Zou Hui, Jiandong Wang, Fengjia Lu · 2009
In multi-secret sharing schemes, the secrets can only be shared in the same threshold. A multi-level threshold multi-secret sharing scheme with periodic renewing based on the intractability of the discrete logarithm is proposed. The scheme has the following characteristics: The secrets can be shared in the multiple level threshold .The multiple secrets can be shared in the same level threshold. The master shadow of every participant can be renewed periodically.
