Struct KkBoundPacket

Source

pub struct KkBoundPacket {
    pub ciphertext: Vec<u8>,
    pub entropy_snapshot: EntropySnapshot,
    pub proof: TemporalProof,
}

Expand description

A KK packet with a full temporal proof (challenge-response).

Unlike KkPacket, which carries a basic integrity MAC, this packet carries a TemporalProof providing:

Freshness: verifier-supplied nonce proves creation was after the challenge
Recency: epoch check bounds when the encoding actually happened
Ordering: prev_mac chains packets into a total order
Temporal MAC: the permutation structure itself varies with entropy

The receiver must supply the nonce they originally issued and the maximum acceptable clock drift.

Fields§

§ciphertext: Vec<u8>

The encoded bytes

§entropy_snapshot: EntropySnapshot

The entropy snapshot, the captured moment

§proof: TemporalProof

Temporal proof, freshness + recency + integrity + ordering
