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 ... WebFeb 28, 2024 · When using randomized encryption: IV = Generate cryptographicaly random 128bits If there's deterministic encryption, the IV isn't randomly generated, but instead it's derived from the plaintext value using the following algorithm: When using deterministic encryption: IV = HMAC-SHA-256( iv_key, cell_data ) truncated to 128 bits. guy st john taylor
