Almost twice as fast as SHA-512 and three times faster than SHA-256.
Skein is a new family of cryptographic hash functions. Its design combines speed, security, simplicity, and a great deal of flexibility in a modular package that is easy to analyze.
Skein is fast.
Hopefully it is also cryptographically secure.
Bletchley Park to close?

In 2000 I visited what is probably one of the most interesting attractions for geeky history buffs in the UK: Bletchley Park.
Even back when I visited it, the Park was in a dismal state, badly preserved, run down — definitely far from what it should be, given both the fact that sixty years ago it was a British Government secret installation and its immense importance in World War II — and all that in a country whose culture even today is still fundamentally affected (I’d dare say defined) by the two World Wars. Today, about 8 years since my visit to Bletchley Park, I read at Bruce Schneier’s blog that it may close in a few years due to lack of funds. Having grown up in Hellas, a country with a long history and thousands of ancient sites all over the country, I always thought that the dismal state of Hellenic antiquities was due to the country’s deeply rooted nepotism, corruption, stupidity, indifference and total incapacity for efficient, constructive work. While the British government has quite frequently showed that it’s not far from the Hellenic one, one would expect that they’d care more to preserve a small-ish park and a Victorian mansion.
If you appreciate 20th century history and/or cryptography and are visiting the UK (or, better yet, live there), pay a visit to Bletchley Park. The tour may be somewhat indifferent to many, the park itself may be run down, but you’d be seeing first hand the place where Enigma was systematically deciphered during the war and — through your purchase of a ticket and or other souvernirs or donations — will help preserve a piece of modern history. Finally for all those interesting in computing, Bletchley Park hosts a small, and seemingly uninteresting computer museum; this is nothing like some of its counterparts in the U.S.. Nevertheless it has a unique exhibit that’s bound to thrill every computer scientist, programmer, engineer or geek visiting it: a working replica of Colossus.
For more information about the Park go to their page here or visit its Wikipedia entry.
Robert Morris Sr. (the father of Robert Morris Jr. who made the ‘internet worm’ back in late 1988), ex. lead scientist of the NSA, is speaking at a seminar in Cambridge this Tuesday entitled “The cryptographic role of the cleaning lady”. You can get more info here
I am definitely going. :)
Update: The Morris seminar at Cambridge was quite interesting, but mostly from a ‘historical’ point of view. Nothing much on the ‘cleaning lady’ apart from a few (some well-known) stories here and there. Nothing much on anything really. A bit disappointed in that respect. But it was a nice trip out of London.
