Short Paper: New Multistage Secrete Sharing Scheme Based On the Factorization Problem

摘要

An efficient multistage (t,n) secret sharing scheme is proposed. The scheme allows a group of users to share multiple secrets, and only one secret share needs to be kept by each user. Knowing the exposed secrets will not affect the security of the other secrets not yet revealed. Moreover, only one public value is needed in the proposed scheme.
