AS57821 up and running

Just yesterday AS57821 announced its first prefixes and today RIPE Stats says the prefixes are visible to almost the entire Internet. Hooray! Today, in the evening, I will fly to Frankfurt setting up a wire to the nearest IX and start peering.

SSL/TLS and the BEAST attack

This talk is about the history, the design goals, and the protocol stack of SSL/TLS. It also covers the BEAST attack on cipher block chaining and how the attack is prevented in later versions of TLS. I gave the talk during a cryptology lecture. You can grab the slides here.
