Explore a conference talk from the 2021 ITC Conference that delves into the concept of replacing probability distributions in security games using Hellinger distance. Learn about the bit security framework of Micciancio & Walter (2018), compare Max-Log and Hellinger approaches, and understand the Leftover Hash Lemma for Hellinger distance. Gain insights into statistical distance, also known as total variation distance, and its application in security games. Discover how this research, presented by Kenji Yasunaga, contributes to the field of cryptography and security. Follow the speaker's journey from introduction to conclusions, covering topics such as public-key encryption (PKE) security, proof overview, and related work in this 21-minute presentation from the Paul G. Allen School.
