Dynamical multi-secret sharing scheme in access structure
Rui Guo · Computer Engineering and Applications Journal · 2010
A dynamical multi-secret sharing scheme in an access structure is proposed,which is based on self-pairing on elliptic curve.A scheme on sharing points on an elliptic curve is devised.The sub-secrets of participants are chosen by themselves.The pseudo shadows are sent,so a security channel is not needed between the secret dealer and participants.The shadows do not need to be changed when the secrets are renewed,the access structure is alerted,or participants are deleted(new participant is added).The security of this scheme is examined,which is based on ECDLP problem.
