It’s a Dhcp service which will convert the pi into a Dhcp server and will lease ip addresses and other network settings for machines that will connect to the Pi via access point.Īnd edit the file as shown in the figure below This service allows you to create virtual access point. This software will turn the wi-fi adaptor into a Access point. Hostapd is a daemon to run Access point service and authentication. This process will help the firewall to learn pattern to be more efficient in detecting possible bridges. If the connection is unsuccessful that would mean that it is genuine https traffic. Through deep packet inspection firewall can forward suspected tor bridge address to the raspberry pi proxy then pi will try to form a circuit using that bridge to the tor network if the connection is successful the firewall can block add the bridge to the deny list. Raspberry pi Tor proxy can be used in conjunction with a DPI firewall to block unknown tor bridges. Moreover, how http traffic in tor network can help identify tor users and bridges will be discussed. Comparison results will be used to understand how great china firewall is blocking private bridges. This data will be compared with normal https handshake. To form this connection an initial ssl handshake is made, using wireshark this handshake will be captured and recorded over and over again until enough handshakes analysed to generate statistical data. Any client connected to this device which also acts as wireless access point will establish connection to the tor network. Raspberry pi will be running as a Tor proxy server which will be relaying tor connection through to the tor network. How using raspberry pi as tor proxy can help block tor bridges is explained. post also discusses why tor traffic is hard to detect even for NG firewalls. Further this project will analyse the initial hello packet sent by the tor client to the tor network.

Project is based on threats being caused by low latency Tor anonymous network. Analysing Tor Traffic with raspberry pi Description
