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 configuration 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 targets , hackers seize on the vulnerabilities of operating 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 , 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 software and employ all license models offered by Code- Meter . This feature enables them to create additional revenue streams for their Intellectual Property .
