Generic Authenticated Key Exchange in the Quantum Random Oracle Model

Generic Authenticated Key Exchange in the Quantum Random Oracle Model

Explore a conference talk from PKC 2020 examining Generic Authenticated Key Exchange in the Quantum Random Oracle Model. Delve into the limitations of previous work, the significance of decryption failures, and the transition from the Random Oracle Model to the Quantum Random Oracle Model. Understand the 'Oneway to Hiding' technique for extracting preimages, and examine common elements in Fujisaki-Okamoto proofs. Investigate the security challenges of 2-move protocols and gain insights into the proposed security model. Conclude by considering open questions in this field of cryptographic research.
