A novel inter-enterprises authentication scheme for virtual enterprises based on variable privilege sets

In order to meet special requirements of VE's inter-enterprises authentication under different organization structures, a generalized VCA scheme based on variable privilege sets was proposed, in which the paritcipants' privilege sets were allocated flexibly according to VE's different organization structures, and by constructing corresponding variable multi-parties protocols for VCA's creation and running, VE's participants can authenticate each other effectively. Security Analysis shows that, this generalized VCA scheme is more suitable for the complicated and dynamic environment of VE than the previously published VCA schemes.
