Abstract: An identity-based designated multi-receiver signcryption scheme for manufacturing grid was proposed based on the difficulty assumptions of the elliptic curve discrete logarithm problem and the Gap Diffie-Hellman problem. The proposed scheme could not only improve the efficiency by means of achieving encryption and authentication in one logical step, but also provided the approach to designate multi-receiver to de-signcrypt and verify the signcryption result by only one signcryption computation. The proposed scheme provided the interactive authentication approach for manufacturing grid nodes which were belonging to different trust domains. Finally, based on this property, an efficient authentication model was constructed for multi-domain manufacturing grid.
