A method and apparatus for cloud communication on Internet of things

Abstract

The invention discloses a low-power consumption IoT hardware and cloud communication method and a device thereof, which give consideration to both performance and safety, and relates to the IoT field.The invention solves the problem of supporting the channel TLS and the content encryption on the hardware chip with low performance and low power consumption. The technical proposal of the inventionis applicable to a low-power consumption Internet of Things hardware chip, and the performance is insufficient to realize the standard TLS full-channel encryption and the secure asymmetric encryptionmode to encrypt the information content. The technical proposal of the invention mainly takes into account the performance, and simultaneously solves the communication safety of hardware chips and clouds. The technical scheme of the invention realizes the protection of the communication safety of the internet of things equipment by adopting the security assurance means such as the lightweight TLSproduct, the ECC elliptic curve encryption algorithm and the like. Through the implementation of the scheme and the test on the low-end chip ESP8266, the lightweight TLS based on ECC elliptic curve encryption algorithm is implemented to support HTTP and MQTT communication, which guarantees the security risk of 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...

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.
