Certificates

Device Trust Manager issues x.509 certificates to devices to establish secure communication and authenticate with the platform. During provisioning, a device receives a bootstrap certificate, which verifies the device's identity and initiates secure communication with Device Trust Manager. As the device continues to operate, it may request operational certificates for short-term, specific operations as needed throughout its lifecycle.
