%X Cryptanalysis of the improved efficient ID-based signcryption scheme which was proposed by Xiao, et al. shows that the scheme can't resist indistinguishability under chosen ciphertext attack and dishonest recipient's general forgery attack. This paper proposed an improved signcryption scheme to overcome these security problems. The new scheme had the indistinguishability against adaptive chosen ciphertext attacks property and was secure against an existential forgery for adaptive chosen messages and identity attacks in random oracle model, and the security was reduced to decisional bilinear Diffie-Hellman problem and computational Diffie-Hellman problem.
