Méthodes publiques

Méthode	Description
GenerateCommitment ( int numShares, BigZp coeffs, System.Numerics.BigInteger prime, MG &witnesses, PolyCommit polyCommit ) : MG
Recombine ( IList sharedSecrets, int polyDeg, System.Numerics.BigInteger prime ) : BigZp
Recombine ( IList sharedSecrets, int polyDeg, System.Numerics.BigInteger prime, bool usePrimitiveRecombine ) : BigZp	Recombines (interpolate) the secret from secret shares.
Share ( BigZp secret, int numPlayers, int polyDeg ) : IList	Calculates the shares of a secret with polynomial of degree t and numPlayers players.
Share ( BigZp secret, int numPlayers, int polyDeg, IList &coeffs ) : IList	Calculates the shares of a secret with polynomial of degree t and numPlayers players. The method also returns the array of coefficients of the polynomial.
