Struct NsAvidmGf2Scheme 

pub struct NsAvidmGf2Scheme;

Dummy struct for namespaced AvidmGf2 scheme

Implementations

impl NsAvidmGf2Scheme

pub fn setup( recovery_threshold: usize, total_weights: usize, ) -> Result<NsAvidmGf2Param, VidError>

Setup an instance for AVID-M scheme

pub fn commit( param: &NsAvidmGf2Param, payload: &[u8], ns_table: impl IntoIterator<Item = Range<usize>>, ) -> Result<(NsAvidmGf2Commit, NsAvidmGf2Common), VidError>

Commit to a payload given namespace table. WARN: it assumes that the namespace table is well formed, i.e. ranges are non-overlapping and cover the whole payload.

pub fn ns_disperse( param: &NsAvidmGf2Param, distribution: &[u32], payload: &[u8], ns_table: impl IntoIterator<Item = Range<usize>>, ) -> Result<(NsAvidmGf2Commit, NsAvidmGf2Common, Vec<NsAvidmGf2Share>), VidError>

Disperse a payload according to a distribution table and a namespace table. WARN: it assumes that the namespace table is well formed, i.e. ranges are non-overlapping and cover the whole payload.

pub fn verify_share( commit: &NsAvidmGf2Commit, common: &NsAvidmGf2Common, share: &NsAvidmGf2Share, ) -> Result<Result<(), ()>, VidError>

Verify a namespaced share

pub fn recover( common: &NsAvidmGf2Common, shares: &[NsAvidmGf2Share], ) -> Result<Vec<u8>, VidError>

Recover the entire payload from enough share

pub fn ns_recover( common: &NsAvidmGf2Common, ns_index: usize, shares: &[NsAvidmGf2Share], ) -> Result<Vec<u8>, VidError>

Recover the payload for a given namespace. Given namespace ID should be valid for all shares, i.e. ns_commits and content have at least ns_index elements for all shares.

impl NsAvidmGf2Scheme

pub fn namespace_proof( common: &NsAvidmGf2Common, payload: &[u8], ns_index: usize, ) -> Result<NsProof, VidError>

Generate a proof of inclusion for a namespace payload.

pub fn verify_namespace_proof( commit: &NsAvidmGf2Commit, common: &NsAvidmGf2Common, proof: &NsProof, ) -> Result<Result<(), ()>, VidError>

Verify a namespace proof against a namespaced VID commitment.
