A cryptographic hash function reading guide

2007-11-23 16:01:18 by George Danezis in Light Blue Touchpaper
 
...cryptanalytic results against them (and a cute health status indicating their security Prof. Wangs attacks that forced NIST to look for better functions are a must-read, even though they get very technical very soon. A gentler introduction to these attacks is provided in Martin Schlaffers Masters thesis describing how the attacks are applied...

A New Hash Competition

2008-05-22 14:32:02 by Editor in IEEE Security and Privacy
 
...cryptanalytic results cast doubt on the current hash function standards. The relatively new NIST SHA-2 standards aren't yet immediately threatened, but their long-term viability is now in question. The US National Institute of Standards and Technology (NIST) has therefore begun an international competition to select a new SHA-3 standard. This...

Adi Shamir's Cube Attacks

2008-08-19 13:15:35 by schneier in Schneier on Security
 
...cryptanalytic attack called "cube attacks." He claims very broad applicability to block ciphers, stream ciphers, hash functions, etc My personal joke -- at least I hope it's a joke -- is that he's going to break every NIST hash submission without ever seeing any of them More later. (I'm sorry, but I missed the name of his student/co-author...

Speeding up WiFi Hacking with Hardware Accelerators

2008-10-14 06:25:22 by schneier in Schneier on Security
 
Elcomsoft is claiming that the WPA protocol is dead, just because they can speed up brute-force cracking by 100 times using a hardware accelerator. Why exactly is this news? Yes, weak passwords are weak -- we already know that . And strong WPA passwords are still strong. This seems like yet another blatent attempt to grab some press attention...

America's Next Top Hash Function Begins

2008-11-20 02:00:00 by Bruce Schneier in Wired Security
 
...cryptanalytic surprises. Give the community a few years to figure out which ones are good and which aren't I've previously called this sort of thing a cryptographic demolition derby: The last one left standing wins. But that's only partially true. Certainly all the groups will spend the next few years trying to cryptanalyze each other, but in...
