Credible safe starting method and system based on Internet of Things gas meter

Abstract

The invention discloses a trusted security starting method and system based on an Internet of Things gas meter, and the method comprises the steps that a security authentication platform obtains an initial Internet of Things gas meter MCU program, carries out the signature of the initial Internet of Things gas meter MCU program according to a pre-stored platform private key, and generates a signature value; before the MCU program of the Internet of Things gas meter runs each time, the MCU program of the Internet of Things gas meter sends the current MCU program of the Internet of Things gas meter to the security chip; and the security chip verifies the current Internet of Things gas meter MCU program according to the signature value and the platform public key, and authorizes the current Internet of Things gas meter MCU program to operate after the verification is passed. The signature value is generated according to the initial Internet of Things gas meter MCU program, the current Internet of Things gas meter MCU program is verified through the signature value, credible and safe starting of the Internet of Things gas meter MCU program is achieved, and it is guaranteed that the integrity of the MCU program in the Internet of Things gas meter is not damaged.

Description

technical field [0001] The invention relates to the technical field of gas, in particular to a method and system for trusted and safe start-up of a gas meter based on the Internet of Things. Background technique [0002] The Internet of Things gas meter is a new type of smart gas meter developed on the basis of the existing Internet of Things technology. It requires the combination of remote transmission technology and Internet technology to complete data exchange. The Internet of Things gas meter needs a real-time, safe and effective exchange path to realize data exchange with the gas company's gas sales management system, complete related remote meter reading, remote recharge, remote control, and real-time connection of the gas meter to the Internet. [0003] The MCU program of the Internet of Things gas meter is the basis for realizing various functions of the Internet of Things gas meter. The existing MCU program of the Internet of Things gas meter lacks information secu...
