     long bearing life is challenging at the high rotation speed necessary at a small overall diameter. Finally, at high
     speeds, precisely balancing the whole assembly to avoid vibrations that could lead to early mechanical failure is
     difficult.
+\item Tackling motor control algorithms for IHSMs and developing tamper sensors based on counter-electromotive force as
+    a defense-in-depth measure.
+\item Integrating the IHSM hardware concept with software research on secure enclave and cryptographic coprocessors.
 \item Exploring IHSM applications beyond what we outlined in this thesis. For instance, one application of recent
     interests would be physically securing GPUs used for AI training. The background for such work could be either
     export control motivations, or a concern for security and privacy of user input, training data, or even trained
