Final answer:
Deterministic Encryption and Randomized Encryption are two techniques used in Always Encrypted for data protection. Randomized Encryption is considered more secure as it produces unique encrypted values for each input.
Step-by-step explanation:
Both Deterministic Encryption and Randomized Encryption are techniques used in Always Encrypted (AE) for protecting data. Deterministic Encryption produces the same encrypted value for the same input, which can lead to semantic relationships between the encrypted values. On the other hand, Randomized Encryption generates a unique encrypted value for each input, making it more secure as it doesn't reveal patterns in the data.
Dynamic Encryption and Static Encryption are not options in Always Encrypted. They are not directly related to the encryption techniques provided by AE.
