Quantum computing threatens today’s encryption algorithms like RSA, DH, and ECC, which could be broken once a general-purpose quantum computer is built. Attacks such as “store-now, decrypt-later” pose risks to long-term data confidentiality. In response, NIST is developing post-quantum cryptography (PQC), with new algorithms like Kyber, Dilithium, Falcon, and SPHINCS+. Broadcom is preparing for Q-Day by tracking standards, supporting crypto agility, and updating its products to swap in quantum-resistant algorithms. Progress in quantum computing is accelerating, bringing urgent need for secure, future-proof encryption solutions.
