David McGrew is a Fellow at Cisco Systems, where he leads research and development to detect threats, vulnerabilities, and attacks using network data, and to protect data through applied cryptography. He pioneered the commercial use of encrypted traffic analysis to defend networked information systems, designed authenticated encryption and secure voice and video standards that are in widespread use, most notably GCM and Secure RTP. David has created and contributed to open source projects, published research results, championed open, patent/royalty-free cryptography, and co-founded the IRTF Crypto Forum Research Group. Prior to joining Cisco, he was a cryptographic scientist at Trusted Information Systems. He holds a PhD in Physics from Michigan State University and lives in Maryland, the capitol of cybersecurity.
