Internet of things data transmission method

Abstract

The invention provides an Internet of things data transmission method. The Internet of things data transmission method comprises the following steps: S1, sending request information to a data receiving terminal by a data sending terminal, and feeding back an encrypted character string by the data receiving terminal; S2, receiving the encrypted character string by the data sending terminal, and recording time node information T2 of the received encrypted character string; S3, receiving the time node information T2 of the received encrypted character string by the data sending terminal, and forming an encryption key from the time node information T2 and the encrypted character string according to a predetermined rule; S4, encrypting message information through the encryption key by the data sending terminal, and sending the encrypted message information and the time node information T1 to the data receiving terminal according to predetermined delay time T3; S5, judging whether the received encrypted message information is legal by the data receiving terminal, if so, decrypting data, and otherwise, discarding the received information. By the Internet of things data transmission method, message data in an Internet of things platform can be effectively encrypted so as to ensure data security in an Internet of things system.

Description

technical field [0001] The invention relates to an Internet method, in particular to a data transmission method of the Internet of Things. Background technique [0002] With the development of the network, the use of the Internet of Things in modern society is becoming more and more common and important, especially for the security field. When the detection terminal sends the detected data to the monitoring terminal, the security of the data is of paramount importance. It is very important and related to the safety of production and life; such as fire monitoring, once it is intercepted or tampered with by criminals during data transmission, it will cause irreparable losses; in the existing technology, there are the following defects in the encryption algorithm for Internet of Things data transmission : The existing algorithm is complex, which causes serious time consumption in the encryption and decryption process. For the fields that require timeliness, this will bring fata...

[0002] With the development of the network, the use of the Internet of Things in modern society is becoming more and more common and important, especially for the security field. When the detection terminal sends the detected data to the monitoring terminal, the security of the data is of paramount importance. It is very important and related to the safety of production and life; such as fire monitoring, once it is intercepted or tampered with by criminals during data transmission, it will cause irreparable losses; in the existing technology, there are the following defects in the encryption algorithm for Internet of Things data transmission : The existing algorithm is complex, which causes serious time consumption in the encryption and decryption process. For the fields that require timeliness, this will bring fatal consequences. For example, in the fire protection field mentioned above, if the algorithm is simplified, it will lead to The transmitted data is extremely insecure and there are serious security risks
