Abstract

The present invention proposes a technique to enable centralization and security for secure communications in industrial applications. Implementations of a global discover server (GDS) provides management of certificate operations for secure communications. The GDS allows OLE for process control (OPC) application to register with a central management system and securely request certificate signing, renewal, revocation and ability to share trust and revocation list. The GDS allows OPC UA server to be visible to OPC UA clients for browsing and communication.

GLOBAL DISCOVER SERVER AGENT

BACKGROUND

The present invention relates generally to object linking embedding (OLE) for process control unified architecture (OPC UA) and more particularly to utilization of global discover server (GDS) with the OPC UA.

OPC UA is a platform independent open protocol that includes a standard architecture for ensuring secure communication system. This security platform is based on the widely utilized public key encryption (PKI) technologies, which require the creation and distribution of security certificates and associated private keys. The security of the system rests on the reliability of the processes utilized to authorize requests for new certificates and to distribute them to the requestors.

A conventional technique includes implementing certificate management for secure communication in industrial applications. However, the conventional technique is complex and difficult for users to follow and understand.

It would be desirable to have an efficient technique for users for secure communication in the industrial applications.

and revocation list. The GDS allows OPC UA server to be visible to OPC UA clients for browsing and communication. Secure communication platforms may be involved in OPC UA communications as a common platform and language for interoperability between its many and varied controller offerings and as a common language for all of its products to start interacting together. The invention provides a clear and straightforward way for customers to...
