Abstract

Disclosed in the present invention are an encryption method and system for Internet of Things data transmission, the method comprising: an access node receiving first encryption indication information and second encryption indication information that is issued by an aggregating unit, and forwarding the first encryption indication information to an Internet of Things terminal which the first encryption indication information indicates; according to a device identifier of the Internet of Things terminal and a time point for reporting data, the Internet of Things terminal signing and encrypting data to be sent so as to acquire a first data packet, and when the time point for reporting data is reached, sending the first data packet to the access node; the access node acquiring the device type of the Internet of Things terminal from the first data packet, and when the device type of the Internet of Things terminal is a device type that is indicated by the second encryption indication information, signing and encrypting the first data packet according to a node identifier of the access node so as to obtain a second data packet, and sending the second data packet to the aggregating unit. The embodiments of the present invention may increase the safety of communication over a transmission link, reduce the risk of theft and decryption, and increase the security of data transmission.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an encryption method and system for data transmission of the Internet of Things. Background technique [0002] The Internet of Things manages a large number of Internet of Things terminals. The Internet of Things terminals are connected to the Internet through access nodes to report the collected data to the aggregation unit, which completes the analysis and processing of the data, and finally realizes the monitoring of the Internet of Things terminals. control, management, etc. During data transmission, if there is no encryption, it is easy to cause data leakage, and attackers can easily steal the data. The current encryption method generally uses a fixed encryption algorithm for IoT terminals, and uses an asymmetric decryption algorithm for decryption at the convergence unit. This encryption and decryption method has problems such as easy cracking and low securi...
