In order to prevent sub-secret transmitting in public channel,this paper proposes a secret sharing scheme based on intractability of discrete logarithm and commutativity of modular exponentiation.Results prove that participants choose their own private keys by themselves,they avoid cheating of dealer,decrease the computational cost of dealer and ensure the reusability of this scheme,moreover trusted participant may join or leave the group to ensure the dynamic of this scheme.
