Once this subset of valid tokens is determined, Lagrange interpolation formula is executed to test each remaining token one at a time to identify whether it is an invalid token or not.
When the number of the signature shares got by any one participant or signature receiver reaches 2t + 1, he can compute the signature s according to the interpolation formula. Thus the signature (r, s) of the message m is got.
In [21, Section 1.5], Phillips has studied two new interpolation formulas on q-integers.
3 Secret Reconstruction Algorithm: In the secret reconstruction algorithm, any authorized subset of n participants with order has 4, S can be obtained using Lagrange's interpolation formula as in equations (2, 3) to reconstruct the polynomial f (x), and then find f (16) = S.
Using the Lagrange interpolation formula through five points, [V.sup.I.sub.[tau]i] and [V.sup.I.sub.ni] are calculated.
These formulas are independent of the true value of the spectrum, and then the interpolation formulas are obtained by Fourier series developments.
Computational procedures for the two types of data are generally different because interpolation formulas are often necessary when dealing with frequency distributions.
