A (t, n) secret sharing scheme that divides a secret into n shares in such a way that any t or more than t shares can reconstruct the secret; but fewer than t shares cannot reconstruct the secret. A share renewal protocol is to protect a secret in long-lived system by distributing it to a group of n participants and refreshing their shares periodically in this fixed group. In this paper we propose a share renewal protocol without the presence of a trusted party. Shareholders renew their shares among themselves using old shares without disclosing their shares at any stage of the protocol and able to reconstruct the secret without changing it. The protocol is robust and maintain privacy of shares.
