New On-Line Secret Sharing Scheme Using Hash Function
Wen Feng Ji, Soohyun Oh, Seungjoo Kim, Dongho Won · 2003
In this paper,we propose an efficient on-line secret sharing scheme using one-way hash function.The proposed scheme provides the property to share multiple secrets and allows participants to be added/deleted dynamically,without having to redistribute new shares.It is able to detect and identify cheaters even if majority of the participants are dishonest,and is more computationally efficient than previous schemes.Therefore,it can be applied to multi-party protocols,group-oriented cryptosystems and etc.
