Philippe Lamontagne Research Officer, NRC
Philippe Lamontagne completed his Ph. D. in quantum cryptography from the Universté de Montréal in 2018. Since his graduation, he has been working as a machine learning analyst at Irosoft, a Montreal based company specializing in NLP. In April 2019, he will take on the role of research officer that Canada's National Research Council.
Talk: Post-Quantum Manifesto
Significant advances in quantum computing capabilities would spell the end of the public key infrastructure as we know it. Shor's algorithm, a quantum algorithm for efficiently solving the discrete logarithm problem, means that computational problems whose hardness is the foundation of public key crypto are easy to compute on a quantum computer.
All is not lost for asymmetric cryptography. Quantum key distribution (QKD) allow the establishment of a shared secret key under the sole assumption of an authenticated channel. Post-quantum cryptography looks instead to replace the hardness assumptions on which public-key cryptosystems are built.
This talk will review computational assumptions relied upon by traditional cryptography and why they fail the coming of the quantum computer. We will review proposed alternatives that are part of NIST's post-quantum cryptography standardization's efforts.
