The Short Share Secret Sharing Agreement with Matrix Factorization

,( n r threshold secret sharing with short share and high efficiency. The length of secret share that each participator needs to conserve has no relation with the length of the secret. So our scheme has a very high space, computation and communication efficiency. It has a very important application when the secret is a big privacy file, a big message transmitting in an insecurity channel, a secret data base shared by several participant or magnanimity data in distributed storage.
