Claim Text:
1. A method for communicating energy consumption-specific measurement data elements recorded by a smart meter from a smart meter device to a first computer system of a utility company and/or metering point operator, wherein the device has a security module, wherein the security module comprises a unique identifier and serves as the sole communication interface between the device and the first computer system, wherein the device has configuration data necessary for its operation, wherein the device is assigned a statement of those measurement data elements and/or configuration data for which the first computer system has a read access authorization, wherein a first part of the statement is stored in a memory area of the device, and wherein the method comprises: initializing the smart meter device; establishing a first communication channel between the first computer system and the security module; mutually authenticating the computer system and the security module, wherein the authentication takes place with the aid of a first certificate of the security module and with the aid of a second certificate of the first computer system; and after successful mutual authentication, transmitting at least a portion of the measurement data elements and/or configuration data specified in the statement to the first computer system, via the security module, by a secure transmission; where initializing the smart meter device comprises: establishing a second communication channel between the first computer system and a second computer system, wherein the first computer system and the second computer system are assigned to a set of computer systems connected via a network; authenticating the first computer system with respect to the second computer system; after successful authentication of the first computer system with respect to the second computer system, receiving data and the unique identifier of the security module from the first computer system, via a secure transmission, by the second computer system; assigning the unique identifier to the associated security module by the second computer system; establishing a third communication channel between the second computer system and the security module; authenticating the second computer system with respect to the security module, wherein the initialization serves to enable a communication of the security module with the first computer system, wherein, prior to the initialization of the memory area, a successful authentication with respect to the security module is possible only for the second computer system of the set of computer systems; and after successful authentication of the second computer system with respect to the security module, receiving of data from the second computer system by the security module through a secure transmission and storing the data in the memory area in order to initialize the memory area, wherein the communication between the first computer system and the security module while bypassing the second computer system is enabled only as a result of the stored data, wherein the stored data comprise the first part of the statement and an energy recording application, wherein the second computer system is a computer system of a trustworthy instance, wherein the initialization is triggered by the transmission of the identifier of the security module to the first computer system.
