New world record.

Japanese researchers were able to overcome existing unbreakable
encryption in 148 days
923-bit encryption was thought to be invincible, experts assumed that it
would at best take several hundreds of thousands of years to crack the
code. Now it's done. 148 days and a few hours as well as 21 computers is
the cryptographers of Fujitsu Laboratories, the National Institute of
Information and Communications Technology (NICT) and Kyushu University
in Japan. That they may have broken the world record for cryptanalysis
cryptography to the next generation.
Helpful for standardization
The Fujitsu Laboratories write in a press release that it had been made
in the development of many failures, until the pairing-based
cryptography that length have been found to be vulnerable and could be
cracked in 148.2 days. The decoding of the pairing-based cryptography
bring authorities responsible for the standardization helpful insights,
writes Fujitsu. The coupling-based encryption is standardized and can be
used for identity-based, keyword-searching and functional encryption.
That would not have worked with the predecessor of the "public key"
encryption.
Help for businesses and governments
The researchers believe that to help them through the deciphering of
codes companies, governments and organizations understand the need to be
sure their electronic information. "We have shown for the first time
that cryptography with these parameters is fragile and can be broken up
with a realistic amount of time," writes Fujitsu. Compared to the
previous world record, the researchers of the NICT and the Future
University Hakodate, with 204 digits (676 bits) occupied was needed for
the current computing performance, which is several hundred times
higher. (Red, derStandard.at, 06/21/2012)
