WebThe deterministic encryption algorithm ensures that a given input value always encrypts to the same output value each time the algorithm is executed. While deterministic encryption provides greater support for read operations, encrypted data with low cardinality is susceptible to frequency analysis recovery. A deterministic encryption scheme (as opposed to a probabilistic encryption scheme) is a cryptosystem which always produces the same ciphertext for a given plaintext and key, even over separate executions of the encryption algorithm.
