Struct SharedKeys 

Source 
pub struct SharedKeys<E: Scalar, G: GroupElement<E>> {
    pub alpha: GenericArray<u8, G::AlphaLen>,
    pub secrets: Vec<SharedSecret>,
    _d: PhantomData<(E, G)>,
}
Expand description

Structure containing shared keys for peers using the Sphinx algorithm.

Fields§

§alpha: GenericArray<u8, G::AlphaLen>§secrets: Vec<SharedSecret>§_d: PhantomData<(E, G)>

Implementations§

Source§

impl<E: Scalar, G: GroupElement<E>> SharedKeys<E, G>

Source

pub(crate) fn generate( peer_group_elements: Vec<(G, &GenericArray<u8, G::AlphaLen>)>, ) -> Result<SharedKeys<E, G>>

Generates shared secrets given the group element of the peers and their Alpha value encodings.

The order of the peer group elements is preserved for resulting shared keys.

Source

pub(crate) fn forward_transform( alpha: &GenericArray<u8, G::AlphaLen>, private_scalar: &E, public_element_alpha: &GenericArray<u8, G::AlphaLen>, ) -> Result<(GenericArray<u8, G::AlphaLen>, SharedSecret)>

Calculates the forward transformation given the local private key.

Efficiency note: the public_element_alpha is a precomputed group element Alpha encoding associated with the private_scalar.
