COMPUTER FUNDAMENTALS

Detailed explanation-1: -Hardware encryption means having the encryption work at the device level. Here, a dedicated processor is physically located in the drive to encrypt the data. The only tasks this processor has to perform are encryption and authentication. Usually, it uses a random number generator for encryption key generation.

Detailed explanation-2: -Unlike software-based encryption, which uses passwords as encryption keys, hardware encryption devices generate encryption and decryption keys so only authorized users can access classified information.

Detailed explanation-3: -Modern cryptographic algorithms can be implemented using dedicated cryptographic hardware or software running on general-purpose hardware. For various reasons, dedicated cryptographic hardware provides a better solution for most applications.

Detailed explanation-4: -Advantages. Implementing cryptography in hardware means that part of the processor is dedicated to the task. This can lead to a large increase in speed.
