摘      要：Cloud manufacturing is one of the three key technologies that enable intelligent *** paper presents a novel attribute-based encryption(ABE)approach for computer-aided design(CAD)assembly models to effectively support hierarchical access control,integrity verification,and deformation protection for co-design scenarios in cloud *** assembly hierarchy access tree(AHAT)is designed as the hierarchical access ***-related ciphertext elements,which are contained in an assembly ciphertext(ACT)file,are adapted for content keys decryption instead of CAD component *** modify the original Merkle tree(MT)and reconstruct an assembly *** proposed ABE framework has the ability to combine the deformation protection method with a content privacy of CAD *** proposed encryption scheme is demonstrated to be secure under the standard *** simulation on typical CAD assembly models demonstrates that the proposed approach is feasible in applications.
