<p>The invention relates to a method for personalizing a smart meter or smart meter gateway security module (100) by means of a first computer system (150), energy consumption-specific measurement data elements being detectible by means of the smart meter (142; 144; 146; 148), the security module (100) having cryptographic functions for carrying out a cryptographically encoded communication of the measurement data elements received by the smart meter (142; 144; 146; 148) or the smart meter gateway (138) and a second computer system (166) of a utility company and/or operator of a measuring system, the method comprising the steps of: making the security module (100) available; generating an asymmetrical cryptographic pair of keys by means of the first computer system and storing the pair of keys in the security module (100); signing the public key of the pair of keys to obtain a certificate and storing the certificate in the security module (100) and/or in a public directory server (610), the signing being carried out by the first computer system (150), and the security module (100) being designed such that once the pair of keys is stored, an initial communication access to the smart meter (142; 144; 146; 148) and/or to the smart meter gateway (138) is only enabled for the first computer system (150), the initial communication access by the first computer system (150) enabling a release of the security module (100) for communication with the second computer system (166).</p> |
