Japanese Break 'World Cryptography Record' With Cryptanalysis Of 278-digit Crypto

Cryptanalysis of a 278-digit (923-bit)-long pairing-based cryptography was always thought impossible, because they said it would take 100,000 years to break it. But, Japanese researchers from Fujitsu Laboratories, National Institute of Information and Communications Technology and Kyushu University have jointly made possible the impossible. They broke a world cryptography record by carrying out successful cryptanalysis of this next gen cryptography standard in just 148.2 days. The earlier record was of 204 digits (676 bits) from 2009.



As we see the rapid advancements in the field of cryptanalytic techniques and the upsurge of supercomputing power owing to superfast code-breaking, we have to remember that this signals a decrease in the level of cryptographic security. So, researchers have to keep evaluating the time period for which a certain cryptographic technology can be securely used. Since pairing-based cryptography is not much advanced at the moment, it is very early to test it against a new attack method.

The japanese researchers from these three institutes worked together to select a secure encryption method and figured out an appropriate timing to exchange a key length. They want that these secure techniques be employed at Japanese electronic government systems as well as International standardization organizations. With the upheaval of pairing-based cryptography instead of the previous public key cryptography, avenues for applications in identity-based encryption, keyword searchable encryption and functional encryption are now wide open.
