Information security method and system for remote meter reading of wireless gas meter

摘要

An information security method and system for remote meter reading of a wireless gas meter is provided. An information security method according to an embodiment of the present invention includes issuing a secure element (SE) in which a second security key is embedded using a first security key injected into a hardware security module; And when the SE is installed in the smart meter, issuing a third security key using the second security key. By this, physical security modules such as Secure Element (SE) and Hardware Security Module (HSM) are applied to the remote meter reading of a wireless gas meter, and a high level of security is applied through two-way authentication to prevent the possibility of data forgery and reliability. It can be secured and can help protect personal information and privacy. In addition, by providing a lightweight information security method and system that can be combined with low-power wide-area communication networks such as LoRaWAN and NBIoT in remote meter reading of wireless gas meters, it is possible to efficiently manage large-scale facilities installed with low-power wide-area communication networks.
