This paper presents a new proactive secure multisecret sharing threshold scheme.In the scheme,participants can share multiple secrets and compute sub-secret for rebuilding efficiently and securely,and sub-secret hold by participant is verifiable.The scheme use verifiable secret sharing technique to against cheating by dealer and cheating by participants.The scheme is proactive secure,participants will update the sub-secret periodically without dealer intervention,old sub-secret will be obsolete and adversary can’t get any useful information from these.At the end,it is demonstrated that the scheme is security and efficient.
