Teaching
Reading Group

We conduct reading groups on exciting, trendy and classic topics in cryptography where all the lab members get together and hold interactive presentations and discussions to build deep understanding of the particular area and to initiate research.

Oblivious Transfer

The reading group on Oblivious Transfer was conducted in the summer of 2015. The logistics and useful links can be found here.

Circuit Garbling

The reading group on Circuit Garbling was conducted from March-May 2017. The logistics and useful links can be found here.

Broadcast and Byzantine Agreement

The reading group on Broadcast and Byzantine Agreement was conducted in the summer of 2017. The logistics and useful links can be found here.

Pets (Privacy Enhanced Technologies)

The reading group on Applied MPC (with focus on privacy-preserving ML) started from January 2018. The logistics and useful links can be found here.
