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. Examples of deterministic encryption algorithms include RSA … See more Deterministic encryption can leak information to an eavesdropper, who may recognize known ciphertexts. For example, when an adversary learns that a given ciphertext corresponds to some interesting … See more To counter this problem, cryptographers proposed the notion of "randomized" or probabilistic encryption. Under these schemes, a given plaintext can encrypt to one of a very large set of possible ciphertexts, chosen randomly during the encryption process. … See more While deterministic encryption schemes can never be semantically secure, they have some advantages over probabilistic schemes. Database … See more Assuming that a deterministic encryption scheme is going to be used, it is important to understand what is the maximum level of security that can be guaranteed. A number of works have focused on this exact problem. The first work to rigorously define security for a … See more • Convergent encryption • Format-preserving encryption • Searchable symmetric encryption See more WebTo search for keyword w, the client just sends a deterministic encryption of w to the server. This encryption of the keyword, d w = E n c K 1 D ( w), will serve as the token. …
