Scalable threshold scheme without a trusted third party
Biao Li, Shensheng Zhang, Kefei Chen · 2002
The change on membership of participants and its impact on the application of threshold cryptography are seldom considered in literature. However, it is a very important problem in secure dynamic cooperation in modern business environment. In this paper, a scalable threshold scheme is proposed as preliminary study on this field. Our proposal is to put together multiple simple Shamir's threshold schemes to realize a scalable one, without requiring any cryptographic assumption and a trusted third party.
