OPC UA Security and Certificate Management
Description
The secure operation of modern industrial networks is a major challenge. Communication protocols that allow protected and authenticated connections are needed to secure these networks. OPC UA, for example, is such a secure, industrial communication protocol.
With OPC UA, as with many other protocols, these connections are secured through the use of certificates that enable a secure authentication of communication participants. In practice, however, their use requires configuration and management effort.
OPC UA and certificate management
In order to keep this effort as low as possible, the OPC UA standard already includes functions for managing these certificates, even integrated into the protocol. A so-called "Global Discovery Server", or GDS for short, with certificate management support is required to provide this in practice.
open62541-based GDS
The open62541-based GDS is an implementation of such a Global Discovery Server with certificate management. It offers the management of registered applications in an OPC UA network, as well as the management and distribution of certificates and trust lists.
The GDS is based on the open-source open62541 implementation of the OPC UA standard.
We offer…
We carry out research and development projects on the application of secure trust infrastructures in industrial networks and make this knowledge and experience available.
Planning and concept development
We plan deployment scenarios for OPC UA environments and work with our partners and customers to develop concepts for setting up and operating secure communication networks.
Security analyses
We analyze new and existing OPC UA environments for their security properties. In doing so, we not only incorporate the latest scientific findings, but also carry out targeted technical tests to evaluate the security of the environments.
Concepts and implementation of secure OPC UA
We carry out development work based on OPC UA in order to implement use cases for secure industrial networks. We also create suitable concepts for certificate management and the use of public key infrastructures (PKI).
Certificate management using the GDS
We develop and promote the implementation of certificate management in OPC UA using the open62541 stack and our own GDS implementation.
