In our previous session we looked into Mixnets, more specifically Loopix. With this session we stayed in the space, talking about a network adopting many concepts from Loopix, namely Nym. As a preparation, we read section 1 through 4 of the Nym whitepaper. Introduction Network-level surveillance The Nym Network Design Mixnet for Network-Level Privacy Diaz, Claudia, Harry Halpin, and Aggelos Kiayias. “The Nym Network.” (2021). https://nymtech.net/nym-whitepaper.pdf

34th session was on Mixnets as lots of people suggested in the past. As a preparation we read the Loopix paper. Piotrowska, Ania M., et al. “The loopix anonymity system.” 26th {USENIX} Security Symposium ({USENIX} Security 17). 2017. https://www.usenix.org/system/files/conference/usenixsecurity17/sec17-piotrowska.pdf The corresponding talk by Ania Piotrowska is very much worth watching as an additional resource. https://www.youtube.com/watch?v=R-yEqLX_UvI

In our third BGP session we focused on BGP security, more specifically we discussed how to perform hijack and interception attacks using BGP. The primary paper of the session was: Birge-Lee, Henry, et al. “Sico: Surgical interception attacks by manipulating bgp communities.” Proceedings of the 2019 ACM SIGSAC Conference on Computer and Communications Security. 2019. A good introduction to RPKI can be found here.

After our first BGP session, introducing the protocol based on the convergence problem of BGP, our second session on BGP covered route propagation and tuning. The primary paper was: Gray, Caitlin, et al. “BGP Beacons, Network Tomography, and Bayesian Computation to Locate Route Flap Damping.” Proceedings of the ACM Internet Measurement Conference. 2020.

We decided to turn our interest to BGP which we will devote 3 sessions to. In today’s session - the first one - we introduced BGP, looked at the convergence problem, as well as the solution suggested in the paper below. Gao, Lixin, and Jennifer Rexford. “Stable Internet routing without global coordination.” IEEE/ACM Transactions on networking 9.6 (2001): 681-692. To play around with BGP as well as general Internet routing: ...
