| Abstract: | The architecture of a synchronous collaborative CAD/CAM system C-Superman is first introduced in this paper.Next,by analyzing the latent security threats and the running requirements of C-Superman,a security(mechan)ism for this kind of system is presented.Then,a four-tier security reference model for the synchronous collaborative CAD/CAM system is constructed.Moreover,according to the security process model of C-Superman,SHA-1 hash algorithm is used twice for the identity authentication,and the transport security of data is finally implemented by using a mixed encryption method of AES and RSA,giving consideration to the synchronization of the collaborative conversation. |
