Public Key Cryptography - Non-Interactive Threshold BBS+ and Updatable Public Key Encryption

Explore advanced public key cryptography research through this 41-minute conference presentation from RSA Conference featuring two cutting-edge academic papers. Learn about non-interactive threshold BBS+ signatures constructed from pseudorandom correlations, presented by Benjamin Schlosser from Technical University of Darmstadt, which addresses the challenge of creating threshold signatures without requiring interactive protocols between signers. Discover updatable public key encryption schemes with strong chosen-ciphertext attack (CCA) security through the work of Kyoichi Asano from The University of Electro-Communications, examining both security analysis methodologies and efficient generic construction techniques for cryptographic systems that can evolve their keys over time while maintaining robust security guarantees. Gain insights into the latest theoretical developments in cryptographic protocols that enhance both the efficiency and security of distributed cryptographic systems.
