Equipment authentication method, air card writing method and equipment authentication device

Abstract

The embodiment of the invention discloses an equipment authentication method, an air card writing method and an equipment authentication device, and the method comprises the steps that an authentication platform receives an equipment authentication request sent by a service platform, and the equipment authentication request comprises an IMSI and authentication information of to-be-authenticated equipment; and an equipment public key of the equipment is determined according to the IMSI of the equipment and the equipment public key corresponding to each IMSI stored in the authentication platform, and an authentication success message is sent if the authentication information is verified to be valid according to the equipment public key of the equipment. Therefore, on one hand, an asymmetricsecret key mechanism is adopted to carry out equipment authentication; the authentication safety can be effectively improved; on the other hand, the authentication information is generated according to the equipment private key of the equipment; and the authentication platform stores the equipment public keys corresponding to the IMSIs, so that if the authentication platform cannot successfully verify the authentication information by utilizing the equipment public keys matched with the IMSIs of the equipment, the IMSIs of the equipment are not matched with the equipment private keys, and theseparation of the machine and the card is effectively detected.

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.
