We explore whether the structural secret (layers and hyper-parameters) of a victim DNN model can be inferred by a remote attacker who shares the same FPGA board.
We show by implementing on-chip RO-based power monitors, the power consumption of the victim DNN can be sampled at high resolution, which guarantees all layers and hyper-parameters can be reconstructed at high accuracy.

We exploit the GPU side-channel based on context-switching penalties.
This side-channel allows us to extract the fine-grained structural secret of a DNN model, including its layer composition and hyper-parameters.
Leveraging this side-channel, we developed an attack prototype named MosConS, which applies LSTM-based inference models to identify the structural secret.

About me
|
 |
In my free time, I love to ride road bikes. In the summer of 2018, I cycled around Taiwan Province with my friends.
I was a member of University of California Irvine Cycling Club and was the leader of Sichuan University Cycling Club.
Also, I like to capture the beautiful moments of our life stories with my wife, Jinrun.
