A verifiable multi-organization multi-secret sharing scheme is proposed,which is based on the idea of Shamir threshold system.It is extension of Shamir threshold scheme.The scheme can ensure the secure storage of important information and secret data,transmission and the legal utilization.In this scheme,the main construction method used in the Lagrange interpolation polynomial and number theory of knowledge,validation phase uses some knowledge of discrete logarithm,which is more complicated in the calculation.Through the use of these mathematical knowledges,each participant in the secret recovery phase can verify the validity of the secret share of the other participants provided for preventing the other participants from cheating,The program's security is based on the intractability of discrete logarithm.After the final analysis,the program is proved to be feasible and safe.
