Dynamic general secret sharing scheme
Jianjie Zhao · Computer Engineering and Applications Journal · 2007
A new dynamic general secret sharing scheme,based on the RSA cryptosystem and the Pinch’s scheme,is proposed in this paper.The scheme can identify the cheaters no matter she/he is the dealer or the participant;the leakage of the shadow of a participant will not affect the security of other participants’ shadows;the shadows can be reused when refreshing the secret;no security channel exists between the dealer and the participants,the property lower the costs of the system.
