  • Spotlight: Life without Cryptography

    Strip away the trimmings of a traditional science presentation, add cocktails, and you have WSF Spotlight. How much of your information would you rather stay hidden from public...

  • What Is the Future of Cryptography?

    Historically, as advances were made in the fields of engineering, mathematics, and physics, so the field of cryptography has advanced with them—usually by leaps and bounds....

  • What Is Public Key Encryption?

    A 1976, two Stanford researchers devised an encryption method that revolutionized cryptography by making it easier to send encrypted information without having to agree on a key...

  • Human Trust vs. Cyber Trust

    Between two humans, trust is based on personal interactions, with the ability to revoke said trust, and not necessarily with the subsumed trust of third parties. But in exchange...

  • Cyber-Terrorism: A Question of Intent

    Security expert Brian Snow lays down the uncomfortable truth: The technology exists today for a malicious group to cripple our nation’s infrastructure; all they need is the...

  • Cryptography’s Human Problem

    How safe is your data? Your money? Your identity? No matter how sophisticated and complex a security encryption system, all of it can be foiled by the simplest of human errors....

  • The Importance of Implementation

    Just as human error can foil a good encryption, so can sloppy implementation. Brian Snow, a former NSA security expert, describes in simplified examples how a badly built...

  • The Enigma Machine Explained

    As technology increases, so do the methods of encryption and decryption we have at our disposal. World War II saw wide use of various codes from substitution ciphers to employing...

  • Cryptography: Codes, Ciphers, and Connections

    The encryption of information is as old as information itself. Ever since two people wanted to pass something along, so has there been a third party who wanted to be privy to it....

  • Public Perceptions of Privacy

    Would you give somebody your bank PIN for a candy bar? Cryptanalyst Orr Dunkelman tells the cryptography panel about a surprising study that found that most people would. Why is...

  • The Science and Business of Keeping Secrets

    Cryptography is a unique field in both it's age and the way it spans many different fields. Psychology, engineering, mathematics, physics, and sociology all get wound up together into one goal.

  • Machine Encryption

    As technology increases, so do the methods of encryption and decryption we have at our disposal.

  • Instant Reaction: Cryptography in a Connected World

    Cryptography—the art and science of hiding information—was once the work of scholars with a bit too much time on their hands but is now inescapable in our digital world. The truly brilliant panelists explained not only how encryption works on the web (Think: really hard...

  • Information Is Everywhere, How Can Science Protect It?

    Underscoring the importance of encryption in our increasingly data-driven digital lives, this year's World Science Festival features its first-ever session on cryptography, entitled "Keeping Secrets: Cryptography in a Connected World." During this discussion expect a...

  • All the World’s Secret Numbers

    Humans invented cryptography before they invented the alphabet. Over 4,000 years hieroglyphics turned to letters and letters to numbers. Early encryption algorithms based on simple permutations of the alphabet were replaced by locally varying (letter by letter) substitution...
