What is the key objective of homomorphic encryption? a. To encrypt memory only b. To enable VPN connections c. To allow computations on encrypted data without decrypting it d. To protect file systems

The key objective of homomorphic encryption is **c. To allow computations on encrypted data without decrypting it**. This technique enables operations to be performed on ciphertexts, generating an encrypted result that, when decrypted, matches the result of operations performed on the plaintext.
