Saturday, August 9, 1997, 4:00 pm: From encryption to digital signatures to electronic commerce to secure voting - cryptography has become the enabling technology that allows us to take existing business and social constructs and move them to computer networks. But a lot of cryptography is bad, and the problem with bad cryptography is that it looks just like good cryptography; most people cannot tell the difference. Security is a chain: only as strong as the weakest link. In this talk Bruce Schneier will take a look at the future of cryptography: the needs, the threats, the limits of technology, and the promise of the future.
