A method of encrypting data transmission

Abstract

The present invention relates to the field of communication technology, and provides an encrypted data transmission method, comprising the following steps: S1, setting the number of bytes to N i2 The body of the message is in N i4 Channels are freely selected for transmission, using a timing counter to generate a random number N i1 , the number of bytes to be transferred is N i2 The message body according to the random number N i1 Randomly split into N i3 Segmentation message body segmentation data packet; S2, the N completed by splitting the previous step i3 Segmented message body segmented data packets are randomly arranged out of order by the encoder and then dynamically encrypted and random multi-channel transmission; S3, message body restoration, the receiving end receives each segmented message body segmented data packet and stores it and decrypts it through the decoder Restore the true value of the data, that is, reorganize the segmented data of each segment of the message body through the packet sequence number and the out-of-sequence arrangement rule to splice the complete message body data in sequence. The invention solves the problem that the encryption method of the existing intelligent security system is relatively simple and easy to be deciphered, and the intercepted information has potential safety hazards.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an encrypted data transmission method. Background technique [0002] At present, the requirements for security in the process of data transmission are getting higher and higher. In the existing data transmission technology, the following two methods are generally used to ensure the security of data, namely: encrypt the plaintext data before transmission, or perform identity authentication on both parties of the data transmission before transmitting the data. In the prior art, one of the above-mentioned methods can be used alone, but usually the two methods are used in combination, that is, the plaintext data is encrypted and transmitted after the identity authentication of both parties. The specific method of encrypting the plaintext data and then transmitting it is: the sending end uses a certain key, uses a security algorithm to process the key and the plaintext data, o...

Problems solved by technology

It can be seen that the security algorithm and key in the existing data transmission technology are fixed, which makes the security of data transmission low.

Especially in the field of smart security, with the wide application of smart home, the data transmitted by the transmitter and receiver of the smart home system is usually encrypted and transmitted through DES, AES, RSA, MD5, and the data is transmitted in a single channel. Encrypting the data is easy to be stolen by criminals and cracked, so that criminals can control smart home products at will and commit crimes, posing a great threat to users' property and personal safety
