New Multistage Secret Sharing Scheme Based on the Factorization Problem
Narn-Yih Lee, Tzonelih Hwang · 2001
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.
