Abstract
A verifiable secret sharing allows the dealer to share a share with some participants and can be verified the correctness. Stadler extended the idea and presented a notion of Public Verifiable Secret Scheme (PVSS), which has the property that any one can verify the validity of the share from the sender, but neglects the deceit of receiver. In this paper, we first give a formal definition of strong PVSS (SPVSS) based on PVSS and propose a specific SPVSS scheme. The scheme solves the cheating problems on both sides, which has strong verification requirements. Finally, we show our scheme satisfies the definition of strong PVSS.
