HTTPS: A secure communication protocol based on HTTP and encrypted using SSL. Modbus: Devices that access the platform with Modbus via IoT edge nodes (or child devices that connect to the platform through gateways) are indirectly connected devices.
Port 5683 is used for unencrypted access, whereas port 5684 is used for encrypted access.
Options: PAAS: In this mode, data is not encrypted and transmitted in plaintext, which is insecure. You are advised to use a more secure data encryption mode. PLAIN: SASL/PLAIN authentication. You must enter the username and password.
DTLS is used for encrypted transmission. LwM2M Short for Lightweight Machine to Machine, an IoT protocol defined by Open Mobile Alliance (OMA). It is mainly used for NB-IoT devices with limited resources (such as limited storage and power supply).
MQTTS devices communicate with the platform using encrypted data transmission. Service Flow MQTT devices communicate with the platform without data encryption. For security purposes, MQTTS access is recommended.

Password Enter the encrypted device secret obtained in 2. Click the SSL/TLS tab and then select Enable SSL/TLS. Recommended: Set Protocol to TLSv1.2.
{private key} Private key encrypted using the RSA algorithm. You can upload a private key file in .pem or .key format. rsa_padding_mode:pss Use the Probabilistic Signature Scheme (PSS) padding mode.
{private key} Private key encrypted using the RSA algorithm. You can upload a private key file in .pem or .key format. openssl base64 Encode the signature result using Base64 for transmission and storage.
However, you are advised to use HTTPS for encrypted transmission. Can I Change the Callback URL? Yes. A callback URL can be changed.
contains the following files: NB-IoTDeviceSimulator_en.jar: simulator Californium.properties: simulator configuration file setting.properties: configuration file for connecting the simulator to the platform When a message is displayed requesting you to confirm whether to enable DTLS encrypted
Return value String Value encrypted using the HmacSHA256 algorithm.
The string encrypted using SHA-256 is 2ff821fb8a976ede7d06434395ec8c25e4100bff8b3d12d8099ef7e30b58bd4c. After a token is created, you need to configure a new token each time you modify the forwarding target. Otherwise, the token does not take effect.
Return Values String Value encrypted using the HmacSHA256 algorithm.
