Industry 4.0 is a new trend in development of production technology. Industry 4.0 connects all computers in a production to the network. This poses new security issues to the production. Industry 4.0 scenarios are different from traditional enterprise networks and therefor can existing solution not be used to fix the security issues. The first step of a secure network is to implement access control. Because of the large volume of device, the access control for Industry 4.0 must be highly automated.
This project designs an identity management system based on blockchain and an automatic authentication protocol based on asymmetric cryptography. The designed system is not implemented.
The evaluation of the design has showed it is possible to make a blockchain based identity management system. This system offers a highly automated solution for identity management which is resilient against tampering and misuse.
The automated authentication protocol can use the identity management system and offer authentication with TLS without involvement of PKI.
The design in this project offer a solution to access control in Industry 4.0 which is deemed secure and automated.
