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. WebAs with encryption in general, this involves a public key and a private key. When an initiator node v 0 wants to send a message to a receiver node v, it will use v’s public key to encrypt the message; then only v can decrypt it, using its private key.
