Question22Max. score: 1.00Which of the following is true?Keys must be unpredictable (large and random).Keys must be predictable so that systems can implement them.

To answer the question, we need to determine which statement is true: "Keys must be unpredictable (large and random)" or "Keys must be predictable so that systems can implement them."

1. Let's analyze the first statement: "Keys must be unpredictable (large and random)." This statement suggests that keys should be random and difficult to predict. This is often the case in cryptographic systems, where the security of the system relies on the unpredictability of the keys. Randomness helps to prevent unauthorized access and protect sensitive information.

2. Now let's consider the second statement: "Keys must be predictable so that systems can implement them." This statement suggests that keys should be predictable in order to facilitate the implementation of systems. However, this contradicts the principle of key security. If keys are predictable, it becomes easier for attackers to guess or deduce the keys, compromising the security of the system.

Based on this analysis, the correct statement is that "Keys must be unpredictable (large and random)." This ensures the security of the system by making it difficult for unauthorized individuals to guess or deduce the keys.
