Secret Service's Distributed Computing Project Aimed at Decoding Encrypted Evidence
|
News Item | 2005-03-29 00:01:27 | For law enforcement officials charged with busting sophisticated financial crime and hacker rings, making arrests and seizing computers used in the criminal activity is often the easy part. More difficult can be making the case in court, where getting a conviction often hinges on whether investigators can glean evidence off of the seized computer equipment and connect that information to specific crimes. |

Security Analysis of a Cryptographically-Enabled
|
News Item | 2005-01-30 21:48:48 | Steve Bono,Matthew Green,Adam Stubblefield,Ari Juels,Avi Rubin,Michael Szydlo describe their success in defeating the security of an RFID device known as a Digital Signature Transponder (DST). Manufactured by Texas Instruments, DST (and variant) devices help secure millions of SpeedPassTM payment transponders and automobile ignition keys. Here is their story. |

What's the difference between a cipher and a code? Encryption schemes explained.
|
News Item | 2004-11-16 00:57:08 | Data encryption has become a sad necessity for responsible data managers. However cryptography is jargon-heavy even by the discouraging standards of the IT world – symmetric and asymmetric cryptosystems, public versus private keys, digital signatures, hash algorithms, RSA, DES, Rijndael, PGP, MD5, SHA-1, https, secure sockets, Camellia, IDEA; what does it all mean? What are the differences? Relative advantages and disadvantages? Hopefully this article will clear some of the fog. |

Fingerprinting Your Files
|
News Item | 2005-02-05 20:55:56 | Three cryptographers at Stanford University recently came up with a clever solution to the persistent problem of identity theft on the Internet. Wily hackers in Russia, China, and other countries send out piles of e-mail messages looking like they came from some financial institution such as Citibank or Paypal. Millions of consumers get these messages, which have embedded HTML links in them that take the unsuspecting recipient to look-alike websites run in faraway places. You're prompted to enter a username and password and then—wham—the hacker has the keys to your bank account. |

First quantum cryptographic data network
|
News Item | 2006-08-31 16:02:22 | A joint collaboration between Northwestern University and BBN Technologies of Cambridge, Mass., has led to the first demonstration of a truly quantum cryptographic data network. By integrating quantum noise protected data encryption (quantum data encryption or QDE for short) with Quantum Key Distribution (QKD), the researchers have developed a complete data communication system with extraordinary resilience to eavesdropping. |

super-secure computer network

News Item | 2004-09-16 00:12:37 | A quantum leap: Researchers create super-secure computer network By Theo Emery / Associated Press Wednesday, September 15, 2004 CAMBRIDGE -- It's a hacker's nightmare but a dream for bankers and spies: A computer network so secure that even the simplest attempts to eavesdrop will interrupt the flow of data and alert administrators to the snooping. |

Quantum decoys foil code-breaking attempts
|
News Item | 2005-07-23 09:30:29 | Computer code-makers may soon get the upper hand on code-breakers thanks to a new quantum cryptography method designed at the University of Toronto. Quantum cryptography uses particles of light to share secret encryption keys relayed through fibre-optic communications. |

Quantum cryptography has marched from theory to laboratory to real products
|
News Item | 2005-01-20 23:13:29 | At the IBM Thomas J. Watson Research Laboratory, Charles Bennett is known as a brilliant theoretician--one of the fathers of the emerging field of quantum computing. Like many theorists, he has not logged much experience in the laboratory. His absentmindedness in relation to the physical world once transformed the color of a teapot from green to red when he left it on a double boiler too long. But in 1989 Bennett and colleagues John A. Smolin and Gilles Brassard cast caution aside and undertook a groundbreaking experiment that would demonstrate a new cryptography based on the principles of quantum mechanics. |
