A kind of Internet of things cloud communication method and device thereof

Abstract

The invention discloses a low-power Internet of Things hardware and cloud communication method and its device that take into account both performance and safety, and relates to the field of the Internet of Things. The invention solves the problem of supporting channel TLS and content on a hardware chip with low performance and low power consumption. Encryption support. The technical scheme of the present invention is suitable for low-power Internet of Things hardware chips, and its performance is not enough to realize standard TLS full-channel encryption and secure asymmetric encryption to encrypt information content. The technical solution of the present invention mainly takes performance into consideration, and at the same time solves hardware chip and cloud communication security. The technical solution of the present invention realizes the protection of the communication security of the Internet of Things equipment by adopting security assurance means such as lightweight TLS products and ECC elliptic curve encryption algorithms. Through the implementation of this scheme and the test on the low-end chip ESP8266 chip, the lightweight TLS based on the ECC elliptic curve encryption algorithm supports HTTP and MQTT communication, ensuring all-round protection against security risks in communication.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a low-power Internet of Things hardware with performance and safety in mind and a method for communicating with the cloud. Background technique [0002] The Internet of Things, namely INTERNET OF THINGS (IOT). IoT devices can be various information sensors and controllers, as well as various intelligent household appliances. IoT devices are connected to the Internet in various ways to form a huge network, realizing the extension of the Internet from people to things. The WIFI Internet of Things access method is one of the most widely used, lowest cost, and best scalable Internet of Things access methods. Generally, a WIFI IoT device directly accesses the network through a WIFI access point (WIFI ACCESS POINT, also called a WIFI access point or a wireless router). [0003] The development of the Internet of Things is facing a lot of difficulties, and security iss...

AI Technical Summary

Problems solved by technology

[0004] At present, for low-end chips in the industry, for security, it is usually only possible to implement encryption through content, which cannot fully guarantee the security issues caused by communication, and many even choose to use weak content encryption or even no encryption.

[0005] Limited by the low performance, low power consumption and low-speed communication characteristics of IoT device chips, for example, in smart home appliances, such as light bulbs, sockets and other low-end networking chip modules, there is not enough FLASH and MEM, resulting in the inability to better support the standard At the same time, the conventional RSA encryption algorithm lacks protection against common security risks such as monitoring, hijacking, tampering, packet replay, and forged nodes in the communication process.
