Self-certified threshold multi-secret sharing scheme under different access right
Jiandong Wang · Computer Engineering and Applications Journal · 2011
In order to solve the secure distribution problems in the existing secret sharing scheme under different access right,based on the ID-based public key cryptography technology,a new secret sharing scheme under different access right is proposed,which adopts two polynomials,and then a generalized scheme is given.In the scheme,each participant's share is selected by the participant himself and secret dealer separately;the shares can be repeatedly used for the reconstruction of multiple secrets.The cheating between participants can be detected by verifying every participant's identity and share.Analysis shows the proposed scheme is secure.Furthermore,its efficiency is also better than others.
