Abstract
A method for transmitting consumption data by a meter to a meter data management system is described. The meter obtains (S301) consumption data, the data being obtained by metrology software. It generates (S302) a hashcode from a triplet comprising a serial number of the meter, a cyclic redundancy code calculated from the metrology software and a certificate number certifying that the meter is authorised to be used for invoicing consumption. It next encrypts (S304) the hashcode with a private key known solely to the meter, in order to obtain a signature. Finally, it transmits (S306), to the system managing said consumption data, a frame comprising an identifier of the meter, the consumption data obtained and the signature.
