Whitfield Diffie Cryptography Pioneer #shorts #Global #History #News

Global History News #shorts #Global #History #news Whitfield Diffie—born in 1944 in Washington, D.C.—changed how the world communicates securely. In the mid-1970s, he co-invented public key cryptography, a system that lets strangers exchange secret information over open networks. This breakthrough made online banking, e-commerce, and secure messaging possible. Before Diffie’s work, encryption required both parties to share a secret key in advance—a huge security risk. For his contributions, he earned the Turing Award in 2015, the highest honor in computer science. Still alive, Diffie continues to influence cybersecurity policy and research. Because of him, your passwords, payments, and private messages stay private.
