[0044] 1. The user sets his own password for each lamp in the network, and the password is saved locally;

[0045] 2. When the sender needs to send data, frame according to the protocol;

[0046] 3. Generate an 8-bit key parameter I according to the sent frame information;

[0047] 4. Read the 16bit user password stored locally as the key parameter II;

[0048] 5. For the first sending, read the preset 8bit key parameter III, if it is not the first sending, read the updated key parameter III

[0049] 6. The three key parameters are combined into a 16-bit number, which is sent to the local key generator to generate the sending key;

[0050] 7. Use the sending key to encrypt the data to be transmitted and part of the frame header, add an 8-bit key parameter I to the header, and add a 16-bit CRC check digit to the tail to form a data frame and send it to the receiving end;

[0051] 8. After receiving the data, the receiving end obtains the key parameter I according to the firs...

Abstract

The invention relates to an encryption method for a communication protocol of a light control system, which belongs to the field of computers. This method adopts the method of dynamically generating key encryption at the sending and receiving ends; the sending end extracts the key parameter I dynamically generated by the data frame information of the sending end to ensure that the key is different each time; the private password set by the user is used as the key parameter II to participate in the encryption Key generation, higher security; the key parameter III for the next transmission is included in the data frame sent this time, and the receiving end is notified to update the key parameter III. For the first transmission, the key parameter III uses a preset initial value to generate a key, and each time the sending and receiving process is completed, both the sending and receiving ends update the key parameter III. The present invention can reduce special key distribution messages. In addition, using the private password set by each user as a key parameter to participate in key generation can improve security.

Description

technical field [0001] The invention belongs to the field of computers and relates to a communication protocol encryption method of a light control system. Background technique [0002] In the existing communication protocol of the lighting control system, the existing dynamic encryption methods all need to periodically generate a dynamic key and send it to the receiving end after being encrypted with the public key. Then the transmission of encrypted data is carried out. After a certain period of time, the sender sends a message again to update the dynamic key. [0003] Compared with static key encryption, this dynamic key encryption method has higher security and is not easy to be intercepted and cracked. However, each dynamic key needs to send a special message to distribute the dynamic key to the receiving end, which increases network security. burden. Contents of the invention [0004] In view of this, the object of the present invention is to provide a communicati...
