Problems solved by technology
It is known from the prior art that the private key corresponding to the public key is stored on the hardware security module of the network element and cannot be removed from the hardware components of the network element
This has the disadvantage, in particular, that the digital identity of the network unit is lost along with the hardware security module when the hardware component is replaced

Embodiment Construction
[0040] figure 1 A flow chart of the method according to the first aspect is shown schematically. figure 1 A method for the initial setup of the machine data communication network 10 is schematically shown. The machine data communication network 10 has a network element 12 . The network unit 12 has a first hardware component 14 . The first hardware component 14 has a hardware security module 16 . The network unit 12 has an identification device 18 separate from the hardware security module.
[0041] In a method of initially setting up a machine data communication network 10, a network unit 12 is provided with a first hardware component 14 and a digital identity DI. For the digital identity DI, the signature of the network unit 12 is generated for the communication partner 20 of the network unit 12 within the machine data communication network 10 on the basis of a first private key which is stored in the first hardware of the first hardware component 14 In the security modu...
