Messaging and Message Franking - Eurocrypt 2023 Session

Watch a 59-minute Eurocrypt 2023 session on Messaging and Message Franking presented by TheIACR. Explore key topics including messaging with key updates, building UPIBE for bounded and unbounded depths, and the ongoing debate over encryption. Delve into the challenges of implementing backdoors, the negative impacts of weakening encryption, and moderation without end-to-end encryption. Learn about minimum requirements, design philosophy, and a compiler for pre-constrained group signatures. Gain insights into security requirements and performance considerations for messaging systems. Understand the complexities and trade-offs involved in modern secure communication technologies.
