Abstract: A method for detecting data manipulation of a field device is disclosed, said data being sent in the form of data packets using a communication channel. The field device is part of a secure sub-network. The sub-network includes the field device or an edge device and the field device. In a first step, a device key pair having a private device key and a public device key is generated using an asymmetric cryptosystem, where the private device key is stored in a signing sub-network device. In a second step, the signing sub-network device generates, for a group of data packets comprising data packets, a digital data signature using the private device key and transmits said digital data signature and the data packets to the receiving device. In a third step, the receiving device verifies the data packets using the associated data signature and the public device key.

Abstract: A field device of measuring- and automation technology, which field device meets requirements for operation in explosion-endangered environments. Safe operation of the field device in explosion-endangered environments is assured by a pluggable connector coupling for electrical coupling of different field device components. An essential feature of the pluggable connector coupling is a sealing element for spatial and gas-tight sealing of a contact region of contacting elements of the pluggable connector coupling from a free volume remaining in the pluggable connector coupling.
