Security Model for Analyzing Data Privacy in Multipath Transport

摘要

In order to investigate the enhancement of data privacy by distributing data packets via multiple paths,this paper formulates a security model and analyzes the privacy problem in multipath scenarios leveraging information theoretic concept.Based on proposed model,a privacy function related to the path number is discussed.We heuristically recommend the optimal path number and analyze the tradeoff among the performance,resource consumption and privacy.For reducing the information leakage,the data schedule algorithms are also proposed.The analytical model can provide guidelines for the multipath protocol design.
