%X A new multi-secret sharing scheme was proposed based on elliptic curve cryptography and PANG-WNAG's(t,n) multi-secret sharing scheme.The scheme has properties as follows:(1) participants can choose sub-secrets by themselves;(2) shadows of every participant can be renewed periodically.Compared with PANG-WANG's scheme,this scheme compensates for the disadvantages of the original scheme such as sub-secrets must be chosen by dealer and shadows cannot be renewed,so this scheme has better flexibility and higher security.
