Which statement is true regarding key management?

The statement regarding key management that is true is that it includes the generation of a random number of keys. Key management is fundamentally about securely creating, storing, distributing, and managing cryptographic keys throughout their lifecycle. A key component of this process is key generation, which involves producing cryptographic keys that are often random to ensure security.

Using random numbers to create keys is essential because predictable keys can lead to vulnerabilities, allowing unauthorized access to encrypted data. Cryptographic algorithms rely on randomness to maintain the confidentiality and integrity of the data, preventing attackers from easily deciphering the keys.

While key management may involve the other aspects mentioned, such as managing keys within an encryption engine or being used in file-level encryption, the primary and crucial function is the generation of secure keys, which is why this statement stands out as true.
