Firstly, there are less secure and efficient threshold schemes; secondly, the research on multi-secret sharing is rather weak; thirdly, usual verifiable secret sharing don't consider the partners' anonymity, while it is just people's expectation. Last but not least, the problem of variety on shares is becoming a more obvious restrict of efficiency, especially in the facets of the lost and being districted of shares. On the application of verifiable secret sharing, there are also two inadequates : on the one hand , verifiable secret sharing has been used in much threshold cryptography but in less verifiable signatures.

An optimum multiple strain and processing test condition for producing micro-ecological, multiple enzyme feedstuff from beer grain with solid state fermentation was selected by using analytic hierarchy process. Meanwhile, data dispose and weight analyses to the relevant relations of all factores effecting the selection of the scheme were done after setting up a matrix. Multiple weight value of scheme X in target were X1=0.26, X2=0.41,X3=0.33 respectively, so that the optimizing multiple strains and relevant processing conditions of beer grains solid state fermentation were obtained.
