An Identity (ID)-Based and Self-Certified Secret Sharing Scheme
Pei Qing · Chinese Journal of Computers · 2010
In order to resolve the secure distribution problem in the existing secret sharing schemes,based on Girault's key exchange protocol,a new secret sharing scheme is proposed,which adopts the ID-based public key cryptography technology.And then,security and performance analysis is made on this scheme.Each participant's private key is used as his secret shadow,which are not selected and redistributed by the secret dealer any longer.The private key of each participant is chosen by the participant himself,and even the trusted third party cannot gain his private key.At the same time,anyone can verify every participant's public key,and judge whether it is valid in the form of off-line.Analysis shows that the proposed ID-based secret sharing scheme is more secure and effective than others,and it can be more applicable.
