Abstract : pA (t,nbsp;n) threshold scheme is a method for sharing a secret amongnbsp;nnbsp;shareholders so that the collaboration of at leastnbsp;tnbsp;shareholders is required in order to reconstruct the shared secret. In this paper, we propose a (t,nbsp;n) secure sum multiparty computation protocol using multivariate polynomial secret sharing scheme. In this scheme, anynbsp;tnbsp;or more shareholders acting in collusion can reconstruct the secret, but a particular shareholder’s information is not revealed to other shareholders. This scheme can be applied for authenticating a selected single group ofnbsp;tparticipants securely without revealing their shares./p
