In this paper, we investigate the hardware implementation of SKINNY and Romulus. In Section 2, we explore the implementation of Romulus-M, the nonce misuse-resistant variant of Romulus. In Section 3, we explore the first-order masked implementations of the SKINNY SBox. While we focus on the SKINNY SBox, our results and observations apply to any SBox, as they represent underlying issues in the masking schemes.
