%X In this paper,a signature encryption scheme based on ellipse curve cryptosystem is proposed.The scheme perfectly integrates digital signature scheme with public key cryptosystem,it has authentication, secrecy,less computation cost and less communication cost.Then we use a threshold scheme to construct a (t,n) threshold signature encryption scheme based ellipse curve cryptosystem.The scheme has more secrecy of data transmission,robustness,requires less communication cost and performs efficiently etc.The security analysis of two scheme is proposed.
