A security authentication and data communication system between IoT devices

Abstract

The invention relates to the technical field of the communication security, especially a safety authentication and data communication system between internet of things equipment. The system comprisesa data injection system for producing IDs, certificates, and public and private key pairs of credible internet of things equipment, and commonly injecting the IDs, the certificates, the public keys and the private keys and the public key of the data injection system into the credible internet of things equipment; the credible internet of things equipment for storing various data sent by the data injection system, wherein the IDs, the certificates and the public and private key pairs between various credible internet of things equipment are different except that the public key of the data injection system is same in the data stored in different credible internet of things equipment. Through the technical scheme disclosed by the invention, the data storage security is improved, the maliciousattack is prevented, and the computation efficiency in the authentication process and the encryption process is improved; the technical scheme disclosed by the invention simplifies the interaction frequency and data size required by inter-equipment handshake and identity authentication, and improves the communication efficiency among various internet of things equipment; and the above scheme is easy to realize and convenient for transplant.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a security authentication and data communication system between Internet of Things devices. Background technique [0002] With the development of the Internet of Things technology, more and more devices are connected to the Internet. These devices not only provide a variety of convenient services for people's lives, but also become tools that can be seen everywhere in the work, followed by The security issues of the industry have also gradually gained people's attention. [0003] The transmission of commands and data is required between IoT devices. However, the current IoT devices seldom perform mutual identity authentication, and most of the transmitted commands and data are in plain text, which makes the security of the entire system extremely low and vulnerable to The attack of criminals. Since there is no identity authentication between devices, attackers ca...

Problems solved by technology

In a few systems with device identity authentication and data transmission encryption, software is generally used to implement the method defined by SSL / TLS for handshake and data transmission between devices. This method has many interactions and a large amount of data transmission. And the data encryption and decryption algorithm of the software is adopted, and the application among the IoT devices increases the overhead of the equipment and the system, greatly reducing the working efficiency of the equipment
