Bolstering the built-in protections of the OPC UA protocol for secure cryptographic key
storage and novel sales concepts in the industrial world.
Security Extensions for OPC UA
Keeping cryptographic keys or other sensitive con-
figuration files, such as private RSA keys or trust
lists, in the routine file system exposes this data
to theft and tampering, especially in the modern,
connected cyber physical world. Among their
many insidious ways of compromising their tar-
gets, hackers seize on the vulnerabilities of opera-
ting systems with Trojans and other ways to sneak
into the file systems.
Unified Automation has released its OPC UA SDK
based on ANSI C with the complete integration of
CodeMeter Embedded, the runtime environment
for embedded systems like Linux Embedded,
VxWorks, QNX, and Android. This enables makers
of embedded software to use secure CodeMeter
hardware elements (USB dongles, memory cards,
or ASICs) to store cryptographic keys and trust lists.
Cryptographic keys can be used, but not read out,
and trust lists read, but not changed without the
right privileges.
Furthermore, makers of embedded software can use
the same hardware to store licenses for their soft-
ware and employ all license models offered by Code-
Meter. This feature enables them to create additional
revenue streams for their Intellectual Property.
