Quantum Secure Semiconductor is semiconductor devices and chips implementing quantum-safe cryptographic algorithms and quantum key distribution, protecting against future quantum computer threats — prepare for quantum era. Quantum Computing Threat quantum computers (if built) could break RSA, ECC. Harvest-now-decrypt-later attacks. Post-Quantum Cryptography lattice-based, hash-based, code-based algorithms thought secure against quantum computers. NIST standardizing. Implementation Hardware cryptographic operations require silicon. Efficient implementation critical. Lattice-Based CRYSTALS-Kyber (key agreement), CRYSTALS-Dilithium (signing). Semiconductor implementations exist. Hash-Based Merkle trees for signing. Stateful. Specialized hardware improves efficiency. Code-Based McEliece. Matrix operations. Semiconductor Acceleration crypto accelerators speed public-key operations. Dedicated hardware vs. software. Random Number Generation quantum RNGs (true random) vs. deterministic (pseudo-random). NIST recommendations. Key Storage cryptographic keys stored securely in non-volatile memory. Tamper protection. Quantum Key Distribution (QKD) BB84 protocol: quantum channel transmits keys securely. Detector required. Single-Photon Detectors avalanche photodiodes (APD) detect single photons. Specialized component. Integrated Photonics QKD potentially integrated on silicon photonics. Hybrid Classical-Quantum classical pre-shared key + quantum-verified session keys. Standardization NIST Post-Quantum Cryptography Standardization Project (round 3). Federal agencies adopting. Key Size post-quantum keys larger (2-4 KB typical). Bigger impact on memory, communication. Performance hardware acceleration enables real-time encryption/decryption. Compatibility existing systems modernized. Gradual migration. Supply Chain Security cryptographic hardware certified, validated. Trust in semiconductor source. Side-Channel Protection constant-time implementations resist timing attacks. Quantum-Safe Semiconductors essential for future cryptographic security.
