SECURE NETWORK & ENCRYPTION
The Anybus CompactCom B40 PROFINET-IRT IIoT Secure Brick is a ready-made security solution which enables network-secure, encrypted communication on OPC UA Secure channels, and Secure MQTT communication. It also enables secure access to the embedded web server and secure file transfer.
In order to secure the network communication over TLS, the device is equipped with a security chip providing secure key storage together with a hardware-accelerated cryptographic engine.
The embedded web server includes web pages for security configuration such as certificate installation and user account management.
CERTIFICATES & SECURE COMMUNICATION
Certificates are a main component in secure communication. They are used to identify the owner of the certificate. A node will trust a certificate if it trusts the Certificate Authority (CA) that has issued the certificate. Trusted certificates are used to ensure secure communication.
Which certificates to use, depend on the installation. HMS Networks offers a tool that generates device and CA certificates, to be used during development.
