ISA/IEC 62443 Cybersecurity Fundamentals Specialist — Question 74

What is a feature of an asymmetric key?

Answer options

• A. Uses a continuous stream
• B. Uses different keys
• C. Shares the same key
• D. Has lower network overhead

Correct answer: B

Explanation

The correct answer is B, as asymmetric key encryption relies on a pair of keys: a public key and a private key, which are different from each other. Options A, C, and D are incorrect because they do not accurately describe the nature of asymmetric keys; A refers to a streaming method, C suggests a shared key which contradicts the definition of asymmetric encryption, and D doesn't relate to key characteristics.
