An equipment authentication method, an air card writing method, and an equipment authentication device

Abstract

The embodiment of the present invention discloses a device authentication method, an over-the-air card writing method, and a device authentication device, including: the authentication platform receives the device authentication request sent by the service platform, and the device authentication request includes the IMSI and authentication information of the device to be authenticated; The IMSI of the device and the device public key corresponding to each IMSI stored in the authentication platform determine the device public key of the device, and if the authentication information is verified to be valid according to the device public key of the device, an authentication success message is sent. It can be seen that, on the one hand, the use of asymmetric key mechanism for device authentication can effectively improve the security of authentication. On the other hand, since the authentication information is generated based on the device private key of the device, and the authentication platform stores the device corresponding to each IMSI Therefore, if the authentication platform cannot successfully verify the authentication information with the device public key that matches the device's IMSI, it means that the device's IMSI does not match the device's private key, thereby effectively detecting the device-card separation.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an equipment authentication method, an air card writing method and an equipment authentication device. Background technique [0002] With the development of the Internet of Things and mobile Internet, more Internet of Things services (remote meter reading, smart home, etc.) Wearable devices) are constantly appearing and connected to the operator's network as a terminal. [0003] Different from users' smart phones and other terminals in the mobile communication network, in the Internet of Things, IoT devices are generally in an unattended environment and are vulnerable to attacks and damages. The IoT card containing user identity information in the device is also easily hacked Deliberate destruction or stealing is used for illegal device access, which leads to device security issues. Therefore, in order to prevent the special card from being used elsewhere, it is ...

Problems solved by technology

If the password entered by the user matches the password stored in the authentication platform, it is considered to be a legitimate device. It can be seen that the security of this authentication method is low, and it cannot effectively detect the separation of the machine card, and it is different from the integrated circuit card, fingerprint, etc. The authentication method combining authentication methods needs to add corresponding identification modules or hardware to IoT devices, which increases the authentication cost.
