Yolan is an applied cryptographer delving into (and mostly dwelling on) cryptography, secure coding, and other fun things. He has previously spoken at Black Hat USA, BSidesLV, Cryptovillage, NorthSec, GopherConEU and DEF CON on topics including automation in cryptography, public keys vulnerabilities, elliptic curves, post-quantum cryptography, functional encryption, open source security, and more! He notably introduced the first practical fault attack against the EdDSA signature scheme, and orchestrated the full-disclosure with code of the CurveBall vulnerability.
