Abstract

The invention provides a message data encryption method and system, an internet of things server and an internet of things terminal. The message data encryption method comprises the steps that the internet of things server acquires identification information; the internet of things server determines an encryption algorithm and parameters according to the identification information; and the internet of things server encrypts message data according to the encryption algorithm and the parameters and transmits the encrypted message data and the identification information to the internet of things terminal. According to the message data encryption method, security of internet of things communication can be enhanced and disclosure of privacy of users can be avoided.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to an encryption method and system for message data, an Internet of Things server and an Internet of Things terminal. Background technique [0002] With the continuous development of the Internet of Things technology, there are more and more applications and terminals of the Internet of Things, and the communication security of the Internet of Things is becoming more and more important. When the IoT terminal communicates, it often contains the private information of the IoT terminal, or contains the control strategy for controlling the IoT terminal. If the communication of the IoT terminal is intercepted, it may cause greater harm. Therefore, it becomes necessary to encrypt the communication of the IoT terminal. [0003] Currently, message data can be encrypted using various encryption algorithms, for example, digital signature algorithm DSA, advanced encrypt...
