Integrated the idea of secret sharing scheme and digital signature technology, a threshold signature scheme with multi-organizes is proposed. This scheme uses the method of multiple secret split, it's security is based on the large number resolution and discrete logarithm, and the analytical results show that the scheme is effective security and simple in entirety. Since 1979 Shamir proposed the first (t, n) threshold secret sharing scheme, peoples have researched in secret sharing scheme incessantly. Now it is one important field in cryptology. The secret sharing scheme and digital signature technology were combined to form the threshold signature which extended the field of application.
