Ringtail (Boschini et al., ePrint 2024/1113) is third-party prior art; Lux's Corona (Ring-LWE = Module-LWE rank-1) builds on it; Pulsar is Module-LWE rank-k. Retired the conflated boschini2024corona/corona2024/coronago/... bib keys to the single canonical ringtail/corona/pulsar/magnetar keys, rewrote \cite + \bibitem by context, and fixed 'Pulsar (Ring-LWE)' mislabels (Corona where corona.metal/ single-ring/Ringtail-derived; Pulsar where Module-LWE rank-k/ML-DSA). Cryptographer-led.

LSS integrates with Corona~\cite{corona} lattice-based threshold signatures for post-quantum security. Corona uses Learning With Errors (LWE) to provide threshold signatures secure against quantum computers:
|
|
|
|
\begin{itemize}[nosep]
|
|
\item \textbf{128-bit security}: $n = 512, q = 2^{32}$, signature $\sim$4KB
|
|
\item \textbf{192-bit security}: $n = 768, q = 2^{48}$, signature $\sim$6KB
|
|
\item \textbf{256-bit security}: $n = 1024, q = 2^{64}$, signature $\sim$8KB
|
|
\end{itemize}
|
|
|
|
The hybrid deployment uses classical (FROST/CMP) for day-to-day signing and Corona for finality certificates (via Quasar consensus~\cite{quasar}), ensuring both current efficiency and quantum-future safety.
