Queryable Encryption

“

- [Instructor] With client-side field level encryption, you can keep your data encrypted while it is in use, from the moment it leaves the client until it reaches the client again. However, there are two trade-offs. Due to the deterministic nature of the encryption used in CSFLE, your encrypted data is potentially subject to frequency leakage, and you can only perform equality queries. If you are using MongoDB Enterprise 7.0 or above, There is a new feature called queryable encryption, which provides an alternative to CSFLE, that uses fully randomized encryption rather than the deterministic encryption that CSFLE uses. Using randomized encryption means the encryption mechanism is safe to frequency leakage, so no one can analyze the encrypted content based on the frequency of specific tokens appearing. As of April 2024, the MongoDB documentation states that the feature supports equality searches, with additional query types such as range, prefix, suffix, and substring planned for…
