FrozenTRU: Cold Boot Attacks on NTRU-Based Hash-and-Sign Signatures

This paper investigates cold boot attacks against NTRU-based signature scheme Falcon and its ancestor, the signature scheme of Ducas–Lyubashevsky–Prest (DLP), and proposes countermeasures with negligible computational cost that significantly reduce the memory footprint of signing keys for Falcon and DLP, and at the sam...
