Encrypted data transmission method

Abstract

FIELD OF THE INVENTION that present invention relate to the field of communications technology, A method for encrypt data transmission comprises the following steps: S1, a message body with the numberof bytes set as Ni2 is transmitted freely in Ni4 channels, a random number Ni1 is generated by using a timing counter, and the message body with the number of bytes set as Ni2 to be transmitted is randomly divided into Ni3 segment message body segmented data packets according to the random number Ni1; S2, the Ni3 segment message body segmented data packets separated in the previous step are randomly misordered by an encoder, and then are dynamically encrypted and transmitted in a random multi-channel manner; 3, message body is restored, wherein the receiving end receives the segmented data packets of each segment of the message body, stores and decrypts the true value of the restored data through a decoder, namely, reorganizing the segmented data of each segment of the message body into complete message body data according to a packet sequence number and a misordering rule, and sequentially splicing the segmented data of each segment of the message body. The invention solves the problem that the encryption mode of the existing intelligent security system is simple and easy to cracke and the intercepted information has the hidden danger of safety.

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
