Final answer:
The correct answer is B. A structured approach to the error guessing technique. Fault attack is a methodical approach to testing that aims to expose faults, defects, and failures in a system.
Step-by-step explanation:
The correct answer is B. A structured approach to the error guessing technique. Fault attack is a methodical approach to testing that aims to expose faults, defects, and failures in a system. It involves creating a list of possible mistakes or errors and designing tests that will trigger those failures. This approach is commonly used in the field of cybersecurity to identify vulnerabilities in cryptographic systems. For example, in a fault attack on a cryptographic algorithm, the tester might deliberately manipulate inputs to generate faulty outputs and then analyze the system's response. This can help uncover weaknesses in the algorithm and potentially be used to exploit the system.
