A New Dynamic Threshold Secret Sharing Scheme to Identify Cheaters
Wang Qing-ju · Journal of East China Jiaotong University · 2005
A threshold sheme is a method whereby pieces of the secret , called shares are distributed to participants so that : the secret can be reconstructed from the knowledge of any or more shares, and the secret cannot be reconstructed from the knowledge of any or less shares. A dynamic secret sharing sheme is an especial threshold sheme.Its character is that the secret can be renewed without modifying and rebaking any share. This paper proposes a new dynamic threshold secrete sharing sheme to identify cheaters by integrating the discrete logarithm problem and the integer factorization problem with higher roots problem.This paper also discusses the security of the sheme.
