NIST Selects HQC as Fifth Algorithm for Post-Quantum Encryption

Credit: J. Wang/NIST and Shutterstock Last year, NIST standardized a set of encryption algorithms that can keep data secure from a cyberattack by a future quantum computer. Now, NIST has selected a backup algorithm that can provide a second line of defense for the task of general encryption, which safeguards internet traffic and stored data alike. Encryption protects sensitive electronic information, including internet traffic and medical and financial records, as well as corporate and national security secrets. But a sufficiently powerful quantum computer, if one is ever built, would be able to break that defense. NIST has been working for more than eight years on encryption algorithms that even a quantum computer cannot break. Last year, NIST published an encryption standard based on a quantum-resistant algorithm called ML-KEM. The new algorithm, called HQC, will serve as a backup defense in case quantum computers are someday able to crack ML-KEM. Both these algorithms are designe ... Read full article.
