Alfred Menezes is a Professor at the University of Waterloo in Ontario.  In 2001, he won the Hall Medal from the Institute of Combinatorics and its Applications.  Alfred is the lead author of the Handbook of Applied Cryptography, and  which has been cited over 25,000 times. He has published many high impact papers, especially in areas of public key encryption and elliptic curve cryptography, and was the co-inventor of the ECDSA signature method. His website for online courses is https://cryptography101.ca. The "Cryptography101: Building Blocks" and "Cryptography 101: Deployments" courses are lectures from the undergraduate "Applied Cryptography" that he has taught at Waterloo since 2000. The former includes a five-lecture introduction to elliptic curve cryptography. He also has a course on "Kyber and Dilithium", and soon an intro to "Lattice-based cryptography".   Video recording: https://www.youtube.com/watch?v=l5GWFAewQ80
