QuestionQ111

Governance, Risk, and Compliance

Which of the following most accurately explains why implementing PQC is important?

  • A To protect data against decryption due to increases in computational resource availability
  • B To have larger key lengths available through key stretching
  • C To improve encryption performance and speed using lightweight cryptography
  • D To leverage asymmetric encryption for large amounts of data
Explanation

Post-quantum cryptography protects information against future decryption as increased computational capability, particularly quantum computing, threatens many currently deployed public-key cryptosystems. It helps mitigate the risk that encrypted data is collected today and decrypted later.
