Question

Which of the following best describes the reason PQC preparation is important?

Options

  • ATo protect data against decryption due to increases in computational resource availability
  • BTo have larger key lengths available through key stretching

Explanation

Post-quantum cryptography (PQC) is about ensuring that encrypted data remains secure even when attackers have access to quantum computers, vastly more powerful computational resources than today’s systems. Without PQC algorithms, future quantum capabilities could decrypt today’s protected data, so preparing now safeguards information against that upcoming
