Abstract

The invention discloses a creditworthiness control method and a creditworthiness control system for an anonymous communication system, and relates to the technical fields of information security and anonymous communication. A credit mechanism is introduced into the conventional anonymous communication system to calculate creditworthiness values of each node and perform routing according to the creditworthiness values, so a routing algorithm and a rerouting mechanism of the conventional anonymous communication system are improved, types of attacks and maladaptive behaviors such as malicious node attacks, selfish behaviors, Free-rider behaviors and the like of users can be prevented, and the security of the system is improved under the condition of substantially not reducing the efficiency of the system.

Description

technical field [0001] The invention relates to the technical field of information security and anonymous communication, in particular to a reputation control method and system of an anonymous communication system. Background technique [0002] Chaum first proposed the concept of anonymous communication in 1981. At present, it is necessary to study the application of anonymous communication technology in a large-scale network environment and the anonymous communication system that can be deployed on an open network. The important purpose of anonymous communication is to hide the identity of the communication participants (namely, the initiator / receiver or their communication relationship), prevent it from being discovered by its partners and other third parties, and make the user's personal privacy and communication content more secure. good protection. [0003] Modern anonymous communication technology has attracted widespread attention because of its wide range of applica...
