A financial institution would like to store its customer data in the cloud but still allow the data to be accessed and manipulated while encrypted. Doing so would prevent the cloud service provider from being able to decipher the data due to its sensitivity. The financial institution Is not concerned about computational overheads and slow speeds. Which of the following cryptographic techniques would best meet the requirement?

Suggested answer: C

Explanation:

Homomorphic encryption is a cryptographic technique that allows data to be stored, accessed and manipulated while encrypted. Homomorphic encryption enables computations to be performed on ciphertexts, generating an encrypted result that, when decrypted, matches the result of the operations as if they had been performed on the plaintext. Homomorphic encryption can prevent the cloud service provider from being able to decipher the data due to its sensitivity, as the data remains encrypted at all times. Homomorphic encryption is not concerned about computational overheads and slow speeds, as it trades off performance for security and privacy.
