Uniform Distribution Routing Algorithm Based On Tor Network

With the development and application of Internet, we are paying more and more attention to network security and personal privacy. However, the existing network security technologies are only concerned about the security of information and data, and ignoring the identity information of both sides of communications. Attackers can obtain this information using easy technologies, such as traffic analysis or eavesdropping, it is a great threat to user personal privacy. Based on such demand, anonymous communication system was come into being, and hiding the identity of communications is it's the most important purpose. It is widely used in anonymous voting, e-commerce, e-government, and military aspects.This paper begins by describing the concepts of anonymous communication systems. Choosing the most widely used Tor anonymous communication system as the main object of the study, this paper analyzes the communications link established principles and mechanisms, the node route selection algorithm and security risks in Tor. We propose a random uniform distribution routing algorithm, increasing the cost of the attacker to steal information, improve the safety of the Tor anonymity network performance. Finally, through small-scale simulation experiments, we verify the theoretical analysis, and confirm the improvement of the new algorithm.
