By analyzing the ID-based signcryption scheme in the random oracle model,it finds that it is not satisfied with unforgeability and public verifiability.This paper proposes a proved certificateless signcryption scheme without bilinear pairing,and it avoids key-escrow in the ID-based encryption system and need not use certification.Analysis result shows that improved scheme is satisfied with unforgeability,verifiability,robustness,non-repudiation,it is adaptable to the wireless network requiring lower bandwidth.
