WebJul 21, 2024 · 8. As a high level concept, nondetermistic encryption is where the encryption function takes three inputs, the key k, the plaintext P and a random value R, generating a ciphertext C = E k ( P, R); the idea is that a) two different random values R gives completely different ciphertexts C, even if the plaintexts where the same (or … WebAug 31, 2024 · Any deterministic public-key encryption scheme is subject to a very simple attack: given a ciphertext, guess what the plaintext might be, and verify the guess by …

Hashing vs Encryption: what

WebBecause RSA encryption is a deterministic encryption algorithm (i.e., has no random component) an attacker can successfully launch a chosen plaintext attack against the cryptosystem, by encrypting likely plaintexts under the public key and test if they are equal to the ciphertext. A cryptosystem is called semantically secure if an attacker ...

Although we cannot achieve semantic security or indistinguishability for deterministic encryption due to lack of randomness in cipher text, there is an analysis ...

WebFor example, encryption schemes that encrypt only secret key material (e.g., key encapsulation or Key Wrap schemes) can be considered under an entropic security definition. A practical application of this result is the use of deterministic encryption algorithms for secure encryption of secret key material. In computer science, a deterministic algorithm is an algorithm that, given a particular input, will always produce the same output, with the underlying machine always passing through the same sequence of states. Deterministic algorithms are by far the most studied and familiar kind of algorithm, as well as one of the most practical, since they can be run on real machines efficiently. Formally, a deterministic algorithm computes a mathematical function; a function has a unique v…
