Design and analysis of firewall-penetrated scheme based on trusted host

On the basis of various firewall-penetrated technologies, a novel firewall-penetrated technology based on trusted host, which can realize the communication between penetrating host and protected host, is proposed in this paper. Meanwhile, the firewall-penetrated evaluating model and its formalized statement is also proposed by quantizing penetrated level, penetrated quality, and penetrated hiding. Finally, the firewall-penetrated technology based on trusted host is analyzed under the firewall-penetrated evaluating model, and the experimental results show that this technology has obvious penetrating effect and high penetrating quality.
