N1 - I am lucky to be surrounded by people who inspire me, believe in me, and allow me to grow. There is no better way of spending our most precious resource, time, and thus to them I am grateful. I would like to thank Renato Renner, my supervisor, who offered me an opportunity of a lifetime and opened the door to the never-ending quest of solving intriguing and challenging questions. Renato was a great inspiration; I was constantly amazed by his contributions to science and his way of thinking, as well as how determined he is to come up with a proof even when it seems impossible (these days, whenever I get stuck, I just tell myself that Renato would never give up!). Most of all, I am thankful to Renato for believing in me, moving mountains to allow me to focus on my research, and supporting me when I needed to focus on other things. I appreciate and thank the co-examiners, Andreas Winter, Nicolas Gisin, and Ran Raz, for taking the time to read my thesis, as well as Ernest Tan, Frédéric Dupuis, Jie Lin, Marco Tomamichel, and Thomas Vidick for their valuable comments on parts of the thesis. I am thankful to my collaborators. Out of them, a special thanks goes to my office mate Christopher Portmann, who was always happy to discuss the details of the details, and to Thomas Vidick for being an inspiring and motivating collaborator, an invaluable mentor, and a great friend. I was honored to be part of the QIT group at ETH, consisting of many talented people. Being part of this family allowed me to interact and learn from past and current members of the group to whom I thank. My great appreciation to Marko Gebbers for enlightening me, helping me separate the wheat from the chaff, and challenging me to become a better version of myself. I am forever grateful. Owing much more than that, I wish to thank Orna, Sheri, and Keren Arnon (mother, father, and sister, respectively), as well as my best friends, for always being there for me, even from far away, and for having an unbelievable amount of patience. I cannot thank enough my mother, Orna Arnon, and Tzvia Friedman who were always happy to fly to Zurich to help with the kids when I wanted to travel for xi a conference and my father, Sheri Arnon, who illustrated an endless number of boxes for my papers, talks, and this thesis. Finally, no words can describe my gratitude to Neer Friedman, who supported and believed in me from the first moment (pushing me into the building to meet Renato) to the last sentence of this thesis. I could have not done this without him.

N2 - Device-independent quantum cryptography is a method for exchanging secret messages over potentially insecure quantum communication channels, such as optical fibers. In contrast to conventional quantum cryptography, security is guaranteed even if the devices used by the communication partners, such as photon sources and detectors, deviate from their theoretical specifications. This is of high practical relevance, for attacks to current implementations of quantum cryptography exploit exactly such deviations. Device-independent cryptography is however technologically so demanding that it looked as if experimental realizations are out of reach.In her thesis, Rotem Arnon-Friedman presents powerful information-theoretic methods to prove the security of device-independent quantum cryptography. Based on them, she is able to establish security in a parameter regime that may be experimentally achievable in the near future. Rotem Arnon-Friedman's thesis thus provides the theoretical foundations for an experimental demonstration of device-independent quantum cryptography.
