Randomized encryption generates a different encrypted value for the same plaintext each time. So if we would encrypt a boolean column holding only truevalues, we would get a different encrypted payload for each of them. This encryption method is more secure then deterministic, but … See more When it comes to securing a SQL server there are severeal things we need to think of. One of this things is the protection of our data in transit and/or at rest by using encryption. … See more I think that the deterministic encryption type is somewhat similar to the way hashing algorithms work. This method always generates the same encrypted value for any given … See more WebTo search for keyword w, the client just sends a deterministic encryption of w to the server.

Webencryption (HE) to keep the noise growth slow. If it is randomized following a subgaussian distribution, it is called subgaussian (gadget) decomposition which guarantees that we can bound the noise contained in ciphertexts by its variance. This gives tighter and cleaner noise bound in average case, instead of the use of its norm. Webalgorithm is deterministic.
