METHOD FOR TRANSMITTING METERING DATA FROM SMART METER TO ADVANCED METERING INFRASTRUCTURE SERVER

摘要

In the present invention, disclosed is a method for transmitting encrypted metering data to an advanced metering infrastructure (AMI) server from a smart meter, to a data collection unit (DCU) which is an intermediate node, or transmitting the aggregate metering data without decoding, to the AMI server therefrom, in an AMI environment according to a smart grid.;COPYRIGHT KIPO 2014;[Reference numerals] (100i) Smart meter i; (200a) Data collection unit 1; (300) Advanced metering infrastructure server; (S300) Collect metering information (Mi); (S310) Generate a first ciphertext (Ci); (S320) Convert the first ciphertext (Ci) to a second ciphertext (ACi); (S330) Transmit the second ciphertext (ACi); (S340) Collect the second ciphertext; (S350) Generate a single ciphertext (P); (S360) Transmit the single ciphertext (P); (S370) Decode the single ciphertext (P); (S380) Separate the metering information; (S390) Determine that the smart meter i did not transmit the metering information (i) if Mi is 0
