Verifiable hierarchical threshold multi-secret sharing scheme
可验证的多等级门限多秘密共享方案

In the current multi-level secret sharing scheme, the presence of higher-level participants could be replaced by several lower-level participants. As to the multi-secret sharing scheme, secrets could only be shared under the same level. To eliminate the two limitations, based on Birkhoff Interpolation and the intractability of discrete logarithm, a new verifiable hierarchical threshold multi-secret sharing scheme was proposed. This scheme simultaneously maintained multiple levels and multiple secrets for every threshold level. Every participant kept one sub-secret only, which was convenient to manage and use.
