Abstract :
A new ID-based (t,n) threshold signcryption scheme is proposed based on identity and discrete logarithm problem in finite field. By using Lagrange Interpolation Formula, the new scheme not only has the function of threshold signature, but also has the function of hiding message and designating verifier. So this scheme has authentication, secrecy, data integrity and privacy of signers, it can be used in the situation of multi-user cooperation.
