Q81 / 100
What is post-quantum cryptography (PQC)?
Correct! Well done.
Incorrect.
The correct answer is B) Cryptographic algorithms believed to be resistant to attacks by quantum computers, currently being standardized by NIST
B
Correct Answer
Cryptographic algorithms believed to be resistant to attacks by quantum computers, currently being standardized by NIST
Explanation
Shor's algorithm breaks RSA/ECC. Grover's algorithm halves symmetric key security. NIST PQC standards (2024): CRYSTALS-Kyber (KEM), CRYSTALS-Dilithium, FALCON, SPHINCS+ (signatures) — based on lattices and hash trees.
