Struct KkAeadPacket 

pub struct KkAeadPacket {
    pub aad: Vec<u8>,
    pub ciphertext: Vec<u8>,
    pub entropy_snapshot: EntropySnapshot,
    pub commitment: TemporalCommitment,
}

A KK-AEAD packet: ciphertext + authenticated associated data.

Contains:

• Associated data (AAD) - transmitted in the clear, authenticated
• The ciphertext (XOR of plaintext with per-symbol key stream)
• The entropy snapshot ε (the unrepeatable moment)
• Temporal commitment (binds ciphertext + AAD to the entropic moment)

The AAD is NOT encrypted but IS integrity-protected by the commitment. Any modification to the AAD or ciphertext will be detected on decode.

Fields

aad: Vec<u8>

Associated data, authenticated but not encrypted

ciphertext: Vec<u8>

The encoded bytes

entropy_snapshot: EntropySnapshot

The entropy snapshot

commitment: TemporalCommitment

Temporal commitment binding ciphertext + AAD to the entropic moment

Implementations

impl KkAeadPacket

pub fn to_bytes(&self) -> Vec<u8>

Format: [4-byte aad_len][aad][4-byte ct_len][ciphertext][48-byte snapshot][32-byte commitment]

pub fn from_bytes(data: &[u8]) -> Result<Self>

Deserialize from received bytes.

Trait Implementations

impl Clone for KkAeadPacket

fn clone(&self) -> KkAeadPacket

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
