FIPS 204 — ML-DSA-65 — Post-Quantum Cryptography

ML-DSA based Q-Signer

FIPS 204 ML-DSA-65 compliant Post-Quantum Digital Signature — free for everyone

ML-DSA based Q-Signer uses Hytak Random Number (True Random Number Generator / TRNG) for y and s, SHA1024 for challenge c, matrix A (2×2 demo) for w1 = HighBits(Ay, 261,888), and z = y + c·s (c = SampleInBall(c~), c~ = SHA256(m‖w1)) for quantum-safe digital signature per FIPS 204.

w1 = HighBits(Ay, 2γ)
z = y + c·s

A = 2×2 demo matrix of polynomials mod q

y = Hytak True RNG (TRNG) ±2¹⁷

w1 = HighBits(Ay, 523,776)

c~ = SHA256(m‖w1) | c = SampleInBall(c~)

s = Hytak True RNG (TRNG) — secret key

z = Digital Signature output

How it works — FIPS 204 ML-DSA-65

Upload signature image or type your name — used as message for SHA1024

SHA1024 = SHA256 × 4 chain → 256 hex digits → used for position selection in SampleInBall

Matrix A (2×2 demo) generated — 4 polynomials of degree 256, coefficients mod q = 8,380,417

y vector (4 polynomials) generated by Hytak TRNG — coefficients in −2¹⁷ ~ +2¹⁷ (±131,072)

w1 = HighBits(Ay, 2γ) — polynomial matrix-vector multiplication mod q then HighBits decomposition with 2γ = 261,888

c~ = SHA256(m ‖ w1) — 32 bytes = 256 bits for sign determination | c = SampleInBall(c~) — sparse polynomial tau=49

s vector (4 polynomials) generated by Hytak TRNG → 3-step transformation → coefficients in {−2, −1, 0, +1}

z = y + c·s (c = SampleInBall(c~)) → quantum-safe digital signature! ✅ FIPS 204 compliant!
