Motivation and Context + + Prop 271 causes guards to be selected with probabilities different than their + weights due to the way it samples many guards and then chooses primary guards + from that sample. We are suggesting a straightforward fix to the problem, which + is, roughly speaking, to choose primary guards in the order in which they were + sampled. + + In more detail, Prop 271 chooses guards via a multi-step process: + 1. It chooses 20 distinct guards (and sometimes more) by sampling without + replacement with probability proportional to consensus weight. + 2. It produces two subsets of the sample: (1) "filtered" guards, which are + guards that satisfy various torrc constraints and path bias, and (2) + "confirmed" guards, which are guards through which a circuit has been + constructed. + 3. The "primary" guards (i.e. the actual guards used for circuits) are + chosen from the confirmed and/or filtered subsets. I'm ignoring the + additional "usable" subsets for clarity. This description is based on + Section 4.6 of the specification + (https://gitweb.torproject.org/torspec.git/tree/guard-spec.txt) + + +1.1 Picturing the problem when Tor starts the first time + + The primary guards are selected *uniformly at random* from the filtered guards + when no confirmed guards exist. No confirmed guards appear to exist until some + primary guards have been selected, and so when Tor is started the first time + the primary guards always come only from the filtered set. The uniformly-random + selection causes a bias in primary-guard selection away from consensus weights + and towards a more uniform selection of guards. As just an example of the + problem, if there were only 20 guards in the network, the sampled set would be + all guards and primary guard selection would be entirely uniformly random, + ignoring weights entirely. This bias is worse the larger the sampled set is + relative to the entire set of guards, and it has a significant effect on Tor + simulations in Shadow, which are typically on smaller networks. + +2. Solution Design + + We propose a solution that fits well within the existing guard-selection + algorithm. Our solution is to select primary guards in the order they were + sampled. This ordering should be applied after the filtering and/or confirmed + guard sets are constructed as normal. That is, primary guards should be + selected from the filtered guards (if no guards are both confirmed and + filtered) or from the set of confirmed and filtered guards (if such guards + exist) in the order they were initially sampled. This solution guarantees that + each primary guard is selected (without replacement) from all guards with a + probability that is proportional to its consensus weight. + +2.1 Performance implications + + This proposal is a straightforward fix to the unbalanced network that may arise + from the uniform selection of sampled relays. It solves the performance + correctness in Shadow for which simulations live on a small timeframe. However, + it does not solve all the load-balancing problems of Proposal 271. One other + load-balancing issue comes when we choose our guards on a date but then make + decisions about them on a different date. Building a sampled list of relays at + day 0 that we intend to use in a long time for most of them is taking the risk + to slowly make the network unbalanced. + +2.2 Security implications + + This proposal solves the following problems: Prop271 reduces Tor's security by + increasing the number of clients that an adversary running small relays can + observe. In addition, an adversary has to wait less time than it should after + it starts a malicious guard to be chosen by a client. This weakness occurs + because the malicious guard only needs to enter the sampled list to have a + chance to be chosen as primary, rather than having to wait until all + previously-sampled guards have already expired. + +2.3 Implementation notes + + The code used for ordering the confirmed list by confirmed idx should be + removed, and a sampled order should be applied throughout the various lists. + The next sampled idx should be recalculed from the state file, and the + sampled_idx values should be recalculated to be a dense array when we save the + state. + +3. Going Further -- Let's not choose our History (future work) + + A deeper refactoring of Prop 271 would try to solve the load balancing problem + of choosing guards on a date but then making decisions about them on a + different date. One suggestion is to remove the sampled list, which we can + picture as a "forward history" and to have instead a real history of previously + sampled guards. When moving to the next guard, we could consider *current* + weights and make the decision. The history should resist attacks that try to + force clients onto compromised guards, using relays that are part of the + history if they're still available (in sampled order), and by tracking its + size. This should maintain the initial goals of Prop 271.
