Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] Token: It is a random value. Token can be used as a message sequence number to ensure that the messages exchanged between the gateway and the server can correspond one-to-one.

[0039] The network architecture of LoRaWAN is as follows: figure 1 As shown, a terminal device 100, gateways 110-130 and a server 140 are included. Here, only LoRaWAN includes 1 terminal device, 3 gateways and 1 server as an example for illustration, without other limitations.

Abstract

The embodiment of the application provides a message processing method and device, which are applied to a server in a LoRaWAN. The method comprises the following steps: a first message sent by a firstgateway is received, wherein the first message carries a first gateway identifier, a first check sequence and first check information of the first gateway; If it is determined that the first gatewaycorresponding to the first gateway identifier is an access-permitted gateway, the second check information of the first gateway identifier is determined according to a check algorithm and a first check sequence previously agreed with the first gateway. If the first check information and the second check information do not coincide, the first message is discarded. The embodiment of the present application are applied, the security of the LoRaWAN can be effectively improve.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message processing method and device. Background technique [0002] LoRa (Long Rang, long-distance) technology is a wireless modulation technology used in long-distance, low power consumption, and low-speed applications. LoRa can be used in almost all network technologies and is a general term for the long-distance low-power protocol family. In LoRaWAN (LoRa Wide Area Network, LoRa Wide Area Network), the gateway is a transparent relay, and the gateway connects the front-end terminal device and the back-end server. [0003] Wherein, when the gateway communicates with the server, the message sent by the gateway to the server carries the gateway identifier. After receiving the message sent by the gateway, the server determines whether the gateway is a gateway that allows access according to the gateway identifier in the message. Then process the message. ...
