CLIENT ID 請任意取一個名稱，不要與其他用戶端名稱重複即可。(~00:55) 54. MY THING NAME 要用前面建立的 IoT Thing 的名稱: my-IoT。(~01:02) 55. 底下的 ROOT CA file name，IoT Certificate file name，以及 IoT private key filename。 56. 前面在建立 IoT Thing 安全憑證過程中，有下載了 Root CA 及 IoT 安全憑證幾個檔案，請將 檔案名稱填寫到這裡。 最後是修改 點 C，系統會將範例程式執行檔放到 root file system 的 usr/bin 目錄下，並將憑證檔案放到 usr/certs 目錄下。 這裡請將憑證指定目錄改為 相對路徑的 ../certs。 接著打 make 直接進行編譯。 編譯需要幾分鐘的時間，影片跳過了編譯部分。 接下來，將編譯好的應用程序複製到 rootfs 的 /usr/bin 目錄下。 然後將根憑證及 IoT 安全憑證檔案複製到 rootfs 的 /usr/certs 目錄下。這裡已經事先複製好了。完成後到 BSP Linux 目錄下，編譯 kernel。 將 kernel 上傳到 IoT 開發板上面執行。 下 ifconfig + udhcpc 指令連接網絡。 由於憑證有時效性問題，需要修改系統時間，以免因為憑證過期導致無法連接。 進到 usr/bin 目錄下，執行 AWS用戶端範例程序。 可以看到用戶端已經成功連接 AWS 雲端。這個範例會不斷地發佈並且接收訊息。 - 更多產品資訊，請至新唐科技網站 https://bit.ly/3hVdcmC 購買管道：https://direct.nuvoton.com/tw/numaker-nuc980-iiot 聯絡我們： SalesSupport@nuvoton.com

Secure Smart Metering Communication Reference Design Hi everybody, today we are going to introduce a reference design of Smart-Metering communication card based on NuMicro M2351 Series microcontroller. You can find useful security features based on the Arm Cortex-M23 CPU core with Nuvoton’s in-house technology integration. The auto-metering is an infrastructure for automatic, remotely, wire or wireless meter data reading. It’s highly possible to be intervened if there is no security mechanism. That is a very typical IoT security issue in the IoT era. In many countries, there are a lot of Auto-Metering Infrastructure (AMI) projects being undertaken by main electricity power companies worldwide. Most projects start from upgrading the communication modem cards as the first step rather than retiring the meters. The modem card can play as a gateway to monitor the incorrect device operation and data transmission security. Issues of modem card security are covering: First, a limited performance due to crypto computation efficiency Second, speed limitation due to interface choice The third, cost burden due to extra hardware modules for different communication protocols Nuvoton’s reference design of Secure Smart Meter Communication is an end-to-end security solution for AMI. With the collaboration with SPI-Korea, the solution incorporates a lot of advantages such as TrustZone security for firmware, a range of interfaces for device communication, secure over-the-air firmware update, and remote management. With the complete hardware specification of M2351, a security software company, SPI-Korea, can easily implement their secure AMI solution for modem card which connects meters and cloud servers. M2351 also contributes the crypto acceleration during the cryptographic computing in order to save CPU time for different communication protocol modules by its powerful hardware functionalities during message transmission outside of a microcontroller unit. SPI-Korea has developed a range of Armv8-M TrustZone based technologies. Her expertise covers Boot Manager, Key Manager, and Device Manager, which is very useful for microcontroller security and certainly shows the stability of a microcontroller device. Also, they are certified by Korea Electricity Company. We hope this successful experience can be further adopted in other areas worldwide because it’s a secure, accurate and environmentally safe solution for AMI. This slide is a picture for SPI-Korea AMI modem card design. NuMicro Family microcontrollers can be utilized for designs of auto-metering infrastructure devices. We start from AMI modem card and we are confident to support meters of any next-generation of AMI. We now integrate M23-based microcontroller with M4-based or Arm9-based microcontroller as a proposal for next-generation modem card of Korea AMI and we hope to provide high-performing cost-effective solution for all AMI devices in the future. - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC contact us: SalesSupport@nuvoton.com
