Smart-Meter Aggregation

Noise-based Privacy-Preserving Aggregation Scheme for Smart Grid AMI Networks with Hardware Acceleration

First author · 4th Intl. Conf. on AI, Blockchain and IoT · Accepted 2026

Meters are paired so their added noise cancels exactly at the aggregator: the utility reads a true sum while no individual reading is recoverable from the stream. The noise layer is written in RTL and runs on a Nexys A7-100T at 100 MHz as a pipelined multiply-accumulate datapath mapped onto the FPGA’s DSP slices, which is the structure a filter or a correlator is built from.
