Abstract
Data are sent from an internal data processing system of an Industrial plant to an external data processing system of the industrial plant by generating with an industrial edge device data packets from data related to an industrial machine, and generating therefrom signed data packets signed with a first digital signature. While the signed data packet are read, a user-defined data filter is applied, which either passes or rejects the signed data packets. The data packets that passed the user-defined data filter are then sent to the external data processing system. In addition, double-signed data packets are produced by signing the signed data packets that pass the user-defined data filter with a second digital signature.
