If a quantum computer can be built, it would threaten most public-key cryptography deployed today. My workshop would minimally cover quantum computing, and then go on to quantum-resistant (AKA) post-quantum algorithms, their performance and security characteristics, and threats to deployment.
Michael Hamburg is a cryptographer working at Rambus. He specializes in elliptic curves and lattice key exchange, as well as efficient hardware and software implementations. He (co)designed the Goldilocks elliptic curve, the Ristretto point encoding, the Elligator2 hash-to-point primitive, and the ThreeBears post quantum encryption algorithm.
