Abstract
Proactive Secret Sharing (PSS) is a scheme that allows periodically generating
new set of shares from the old shares for the same secret.
Proactive secret sharing has
numerous applications to maintain data which is a long lived in scenarios where accessibi
lity
and confidentiality are vital. The Proactive secret sharing achieves both these goals by
dividing secret in group of participants and by periodically
updating the shares.(

In this paper a proactive secret sharing in dot product
of linearly independent
vectors is proposed. The proposed scheme periodically renews the existing shares without altering the original secret using orthogonal vectors. The comparative study shows that proposed scheme is less complex and more secure
