Abstract: The safety issue for Cloud Manufacturing (CMfg) platform is one of key technologies of the CMfg research.Based on analyzing the differences and similarities of structures and functions of CMfg platforms for two kinds of enterprises: Small-and Medium-sized enterprises (SMEs) and Group Enterprises (GEs),a new hybrid and combined hierarchical architecture of CMfg platform was established.By considering and analyzing the safety requirements of each layers of proposed CMfg platform architecture,a security requirement model for CMfg platform was created.From the views of three points: data security,access control and network transmission security,the reliabilities and applicabilities of various security technologies mainly in public cloud platform for SMEs CMfg were compared and analyzed,as well as in private cloud platform for GEs CMfg.An establishment method for security architecture of CMfg platform was submitted,and the applicability in representative CMfg platform was analyzed,which could be referred to build CMfg platform of SMEs and GEs.
