My [report](report.pdf) is available (the [design +archive](archive.tar.gz) is also). + +# Abstract + +Tor is an low latency, onion routing system that anonymizes TCP streams. One +particular Tor feature is hidden services, these provide responder anonymity, +this means the identity of the server providing the service, is hidden from the +requester (user) of the service. + +While modern web services, which can use techniques like anycast and DNS +(domain name system) round robin to distribute clients across many servers, the +main load for a Tor hidden service, will always go through a single node in the +Tor network. This has implications for the availability and scalability of Tor +Hidden Services, which has knock on implications anonymity of the hidden +service, as downtime can possibly reveal information about its real world +location. I aim to modify Tor to allow for distributed hidden services. + +This was achieved, however a deterministic property was added to the +introduction points, which can be used to attack the service. A approach to +solve this is discussed. diff --git a/projects/tor/disths/archive.tar.gz b/projects/tor/disths/archive.tar.gz new file mode 120000 index 0000000..9cced26 --- /dev/null +++ b/projects/tor/disths/archive.tar.gz @@ -0,0 +1 @@ +../../../.git/annex/objects/Kq/VW/SHA256E-s28485355--871d384d9598405e16659009749eb0b6fccb426fa7e2329cbcbbbb43fe4cfe7a.tar.gz/SHA256E-s28485355--871d384d9598405e16659009749eb0b6fccb426fa7e2329cbcbbbb43fe4cfe7a.tar.gz
