"Going out on a Limb: Accelerating Elliptic Curve Cryptography", Rohan McLure, BSides Canberra 2023

Cryptographic libraries such as OpenSSL and GNU Nettle form the backbone of security in the current day. Proving authenticity online, establishing secure communication channels etc all depend on complex mathematical structures, including algebraic groups on Elliptic Curves.
But what is an Elliptic Curve? This talk will discuss the underlying arithmetic used in ECC, why it might be unwise to roll your own crypto (even if you understand the maths), and how to perform both fast (and secure) finite field arithmetic.
Come along if you have an interest in the mathematics of cryptography and better understanding how it is implemented.
