Free Isaca Cybersecurity Audit Certificate Actual Exam Questions - Question 14 Discussion
computational power and offers more security per bit?
D. Also, Diffie-Hellman and DSS both rely on larger numbers, so they naturally take more processing power. Secret key cryptography (C) isn't even public key, so it doesn't fit here. ECC is designed to give strong security with smaller keys, making it faster and less demanding on resources. So it makes sense that D is the best pick for efficient public key cryptography.
Option D stands out because it offers strong security with smaller keys, unlike Diffie-Hellman or DSS which require larger keys and more processing power. That’s why it’s more efficient overall.
A imo, Diffie-Hellman uses bigger keys and slower math compared to ECC, so it’s less efficient. That makes D stand out for better security per bit with less computation.
It’s D because elliptic curve cryptography achieves the same security with much shorter keys compared to traditional methods, which means less computation and faster performance. That’s a big advantage over Diffie-Hellman or DSS.
B imo, Digital Signature Standard uses specific algorithms that can be quite efficient, but still not as optimized as ECC’s smaller key sizes and faster computations. ECC’s balance of security and speed is tough to beat here.
It’s definitely D. Secret key cryptography (C) isn’t even public key, so it’s out. Diffie-Hellman (A) and DSS (B) both rely on big numbers and more processing, while elliptic curves use smaller keys for the same security level. That’s why ECC stands out for less computational power with solid security per bit.
A imo, Diffie-Hellman is less efficient because it uses larger keys and more computation compared to elliptic curves. That’s why ECC (D) is the better pick for efficiency and security per bit.
D, it’s elliptic curves that really cut down the computational load in public key systems.
D imo, elliptic curve cryptography is known for using less computing power and giving stronger security compared to the classic Diffie-Hellman (A), which can be way slower and bulkier.
