Internet of things security authentication chip and access control method based on chip

Abstract

The invention discloses an Internet of things security authentication chip and an access control method based on the chip. The security authentication chip comprises a central processing unit, and an algorithm module, a memory module, an input / output module, a random number generator and an initialization module which are connected with the central processing unit. The access control method comprises an initialization method for the security authentication chip and a security authentication method. The security authentication chip is mounted in a certain device; after the security authentication chip enters a working state, initialization is carried out; after the initialization, the security authentication chip generates a unique identity and an access key for other device, wherein the unique identity and the access key are used for accessing the device; the other device carries out data interaction with the device on which the chip is mounted; and after the security authentication is carried out on the other device by the chip successfully, the device on which the security authentication chip is mounted can be accessed. The chip and the method have the advantages that any one device which is equipped with the security authentication chip and is connected with the Internet of things can control the access of the other device independently, securely and reliably, and the control of an authentication system of a third party is avoided.

Description

technical field [0001] The invention relates to security authentication of Internet of Things devices, in particular to an Internet of Things security authentication chip and an access control method, which are used to solve the problem of secure access and control of Internet of Things devices. Background technique [0002] The Internet of Things is another technology and application development hotspot that has attracted global attention after the Internet in recent years. As the name implies, the Internet of Things is an interconnection based on objects (devices). Therefore, as we all know, the scale of Internet of Things applications based on devices will be far greater than that of Internet applications based on people. However, looking at the current application of the Internet of Things, it is just like the development state of the Internet in the 1990s. At that time, a large number of applications began to be launched on the Internet, but the security risks of these ...

Problems solved by technology

If there is only one device for some IoT applications, it is obviously not economical to use an IoT security authentication system to manage

In fact, a large number of IoT applications may only manage the access authentication of a device
