A first look at deep packet inspection employed by the Golden Shield

Working paper

We describe a series of tests on the capabilities of the Chinese Golden Shield. These tests focus on the Deep Packet Inspection capabilities of the Golden Shield, aiming to find out what is filtered and what is not. Our tests find that DPI triggering is not as easy to trigger as was expected, in contradiction of earlier research. We believe this is due to filtering optimisation of the Golden Shield in an effort to improve its efficiency given a limited technical capability. Our work joins a growing narrative that the Golden Shield is not able to fully monitor all network traffic in China, and makes sacrifices to focus primarily on key methods of information exchange, such as web traffic.
