A Secret Sharing Scheme Without A Dealer
Chunming Tang · Communications technology · 2008
The general secret sharing scheme always supposes a dealer for distributing keys, hence the dealer must be highly credible. However it is quite hard to find a qualified dealer. In this paper, a secret sharing scheme without a dealer is constructed, which is based on an Integer Span Program in a monotone access structure, and the experiment has proved this scheme, based on which a distributed key generator is proposed.
