Increasing networking of production demands significantly higher security standards in industrial automation than has previously been the case. Threats based on malware, incorrect firmware updates, and counterfeit components can bring entire production lines to a standstill and cause significant costs.
“Our security solution improves the availability and efficiency of production systems,” says Juergen Spaenkuch, Head of Platform Security at Infineon Technologies. “It can be easily integrated into industrial automation systems to increase the protection against IT attacks and manipulation.”
The security solution consists of Infineon’s OPTIGA Trust product family security chips as a hardware-based trust anchor, together with complementary software. Security chips and software are both are available and can be optimised to customer- and application-specific needs.
Access to the system is granted only to components or machines that can identify themselves reliably and that therefore are considered trustworthy. Counterfeit replacement parts or unauthorised repair tools can be detected and rejected. The solution also secures programming or programming processes from manipulation due to malware or an incorrect software update – an aspect that will gain in importance as the remote service and remote repair of industrial facilities grows more common. The combination of security chips that are comparable to a data safe and encryption prevents the PLC code from extraction and therefore protects valuable intellectual property and process know-how from theft.
