Issuing and managing certificates

Available in Classic and VPC

Communications between your IoT equipment and Cloud IoT Core are encrypted, based on certificates. Certificates you can issue on Cloud IoT Core include the certificate, chain certificate, root certificate, and private key. It is checked if the server to access on the IoT device through the certificates is the normal Cloud IoT Core server, and the server checks if the user trying to access is normally authenticated. Once the mutual authentication is completed, encrypted communication for security will begin.
