基于WLAN的数据还原模型

提出了在公共无线局域网WLAN（Wireless Local Area Network）环境下一种数据还原模型．通过对无线局域网的数据采集与分析，利用会话重聚算法快速分类数据中的多个会话与连接，提出一种单一会话对应多个连接的方法，合并每个会话中的不同连接的数据信息，并采用多线程并发处理技术最终实现一种快速的信息重放与还原模型．最后通过对该模型的处理时延和执行效率的分析，表明该模型能够对无线局域网的数据尽最大可能的快速还原与重放．

WLAN-Based Data Reproduction Model

This paper presents a data reproduction model for network security in public wireless LAN （Wireless Local Area Network）. Through the collection and analysis of the WLAN data, this model classifies the multiple conversations with the conversation reunion algorithm. And, this paper proposes a mapping method between one conversation and multi-connections to merge the information from different connections of each conversation. Furthermore, the model uses the multi-threaded parallel processing technology to replay and reproduce the application layer traffic fast. Finally, through analyzing the processing delay and implementation efficiency of the model, it shows that the model can replay and reproduce the information efficiently in the wireless LAN.
