Embodiment Construction

[0029] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] A communication delay-oriented node selection method in anonymous communication provided by the present invention is improved on the basis of node evaluation in the I2P anonymous communication system, new evaluation factors are introduced and relevant statistical information is recorded, and a basic node selection algorithm is proposed. And on this basis, a communication delay-oriented node selection algorithm for reducing communication delay requirements is proposed. The basic idea: use node evaluation factors including bandwidth score, online duration score, connectivity and delay to evaluate each routing node, and form a connected group with all nodes that have connectivity with the node, and from the connected group Select nodes with high reliability to form a high-reliability group, and further select nodes with high performance from the hi...

Abstract

The invention discloses a communication delay-oriented node selection method in anonymous communication. A routing node is evaluated; high-performance routing nodes are screened out; the routing nodeswith relatively low delay are selected according to the delay of the routing nodes to form the communication tunnel, the capability of resisting negative malicious nodes is effectively improved, andmeanwhile, the routing nodes with relatively low delay are selected to form the tunnel, so that the effect of reducing the communication delay by reducing the delay of each hop of the tunnel is achieved, and the communication efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a communication delay-oriented node selection method in anonymous communication. Background technique [0002] Internet applications have penetrated into every aspect of people's lives, but the accompanying privacy protection issues have become increasingly apparent. As an important method to protect personal privacy information, anonymous communication technology has received more and more attention. As one of the very popular anonymous communication systems at present, I2P provides good anonymity through its complex encryption and communication process. [0003] The rerouting path of the I2P anonymous communication system is called a tunnel (Tunnel), and the tunnel node selection algorithm adopts the source routing method, that is, the communication initiator selects the tunnel node and creates the tunnel. The routing nodes in the I2P system subjectively...
