Problems solved by technology

[0004] However, when performing authentication, both the MQTT terminal and the MQTT server need to apply for a certificate, import the certificate into their own devices, and need to manage the imported certificate, which will increase the processing complexity of the MQTT terminal and MQTT server in the authentication process

Embodiment Construction

[0073] 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.

[0074] The application of the present invention provides an authentication method and device. The method can be applied to a network system running the MQTT protocol, and is jointly implemented by a terminal and a server in the network system. Wherein, a server in the network system may be called an MQTT server, and a terminal in the network system may be called an MQTT terminal. see figure 1 , figure 1 A block diagram of an MQTT protocol network system provided by an embodiment ...

Abstract

The embodiment of the invention provides an authentication method and an authentication device, which can be applied to a MQTT (Message Queuing Telemetry Transport) terminal, wherein the MQTT terminalcan send an authentication request to a MQTT server, obtains a verification character string according to a prestored private key and an encrypted character string sent by the MQTT server, and sendsthe verification character string to the MQTT server. The MQTT server using the authentication method can encrypt an acquired random character string according to a public key corresponding to the MQTT terminal to obtain the encrypted character string and send the encrypted character string to the MQTT terminal, and then, can obtain an authentication result of the MQTT terminal according to the random character string and the received verification character string. Based on the processing above, the MQTT terminal and the MQTT server can realize authentication of the MQTT terminal without executing operations of application, importing and management of a certificate, thus, processing complexity of the MQTT terminal and the MQTT server in an authentication process can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an authentication method and device. Background technique [0002] The MQTT (Message Queuing Telemetry Transport) protocol is a communication protocol based on the publish / subscribe model, which is built on the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol superior. MQTT can provide real-time and reliable message services for connected terminals with less code and limited bandwidth. [0003] In the MQTT protocol, a server (may be referred to as an MQTT server) needs to authenticate an accessed terminal (may be referred to as an MQTT terminal). After successful authentication, the MQTT terminal publishes or subscribes to messages through the MQTT server. In order to improve the security of transmitted data during the authentication process, the prior art generally uses a TLS (Transport Layer Security, Transport Layer Security) protocol f...
