Which of the following allows computation and analysis of data within a ciphertext without knowledge of the plaintext?
Which of the following allows computation and analysis of data within a ciphertext without knowledge of the plaintext?
Homomorphic encryption allows computations and analysis to be performed on data within ciphertext without requiring knowledge of the plaintext. This type of encryption enables operations to be conducted directly on encrypted data, and the results of these operations remain encrypted. When the encrypted results are eventually decrypted, they match the outcome that would have been obtained if the operations had been performed on the plaintext. This property makes homomorphic encryption particularly valuable for applications where data privacy is paramount.
D Homomorphic encryption allows a company to perform statistical calculations on fields within the data while keeping the data set as a whole encrypted.
CompTIA Book - Homomorphic encryption is a form of encryption that is unique in that it allows computation on ciphertexts and generates an encrypted result that, when decrypted, matches the result of the operations as if they had been performed on the plaintext.

Homomorphic
D is the answer. refers to homomorphism in algebra: the encryption and decryption functions can be thought of as homomorphisms between plaintext and ciphertext spaces.
Homomorphic encryption
Homomorphic encryption allows computation and analysis of data within ciphertext without knowledge of the plaintext. This type of encryption enables operations to be performed on encrypted data without needing to decrypt it first, thereby maintaining data privacy and security throughout the computation process. The result of the computation, when decrypted, matches the result of the same operations performed on the plaintext.
The correct answer is: D. Homomorphic encryption Explanation: Homomorphic Encryption: Homomorphic encryption is a cryptographic technique that allows computations and analysis of data to be performed on encrypted data without decrypting it. This enables operations to be carried out on ciphertext, and the results are in encrypted form, which can then be decrypted to obtain the final result.
I agree with D
Just take a look at wiki https://en.wikipedia.org/wiki/Homomorphic_encryption :)

lol, I can't with some of you guys...FFS. How in the world are you telling people to go with D? For those who voted for D, please describe your updated security training awareness program. I can see your power point now...
