Kaspersky Labs Trying to Crack 1024-bit RSA

2008-06-12 12:30:41 by schneier in Schneier on Security
 
...mathematical prowess than you can reasonably expect to find by asking nicely on the Internet. You've got to understand the current best mathematical and computational optimizations of the Number Field Sieve, and cleverly distribute the parts that can be distributed. You can't just post the products and hope for the best Is this just a way for...

Model Validation - Not Just for Quants

2006-12-26 05:10:00 by Jomni in Risk Management Quant
 
...mathematical exercise. However, bank losses from model risk are often caused by poor governance of the wider modeling process, or by a poor understanding of the assumptions and limitations surrounding the model results, rather than by errors in equations The growing importance of models in helping executives answer some of bankings most...

Is Risk-Based Security Really Possible?

2007-07-26 20:42:00 by Bryan in practical risk management
 
...mathematical calculations How does one calculate the likelihood of a security breach? The spectrum of threats is too broad and too unpredictable to have any hope of doing this. If you were just hacked by an outsider, or fell victim to a disgruntled employee, or made a simple mistake and exposed a bunch of sensitive information on a website,...

...mathematical function but indicate that the amount of money raised is in relation to the revenue of the company and is the exponential factor involved in finding the acquisition price. I use squared in deference and in honor of Einstein's theory, but it actually means some exponent of the R and V, not necessarily the square of them So what do...

Can a math equation solve your disaster?

2008-04-14 13:00:00 by Editor in Computerworld Security News
 
When concern about pandemics began surfacing a few years back, IBM examined the impact of an outbreak on it and its clients. It's research lead it to a mathematical algorithm that IBM believes can predict just about how any organization will be effected by and can manage the results of a disaster

Researchers tout 'functional encryption' that knows who's who

2008-04-21 00:00:00 by Ellen Messmer in Network World on Security
 
Researchers detail innovative cryptographic method they call "functional encryption" based on the concept that a complex mathematical system can produce an encrypted record that only people matching certain "attributes" will be able to decrypt

TrueCrypt's Deniable File System

2008-07-18 06:56:02 by schneier in Schneier on Security
 
...mathematical sense, we find that the environment surrounding that file system can undermine its deniability, as well as its contents. Finally, we suggest approaches for overcoming these challenges on modern operating systems like Windows. The students did most of the actual work. I helped with the basic ideas, and contributed the threat...
