An industrial automation system device includes: a secure communication processing unit for communicating securely with a further trusted industrial automation system device; and a pre-shared secret module including a pre-shared secret, the pre-shared secret including shared asymmetric key pair generation data. The secure communication processing unit: derives a shared asymmetric key pair including a shared secret key and a shared public key from the shared asymmetric key pair generation data, derives a shared certificate including the shared public key, signs the shared certificate with the derived shared secret key, and generates a device asymmetric key pair including a device secret key and a device public key.
