Hellohere are more informations about the info.the paper has been presented at 
the Asiacrypt09 conference in Tokyo and is called : A Practical-Time Attack on 
the Encryption Algorithm Used in Third Generation Telephony
    Orr Dunkelman, Nathan Keller, and Adi Shamir
i couldn't find any more information or public distribution of this one. Maybe 
here http://www.joux.biz/wordpress/?p=10
but i didn't watch that video yet.Hope this could help intersted guys ;)
See u

Google returns nothing. Which conference is this, and is the paper available 
for download?

Hey all, 
according to the last conference in Tokyo last week. It appers that Dunkelman 
and Shamir found a way to break the Kasumi encryption method, and Kasumi is 
used in .... A5/3 :-D
More references to come.
bye

sure. one should sort the table before seeding it though.
i am not entirely sure whether the sorter runs correct now, so please

wait till i find some time to look over it.

If you have 720 tables, yes.

with 200 64bit samples of known plaintext you can do 200 lookups, meaning you

need 1/200 of the theoretical maximum tablesize and 200 times longer for
the lookup.

generally a good idea. when i find the time i will setup a forum.

the cipher of 3G networks is unbreakable even to the NSA working together
with the russion botnet mafia, so unless advances are made in cryptoanalyzing
A5/3 it is unbreakable currently.

currently beyond the horizon.
