CAS-005 · Question #412
Which of the following most likely explains the reason a security engineer replaced ECC with a lattice-based cryptographic technique?
The correct answer is D. It is currently considered a robust PQC technique. Lattice-based schemes, such as Learning With Errors (LWE) or Ring-LWE, are among the leading candidates in NIST’s post-quantum cryptography standardization process because their underlying hard problems resist known quantum-algorithm speedups. Replacing ECC with a lattice-based…
Question

Explanation
Lattice-based schemes, such as Learning With Errors (LWE) or Ring-LWE, are among the leading candidates in NIST’s post-quantum cryptography standardization process because their underlying hard problems resist known quantum-algorithm speedups. Replacing ECC with a lattice-based algorithm directly addresses the threat posed by future quantum computers, making it the preferred choice for long-term cryptographic agility.
