Secure Multi-layered Threshold Secret Sharing Scheme
Wei Wang · Journal of Guangzhou City Polytechnic · 2011
A multi-layered threshold secret sharing scheme is proposed considering the fact that Secret Sharing among multi-layered organizational structure.The security of the scheme is based on the RSA cryptosystem and Shamir threshold secret sharing scheme and hash function.In the scheme,each participant′s secret shadow is selected and saved by himself and even the secret dealer know nothing about it.Each participant can share many secrets with other participants by holding only one secret shadow.The scheme do not require a secure channel between each participant and the dealer,also algorithm can guarantee secure delivery and verify authenticity of information.
