Lyrics

[Verse 1]
When quantum computers threaten our codes
Traditional signatures hit dead-end roads
RSA and ECDSA won't survive the storm
We need hash-based schemes to weather and transform

SLH-DSA stands guard with mathematical might
Stateless signatures that quantum can't bite
Built on hash functions we trust and we know
One-time signatures in Merkle tree flow

[Chorus]
Hash once, sign once, that's the golden rule
Merkle trees and WOTS keep our crypto cool
SLH-DSA, post-quantum and strong
When the quantum age comes, we'll sing this song
Stateless and secure, though the signatures grow
Trade size for safety, that's the way we go

[Verse 2]
SPHINCS-Plus evolved to SLH standardized
FIPS 205 got it recognized
WOTS-Plus handles each one-time key
Winternitz parameters set the degree

Higher W means smaller signatures made
But verification time is the price that's paid
Security levels one-two-eight to two-five-six
Choose your parameters, pick your perfect mix

[Chorus]
Hash once, sign once, that's the golden rule
Merkle trees and WOTS keep our crypto cool
SLH-DSA, post-quantum and strong
When the quantum age comes, we'll sing this song
Stateless and secure, though the signatures grow
Trade size for safety, that's the way we go

[Bridge]
No state to manage, no keys to track
Sign any message, there's no looking back
Tree height determines how many you'll sign
Hyper-trees layer to make it divine

SHAKE and SHA give us collision resistance
Pseudorandom functions provide our assistance
Few-time signatures in the FORS design
Multi-target attacks get left behind

[Verse 3]
Signature sizes reach kilobytes range
Bandwidth and storage see significant change
But quantum resistance is worth every byte
When Shor's algorithm puts classical crypto in flight

Fast verification keeps the system alive
Though signing is slower, security will thrive
Hash-based foundations won't crumble or fall
SLH-DSA protects us all

[Chorus]
Hash once, sign once, that's the golden rule
Merkle trees and WOTS keep our crypto cool
SLH-DSA, post-quantum and strong
When the quantum age comes, we'll sing this song
Stateless and secure, though the signatures grow
Trade size for safety, that's the way we go

[Outro]
When quantum dawn breaks on our digital shore
Hash-based signatures will open the door
SLH-DSA standing firm and true
Post-quantum protection for me and you
