Embodiment

[0094] In this embodiment, a security protection system for Internet of Things equipment includes communication-connected equipment and servers, and the equipment includes an MCU controller, such as figure 1 As shown, the MCU controller includes safe area 1 and non-safe area 2,

[0095] The safe area can access all resources, and the non-safe area can only access the resources of the non-safe area and is forbidden to access the resources of the safe area. When the non-safe area illegally accesses the resources of the safe area, the MCU controller intercepts and generates an exception from the hardware. The safe area and the non-safe area can be switched, and are strictly monitored by the MCU controller.

[0096] In addition, set the read-write protection function for the MCU controller, and the external debugging tool cannot debug, and cannot read and modify the contents of the flash, sram, and backup registers. When the read protection is released, the hardware will automatic...

Abstract

The invention discloses an Internet-of-Things equipment safety protection system and method. The problems that in the prior art, security holes exist in hardware and software of Internet-of-Things equipment, the security of communication encryption and decryption is not high, and the efficiency ratio is low are solved. The system comprises a device and a server, the device comprises an MCU controller, the MCU controller comprises a secure area and a non-secure area, a trusted execution environment is deployed in the secure area, a non-secure environment is deployed in the non-secure area, and a startup loading module, a secure kernel module, a secure component module, a trusted application and a secure API interface module are arranged in the trusted execution environment. A user application and a non-secure kernel module are arranged in the non-secure environment. Sensitive data storage access is protected through three-layer protection measures. Information encryption and decryption between the equipment and the server are verified by adopting an identity token. Security protection is carried out from equipment hardware, software, storage access and communication, and hardware control, software cracking and information stealing are prevented.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things security, in particular to a security protection system and method for Internet of Things devices. Background technique [0002] With the development of Internet of Things technology, the smart device industry has realized wireless remote monitoring, including data collection and uploading, local storage, abnormal monitoring, remote upgrade, remote control, etc. The current mainstream solution uses wireless communication modules to exchange data with cloud application platforms. Due to considerations of cost and operation and maintenance, the security part is not paid much attention to. Most IoT devices on the market do not have security protection measures. Their communication links and MCU Everything inside is exposed to an attacker. [0003] IoT devices usually use an MCU without a secure core architecture, execute code on bare metal, have no secure software architecture, an...
