Embodiment approach

[0046] According to an embodiment of the present invention, the unique identifier of the device is a media access control MAC address of the device, and the hardware security chip identifier is a hardware security chip address chipID.

[0047] Figure 2B yes Figure 2A The flow chart of the steps in sending an upgrade request to the server according to the device's unique identifier and the device's hardware security chip identifier. As shown in Figure 2, in step S220, sending an upgrade request to the server according to the unique identifier of the device and the hardware security chip identifier of the device includes: in step S222, checking the MAC address of the device and the hardware security chip The chipID performs a hash HASH algorithm to obtain a hash HASH value. In step S224, the HASH value and the MAC address of the device are sent to the server to request an upgrade to the server.

[0048] In the above scheme, the terminal performs a hash algorithm on the MAC a...

Abstract

The invention relates to the technical field of Internet of Things and discloses a method and device for upgrading equipment, which are used for an equipment end. The method comprises the following steps: displaying a unique identifier of the equipment and a hardware safety chip identifier of the equipment; receiving an encrypted upgrade package; analyzing the received encrypted upgrade package to obtain a decrypted upgrade package; upgrading the equipment by utilizing the decrypted upgrade package; and upgrading the equipment accessed into a network so as to improve the safety protection grade of the equipment.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a method and a device for upgrading equipment. Background technique [0002] The extensive promotion of the Internet of Things has increased the types of devices and terminals connected to the network, and the access of smart home appliances has improved the user experience and the effect of the device, but at the same time there are security risks. [0003] In the prior art, by adding a programmable hardware security chip to the communication module of the device, a fixed symmetric key or an asymmetric key is used for key negotiation between the server and the device, and then the symmetric key is used for encrypted communication . The security protection scheme is fixed, and the security level cannot be improved when dealing with new threats, and the policy response cannot be carried out. Contents of the invention [0004] The purpose of the present i...
