Abstract:

A practical member enrollment protocol for threshold schemes is presented. The protocol can generate a new share for a new member when this member joins a threshold system. At the same time, the old members do not need to change their old shares. Different with previous protocols, the new protocol is very simple and efficient. Also, it is proved that the new protocol is correct and secure.

Key words: verifiable secret sharing, secret redistribution, threshold scheme
