Example Embodiment

[0077] Example one

[0078] The present invention provides a use of symmetric cryptography to enhance the MQTT protocol identity authentication method, which is applied to an identity authentication system, which includes quantum random number generators, quantum exchange cryptos, quantum keyfilling machines, quantum password management services System, Internet of Things terminal, security key chip, and Internet of Things platform.

[0079] The IoT terminal can be publisher in the MQTT protocol, or a subscriber in the MQTT protocol. The Internet of Things platform can be a proxy in the MQTT protocol. During the process of accessing the Internet of Things terminal, the Internet of Things platform needs to be certified to the Internet of Things terminal. If the authentication is passed, the Internet terminal can be transmitted to the Internet of Things platform, for example, the Internet of Things terminal can be connected Platform publishing messages, you can also subscribe to oth...

Abstract

The invention provides a method for enhancing MQTT protocol identity authentication by using a symmetric cryptographic technology, which comprises the following steps of: performing first identity authentication from an Internet of Things terminal to an Internet of Things platform: charging a quantum key into a quantum safety chip by a quantum key charging machine, and recording and storing a corresponding relationship between the charging safety chip and the key, the Internet of Things terminal calls a quantum key in a chip to construct an identity authentication request message to the Internet of Things platform, the Internet of Things platform obtains symmetry, carries out decryption and identity comparison, generates a login token after successful authentication, and returns a verification message to the terminal; second identity authentication: the Internet of Things platform applies for a key according to the terminal ID and constructs an identity authentication request message to the terminal; and the terminal decrypts and verifies the platform ID and the login token. The invention further provides a system and equipment corresponding to the method. The invention has the advantages that identity authentication is performed by using a key set symmetric algorithm in the quantum safety chip, one key is pad at a time, a third party does not need to issue and authenticate a digital certificate. Therefore, the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of security application products, and in particular relates to a method for enhancing MQTT protocol identity authentication by using symmetric encryption technology. 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 gener...
