Title: Advances in Non-Malleable Cryptography
A central challenge in the design of secure systems is to defend against man-in-the-middle attacks, where an adversary can arbitrarily tamper with the messages exchanged by two parties over a communication channel. Starting with the early nineties, an important research goal in cryptography has been to build ``non-malleable'' cryptographic protocols that are resilient to such attacks.
In this talk, I will describe my work that culminates this two-decade long research quest by constructing round-optimal non-malleable protocols based on almost minimal cryptographic assumptions. I will also discuss how the techniques developed in these works have transcended cryptography and found applications in randomness extraction, coding theory, and, complexity theory. I will also briefly talk about my work on applied cryptography and its impact.
