Please share your thoughts:

 

Which of the following technologies allows CSPs to add encryption across multiple data storages?
A. Symmetric encryption
B. Homomorphic encryption
C. Data dispersion
D. Bit splitting

 

 

The technology that allows CSPs (Cloud Service Providers) to add encryption across multiple data storages is:

B. Homomorphic encryption

Explanation:

Homomorphic encryption is a form of encryption that allows computation on ciphertexts, generating an encrypted result that, when decrypted, matches the result of the operations as if they had been performed on the plaintext. This means that data can remain encrypted across multiple storage systems, and operations can be performed on it without needing to decrypt it first, which is especially useful in cloud environments.

A. Symmetric encryption involves the use of a single key for both encryption and decryption. While it provides encryption, it doesn't specifically allow for operations across multiple data storages without decryption.

C. Data dispersion is a method used to distribute and store data across multiple locations or storage mediums. While it can enhance data security and availability, it doesn't inherently provide encryption across multiple data storages.

D. Bit splitting is a method of breaking data into multiple pieces and storing them separately. While it can be a technique for enhancing security, it doesn't provide encryption in the same way that homomorphic encryption does.

Therefore, the most appropriate technology for adding encryption across multiple data storages in a way that allows for operations on the encrypted data is Option B, Homomorphic encryption.
