Homework Help: Questions and Answers: A cancer diagnostic clinic must transfer a large amount of data to a cloud vendor to migrate from its on-premises server. However, the amount of data would make the transfer over the internet take extensive time due to the limited bandwidth the clinic’s internet provides. Instead, it wants to ship an encrypted copy of the data to the vendor. What type of encryption would BEST fit the clinic’s needs?

a) Symmetric algorithm b) Cryptography c) Plaintext d) Asymmetric algorithm

Answer:

First, let’s understand the question: The clinic needs to transfer a large amount of data securely to a cloud vendor by shipping an encrypted copy of the data. This means the focus is on encryption and ensuring the data remains secure during the shipment.

Now, we need to determine which type of encryption is best suited for this situation.

Given Options: Step by Step Answering

a) Symmetric algorithm:

In symmetric encryption, the same key is used to both encrypt and decrypt the data. It is fast and ideal for encrypting large amounts of data. However, both the sender and receiver must have the same key, so secure key exchange must be arranged.

b) Cryptography

Cryptography is a broad term that encompasses both symmetric and asymmetric encryption methods. It’s not a specific type of encryption, but rather the study of secure communication. Therefore, this option is too general.

c) Plaintext

Plaintext refers to unencrypted data. This is not secure and does not involve encryption, so this option is inappropriate.

d) Asymmetric algorithm

Asymmetric encryption uses a public key for encryption and a private key for decryption. It’s more secure for small amounts of data or for securely exchanging keys, but it is slower than symmetric encryption for large datasets.

Final Answer:

Based on the above analysis, the correct answer is:

a) Symmetric algorithm

This option provides the necessary security while being efficient for large amounts of data. The clinic can use a symmetric algorithm to encrypt the data, then securely share the encryption key with the cloud vendor separately from the shipped data.
