Struct zebra_chain::sapling::keys::TransmissionKey
source · pub struct TransmissionKey(_);Expand description
A (diversified) TransmissionKey
In Sapling, secrets need to be transmitted to a recipient of funds in order for them to be later spent. To transmit these secrets securely to a recipient without requiring an out-of-band communication channel, the diversified transmission key is used to encrypt them.
Derived by multiplying a JubJub point derived from a Diversifier by the IncomingViewingKey scalar.
The diversified TransmissionKey is denoted pk_d in the specification.
Note that it can be the identity point, since its type is
KA^{Sapling}.PublicPrimeSubgroup which in turn is J^{(r)}.
