In the foreseeable future, data transmission and information exchange play important roles in intelligent transportation (ITS) systems. Heterogeneous networks (HetNets) currently emerge in order to provide large amount of data flow and customized network services. Virtualization technology is considered as one most promising approach towards HetNets implementation, aiming at managing virtualized HetNets resources in a convenient manner. In the virtualization research, the virtual resource allocation is another core technical issue. Though the issue has been well addressed in recent years, the secure virtual resource allocation has not been fully investigated yet. Hence, we research the secure virtual resource allocation for HetNets in this paper. Following the introduction of the security model for HetNets, we propose one effective heuristic strategy, incorporating the greedy and isolation methods. Experiment work is conducted so as to validate the efficiency of the heuristic strategy. Experiment results vividly reveal that our heuristic strategy, incorporating the greedy and isolation methods, performs better than the counterpart without using the isolation method, in terms of average virtual network service acceptance.
