Leakage-resilient rekeying schemes aim to maintain cryptographic security in the presence of side-channel leakage by periodically refreshing ephemeral keys before sufficient information can be accumulated by an adversary. Fallen Sanctuary (LR4) is a recent higher-order leakage-resilient rekeying construction that achieves exponential security amplification with respect to the number of primitive encryption invocations and the number of traces required to compromise the physical security of the i
