Embodiment

[0073] In this embodiment, a production and testing system for smart meters of the Internet of Things, such as figure 1 As shown, the meter terminal 1, the operation and maintenance server terminal 2, and the cloud 3 are connected sequentially through encrypted communication. The trusted test tool 4 is connected to the meter terminal, and the trusted test tool is connected to the cloud terminal through encrypted communication. All the content programmed into the MCU controller is verified, and all communication is encrypted communication based on identity authentication, which ensures the safety of the production and testing process of the meter terminal.

[0074] The meter side includes the MCU controller, such as figure 2 As shown, the MCU controller includes a secure world part 5 and a non-secure world part 6, a trusted execution environment 7 is deployed in the secure world part, a non-secure environment 8 is deployed in the non-secure world part, and a security Kernel m...

Abstract

The invention discloses an Internet of Things intelligent meter production test system and a safety protection method. The problems that an existing meter lacks security and secrecy measures in the production test link, and information leakage exists are solved. The system comprises a meter end, an operation and maintenance server end and a cloud end which are sequentially connected through encryption communication, and a credible test tool is connected to the meter end and connected with a cloud end through encryption communication. In the production test period of the meter end, the contentcontacted by an operator is encrypted, all the content burnt into the MCU controller is verified, and all the communication is encrypted communication based on identity authentication, so that the leakage risk is reduced from the source.

Description

technical field [0001] The invention relates to the technical field of meter safety, in particular to an Internet of Things smart meter production test system and a safety protection method. Background technique [0002] With the development of Internet of Things technology, the smart meter industry has realized wireless remote monitoring, including data collection and uploading, local storage, abnormal monitoring, remote upgrade, valve control, etc. The current mainstream solution uses wireless communication modules to exchange data with application platforms. Due to considerations of cost and operation and maintenance, the safety part is not paid much attention to. Most of the meter devices on the market do not have safety protection measures. are exposed to attackers. [0003] Metering equipment usually uses an MCU without a secure core architecture to execute code on the bare metal, without a secure software architecture, and without a trusted MCU internal execution env...
