Abstract: To solve the problem of complicated process in current Grid Secure Infrastructure (GSI) which led to limited scalability in gridbased manufacturing, an Identity Authentication Architecture for Grid (IAAG) was proposed. Being certificatefree, IAAG aligned well with demands of gridbased manufacturing. Moreover, identitybased cryptography, signature and authentication for gridbased manufacturing were presented. Simulation experiment indicated that the authentication protocol was more efficient and lightweight than SSL Authentication Protocol (SAP), especially more lightweight for users. This contributed to the larger gridbased manufacturing scalability.

Key words: gridbased manufacturing, identitybased cryptography, authentication
