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 uses verifiable secret sharing technique to against cheating by dealer and cheating by participants. Our scheme is proactive secure, participants will update the sub-secret periodically without dealer?s 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 correct, secure and efficient.
