Benchmarking PQC Algorithms: ML-KEM vs ML-DSA vs SPHINCS+ Performance

Performance comparison of NIST PQC algorithms: ML-KEM is fastest for key exchange, ML-DSA offers the best signature speed-to-size ratio, SPHINCS+ provides maximum security assurance with larger overhead.

Key Exchange: ML-KEM Wins

ML-KEM-768: KeyGen 0.1ms, Encapsulate 0.15ms, Decapsulate 0.15ms. Public key: 1,184 bytes. Ciphertext: 1,088 bytes. Comparable to ECDH in speed, slightly slower than X25519. The performance overhead of quantum-safe key exchange is negligible for practical applications.

Signatures: ML-DSA vs SPHINCS+

ML-DSA-65: Sign 2.7ms, Verify 1.0ms, Signature 3,309 bytes. SPHINCS+-128s: Sign 1,000ms, Verify 2.5ms, Signature 7,856 bytes. ML-DSA is 370x faster for signing and produces 2.4x smaller signatures. SPHINCS+ trades performance for conservative security assumptions.

BMIC’s Algorithm Selection

BMIC uses ML-KEM-768 for key exchange and ML-DSA-65 for signatures — the optimal combination of performance, security, and NIST compliance. The smart account architecture absorbs size overhead so users experience classical-like performance with quantum-grade security.

FAQ

Which algorithm should I choose? For most applications: ML-KEM for key exchange, ML-DSA for signatures. Use SPHINCS+ only when hash-function-only security is required and performance is not critical.

The Quantum Clock Is Ticking — Act Now

Every day you wait, more of your public keys are being harvested. Intelligence agencies are running Harvest Now, Decrypt Later operations right now. Your wallet’s ECDSA keys are being collected and stored for the day quantum computers can crack them. That day is approaching faster than anyone expected.

BMIC’s presale is live — but it won’t last forever. With 50 phases and a 20% price increase from first to final tier, every phase that passes means a higher entry price. A listing date or price is not announced \xe2\x80\x94 follow official BMIC channels for updates.

Don’t be the person who understood the quantum threat but didn’t act. The presale has already raised over $an undisclosed sum, reflecting growing interest from early supporters.
