Keeping Secrets: Cryptography In A Connected World
Δημοσιεύτηκε στις 14 Αυγ 2014
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.
PARTICIPANTS: Brian Snow, Simon Singh, Orr Dunkelman, Tal Rabin
