中文摘要：
提出了基于多路径网络编码的信息分割传输策略ITNC（information slicing and transmitting with multi-path network coding）,并基于ITNC提出了一种无需密钥基础设施的匿名通信机制AC-ITNC（anonymous communication mechanism based on ITNC）.该机制将建路信息分割后编码传送,每个编码节点都对转发信息进行再次随机编码,编码系数与编码信息沿不同编码路径分离传输,从而可以在不需要密钥机制的情况下进行匿名建路.理论分析与仿真结果表明,AC-ITNC与单纯依靠源节点信息分割而中间节点不编码的匿名建路机制相比,显著提高了匿名系统的抗合谋攻击能力.
英文摘要：
This paper first proposes a new information slicing and transmitting method ITNC （information slicing and transmitting with multi-path network coding） with multi-paths network coding. Next, a novel anonymous communication mechanism AC-ITNC （anonymous communication mechanism based on ITNC） without key infrastructure, which is based on ITNC, is presented. In the new mechanism, the anonymous path setup information is sliced into pieces, and every piece is coded by the random coding coefficient. The coding coefficient and coded information pieces are delivered along different paths, which make the anonymous paths be set up in the case of non-cryptographic scheme. Theoretical analysis and simulation results show that AC-ITNC can significantly improve resistance against conspiracy attacks in an anonymous communication system within complete distributed environment without key infrastructure.
