Anonymization of Network Traffic

Abstract—The security challenge coming with the popularity of web-based applications is a serious matter. The privacy of the data sent back and for has become a crucial issue. As a matter of
fact, in one of their most recent publications, Chen et al analyzed this problem and showed that, although the existence of powerful communication security systems such as HTTPS, WPA/WPA2 Wi-Fi encryption, several high-scaled Webapps are exposed to side-channel attacks using timing and a subset of the applications’ internal information flows. In response to it, Liu et al developed a privacy model, introduced by Chen et al , to prevent this threat. The approach aims to protect the size of the packets exchanged during the
communication between the client and the server and makes use of the privacy-preserving traffic padding (PPTP). Our paper proposes a novel economical mechanism to achieve this PPTP on
the basis of the well-known privacy preserving method called ldiversity.
