35th DistSys Reading Group - Nym

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 DistSys Reading Group - Mixnets

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

33rd DistSys Reading Group - BGP 3

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.

32nd DistSys Reading Group - BGP 2

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.
