Abstract: A new efficient ID-based signcryption scheme is proposed, in which some characteristics of bilinear map are used. Signcryption can sign and encrypt message at the same time, and has lower costs than that of “firstly sign and then encrypt”. The new ID-based scheme that is constructed in ellipse group is secure than the general scheme. In the new scheme the signed message can be reverted only by appointed receiver because of its orientability.
