Automated Construction of Security Integrity Wrappers for Industry 4.0 Applications

Industry 4.0 (I4.0) refers to the trend towards automation and data exchange in manufacturing technologies and processes which include cyber-physical systems, where the internet of things connect with each other and the environment via networking. This new connectivity opens systems to attacks, by, e.g., injecting or tampering with messages. The solution supported by standards such as OPC-UA is to sign and/or encrypt messages. However, given the limited resources of devices, instead of applying crypto algorithms to all messages in the network, it is better to focus on the messages that if tampered with or injected, could lead to undesired configurations.
