A Simulation Design of Cascade Generation Method for Anonymous Network

In this paper, we propose HAMA design, a flexible, secure and better performance cascade generation scheme for anonymous network application based on Mixnets. Different from the existing source routing methods that randomly select Mix nodes to generate cascade link, we firstly propose a hierarchical adversary model from the perspective of application users to meet the different anonymity requirements of various application clients. And then, the multi-attribute constraints of cascade link are further analyzed, such as node bandwidth, nation, provider, location and link length, etc. Furthermore, corresponding cascade generation algorithms are designed according to the hierarchical adversary model. The final analysis and evaluation prove that HAMA design is superior to the existing method of randomly selecting nodes to generate cascade link in terms of anonymity and performance. Moreover, HAMA design can not only provide flexible anonymity choices for application designers, but also promote the development of anonymous network in simulation range.
