Public-Key, Functional, & Witness Encryption

Explore advanced encryption concepts in this comprehensive lecture on public-key, functional, and witness encryption. Delve into attribute-weighted sums, existing solutions, and the false economy surrounding encryption methods. Learn about fully deniable encryption, verifier registration-based encryption, and identity-based encryption. Discover methods to obtain weakness in encryption systems and examine the question of how short a proof can be. Gain insights into individual verifiability and participate in a Q&A session to deepen your understanding of these complex cryptographic topics.
