One-Shot Signatures and Applications to Hybrid Quantum-Classical Authentication

Explore the concept of one-shot signatures and their applications in hybrid quantum/classical authentication in this 22-minute conference talk. Delve into signature delegation, one-shot chameleon hashing, and blockchain-less cryptocurrency with classical communication. Learn about budget signatures, non-interactive proofs of quantumness, ordered signatures, and single signer signatures. Discover how to build a chameleon hash relative to an oracle, gaining insights into cutting-edge developments in quantum cryptography and authentication systems.
