Quantum Cryptography: As Awesome As It Is Pointless

2008-10-16 04:00:00 by Bruce Schneier in Wired Security
 
...cryptography is back in the news, and the basic idea is still unbelievably cool, in theory, and nearly useless in real life The idea behind quantum crypto is that two people communicating using a quantum channel can be absolutely sure no one is eavesdropping. Heisenberg's uncertainty principle requires anyone measuring a quantum system to...

Beating the codebreakers with quantum cryptography

2008-04-29 12:30:35 by Editor in Digg / Security
 
Cryptography is an arms race, but the finish line may be fast approaching. Up to now, each time the codemakers made a better mousetrap, codebreakers breed a better mouse. But quantum cryptography theoretically could outpace the codebreakers and win the race. Forever

Keyczar: Safe and Simple Cryptography

2008-08-11 11:06:00 by Panayiotis Mavrommatis in Google Online Security Blog
...Cryptography is notoriously hard to get right and if improperly used, can create serious security holes. Common mistakes include using the wrong cipher modes or obsolete algorithms, composing primitives in an unsafe manner, hard-coding keys in source code, or failing to anticipate the need for future key rotation. With these risks in mind,...

Camera phone Biometrics An Alternative to Cryptography?

1970-10-28 13:11:46 by Editor in IT Security - The IT Security Industry's Web Resource
 
...cryptography: each measurement, even when taken by the same device, of the same feature on the same person will differ slightly. This noise in the data makes it difficult to extract a cryptographic key in the traditional sense. Other recent work has shown that its possible to use just the noise in a biometric measurement to generate a...

Martin Hellman on the Invention of Public-Key Cryptography

2008-03-25 13:21:04 by schneier in Schneier on Security
 
At the DISI conference last December, Martin Hellman gave a lecure on the invention of public-key cryptography. A video is online (it's hard to find, search for his name), along with PowerPoint slides Unfortunately, the video isn't set up for streaming; in order to view the it, you'll have to download the ten files, then use a fairly recent...

What do you want to know about Cryptography in the Enterprise ?

2008-01-04 02:06:57 by Erik T. Heidt in Art of Information Security
 
I am working on a presentation entitled Lessons Learned Deploying and Managing Enterprise Cryptosystems . I will be presenting this at Information Security World 2008 . In the 45 minutes I have for the presentation, it is my goal to touch on several key lessons learned in my work with cryptographic controls over the past several years....

Errors in Quantum Cryptography?

2008-04-21 13:02:00 by Manu Namboodiri in Data Protection, Management and Leakage
 
...cryptography, the holy grail of 100%, bullet-proof encryption The researcher quotes - "We didn't expect to find a flaw". Makes one wonder if there is any technology that can claim it I think there are no foolproof solutions, only fools (maybe too strong a word, but the rhyming was too good to pass up!) who believe so
