Keeping Secrets: Cryptography In A Connected World

Josh Zepps, Simon Singh, Orr Dunkelman, Tal Rabin, and Brian Snow discuss how, since the earliest days of communication, clever minds have devised methods for enciphering messages to shield them from prying eyes. Today, cryptography has moved beyond the realm of dilettantes and soldiers to become a sophisticated scientific art—combining mathematics, physics, computer science, and electrical engineering. It not only protects messages, but it also safeguards our privacy. From email to banking transactions, modern cryptography is used everywhere. But does it really protect us? What took place was a discussion of cryptography’s far-reaching influence throughout history from Julius Caesar’s reign to Julian Assange’s WikiLeaks, and the ways in which it—and our privacy—are constantly under assault today as threats lurk behind IP addresses, computational power increases, and our secrets move online.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
