Abstract: A dynamic secret sharing scheme based on discrete logarithms is proposed which can detect cheaters. The shadow of every participant can be used by many times without restriction, so that the system secrets can be renewed without renewing the shadows of the participants. The system can also accept a new participant or fire a participant freely. Due to its properties of security and efficiency, the scheme will find wide applications in distributed key escrow and electronic commerce.
Key words: secret sharing, discrete logarithms, dynamic secret sharing, cheating
