Configuring the gateway

Configuration of data transfer from the OPC UA server to the MQTT broker via Kaspersky IoT Secure Gateway 100 consists of the following steps:

1. Generating an encryption key and certificates for connection over the OPC UA protocol

   An encryption key and certificates must be generated if a secure OPC UA connection is used.

   Specification defining the protocols and mechanism for data transfer in industrial networks as well as interaction between devices in these networks.

   Data structure with a digital signature containing a public encryption key and the ID of the client or server.

   Component of a pair of encryption keys used for asymmetric encryption. Keys can be public or private.

2. Configuring nodes for data transfer over the OPC UA protocol on the OPC UA server

   You can read about the OPC UA protocol specification on the developer's website. Kaspersky IoT Secure Gateway 100 version 2.0 supports OPC UA protocol version 1.04.

3. Generating an encryption key and certificates for connection over the MQTT protocol

   You will need to generate an encryption key and certificate for the MQTT client, and prepare a file containing the certificate chain that was used to sign the server certificate.

   Combination of any number of intermediate certificates between the end-entity certificate and the root certificate.

   A network protocol that works on top of the TCP/IP protocol stack to exchange messages between devices on the internet of things.

4. Configuring the Kaspersky IoT Secure Gateway 100 settings for transferring data from the OPC UA server to the MQTT broker
