Cache-based website fingerprinting attacks can infer which website a user visits by measuring CPU cache activities. Studies have shown that an attacker can achieve high accuracy with a low sampling rate by monitoring cache occupancy of the entire Last Level Cache. Although a defense has been proposed, it was not effective when an attacker adapts and retrains a classifier with defended data. In this paper, we propose a new defense, referred to as cache shaping, to preserve user privacy against cache-based website fingerprinting attacks. Our proposed defense produces dummy cache activities by introducing dummy I/O operations and implementing with multiple processes, which hides fingerprints when a user visits websites. Our experimental results over large-scale datasets collected from multiple web browsers and operating systems show that our defense remains effective even if an attacker retrains a classifier with defended cache traces. We demonstrate the efficacy of our defense in the closed-world setting and the open-world setting by leveraging deep neural networks as classifiers.
