RBP: a website fingerprinting obfuscation method against intelligent fingerprintingattacks

Abstract

A significant danger to website privacy and web security is posed by website fingerprinting (WF), a passive traffic analysis attack. It gathers the network packets created when a user accesses a website and then employs a number of approaches to identify patterns in the network packets that can be used to determine the kind of website the user is accessing. Numerous anonymous networks, like Tor, can satisfy the need to conceal identify from users while participating in network activities, but they are also vulnerable to WF assaults. In this research, we present Random Bidirectional Padding, a website fingerprinting obfuscation technique against sophisticated fingerprinting techniques (RBP). It is a cutting-edge website fingerprinting defence technology built on time sampling and random bidirectional packet padding that can change real packet distribution to destroy Inter-Arrival Time (IAT) features in the traffic sequence and increase the difference between datasets with random bidirectional virtual packet padding. We test the efficiency of thedefence against cutting-edge website fingerprinting attacks in actual circumstances.
