Problem definition

Phoenix Contact aims to provide standardised cybersecurity in products and industrial solutions to enable future-proof operation of machines, plants and infrastructures. In order to ensure that products and solutions are protected against professional cyber attackers, the requirements of the IEC 62443 standard, 
which is essential for the manufacturing industry, must be met.

To prove the authenticity of hardware and software products Phoenix Contact relies on the use of high-quality electronic certificates and digital signatures. These certificates are used technically for secure device
identity in accordance with IEEE802.1AR and secure firmware updates. To generate the electronic certificates, Phoenix Contact therefore planned to set up a company-wide public key infrastructure that could permanently fulfil the required high level of protection. One of the most important requirements in this project was to seamlessly integrate device registration into an industrial production process.

Building a scalable and secure PKI for device identities and infrastructure for signatures of software and firmware is a challenging task. This made it all the more important to find suitable technical products and a suitable partner for the implementation project and ongoing support.
