[Verse 1] When quantum computers arrive at our gate Classical crypto will crumble to fate But hidden in math lies a fortress so strong Error-correcting codes singing their song Hamming discovered the patterns that heal Broken transmissions made perfectly real Now cryptographers borrow this medical art To keep secret messages safe from the start [Chorus] HQC stands guard with quasi-cyclic might Syndrome decoding keeps hackers from sight Parity matrices weaving their spell Even quantum machines cannot break them well Code-based crypto, our post-quantum shield When other defenses are forced to yield [Verse 2] Take your plaintext and wrap it in noise Random errors become your decoys Only holders of secret generator keys Can strip away chaos with elegant ease The syndrome reveals just a glimpse of the flaw Not enough data for hackers to draw Conclusions about what the message contains While polynomial structures forge unbreakable chains [Chorus] HQC stands guard with quasi-cyclic might Syndrome decoding keeps hackers from sight Parity matrices weaving their spell Even quantum machines cannot break them well Code-based crypto, our post-quantum shield When other defenses are forced to yield [Bridge] Circular shifting makes storage compact Structured yet random, that's HQC's pact Decryption finds errors by Gaussian elimination Encryption adds them through random mutation The hardness assumption that keeps us secure No algorithm can syndrome patterns endure [Verse 3] NIST evaluates candidates today Searching for schemes that won't fade away When Shor's algorithm breaks RSA's spine Code-based systems will still hold the line Implementation demands careful finesse Key sizes large but performance's success The quantum apocalypse looms ever near But mathematics gives nothing to fear [Chorus] HQC stands guard with quasi-cyclic might Syndrome decoding keeps hackers from sight Parity matrices weaving their spell Even quantum machines cannot break them well Code-based crypto, our post-quantum shield When other defenses are forced to yield [Outro] From Hamming's wisdom to HQC's grace Error correction claims crypto's new space
