Jason Donenfeld is an independent security researcher and software developer, with a broad background of experience, well-known in both the security community and the open source world, and has pioneered several exploitation techniques. He has worked with many severe vulnerabilities in widespread software projects, including working on 0-day vulnerabilities in the Linux kernel, as well as extensive hardware reverse engineering. When he's not putting microchips under the scope, Jason can be found making and breaking cryptography, usually in ways that combine his low-level systems knowledge with cryptographic concerns. His security work spans advanced mathematical and geometric algorithms, cryptography, and remote exploitation. Jason founded Edge Security (www.edgesecurity.com), a highly capable security consulting firm, with expertise in vulnerability discovery, security assessments, cryptography, reverse engineering, hardened development, and physical security.
