Abstract: To improve the security and performance of the authentification protocol in manufacturing grid, identity-based authentification protocols without random oracles were established. The schemes aligned well with demands of manufacturing grid and could be used in both escrowed or escrowless mode and different domain mode. Through introducing pseudorandom function ensemble, the schemes achieved explicit mutual authentication in the standard model. The proposed protocols were efficient in computation complexity comparing to other solutions without random oracles and thus attractive in resources-constrained environment of manufacturing grid. The securities of the proposed schemes were proven in the standard model under intractability assumptions.
