[Verse 1] Traditional locks are crumbling fast When quantum bits come rushing past RSA keys that seemed so strong Won't protect us for very long Shor's algorithm breaks the chain Classical crypto feels the strain [Chorus] Lattice shields and hash-based towers Guard against quantum powers Code-based schemes and signature trees New foundations, quantum-resistant keys When qubits rise to crack the old These methods keep our secrets bold [Verse 2] Lattice problems twist and wind Mathematical knots that bind Shortest vectors hard to find Even when quantum's designed Grid-based puzzles lock the door Stronger than what came before [Chorus] Lattice shields and hash-based towers Guard against quantum powers Code-based schemes and signature trees New foundations, quantum-resistant keys When qubits rise to crack the old These methods keep our secrets bold [Bridge] Hash functions stack like building blocks One-way streets with quantum locks Merkle signatures branch and grow Binary trees in perfect rows Code-based cryptography hides In error patterns quantum can't divide [Verse 3] Multivariate equations dance Polynomial systems take their stance Isogenies between the curves Elliptic paths that quantum swerves NIST standards pave the way For post-quantum's brighter day [Chorus] Lattice shields and hash-based towers Guard against quantum powers Code-based schemes and signature trees New foundations, quantum-resistant keys When qubits rise to crack the old These methods keep our secrets bold [Outro] Tomorrow's threats need today's defense Post-quantum crypto makes more sense Future-proof our digital world Let these algorithms be unfurled
