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.
