Abstract: A method for logging a user into a device for a power generation plant, using a service gateway, wherein an access authorization of the user for the device is stored on the service gateway, is disclosed. The method includes authenticating the user on the service gateway, sending a device access request using an access device from the user to the service gateway specifying an identifier of the device for the power generation plant, and comparing a device secret stored on the service gateway with a copy of the device secret generated using the device secret and stored on the device, via an SRP protocol.

Abstract: A method for defining authentication data of a user at an energy conversion device connected to a grid and a source via a network connection includes receiving at the energy conversion device, via the network connection, a request from the user to newly assign authentication data, receiving at the energy conversion device desired authentication data of the user via the network connection, and storing the desired authentication data in the energy conversion device for an authentication of the user in the event of subsequent attempts to access the energy conversion device, when the energy conversion device is disconnected from the connected grid within a first predefined time window after receiving the request.
