Boffins achieve 'breakthrough' in random number generation

Another brilliant explanation from the Reg

Cryptographic algorithms attempt to keep information secret by transforming it into a stream of random numbers, making it unintelligible. These numbers, however, are not truly random since the algorithm uses a predetermined set of mathematical formulae to generate these numbers, so the information can be breached.

Wow. There is almost nothing correct in that entire paragraph.

While this paper mentions cryptographic applications of multiple-source extractors, those applications do not include "transforming [plaintext] into a stream of random numbers", except in the most tenuous sense - and that's if we gloss "random" as "pseudorandom". And "a predetermined set of mathematical formulae" is just an awkward definition for an algorithm, so that whole clause is tautological. And "the information can be breached", insofar as it means anything at all, is obvious; encryption is defined by the possibility of decryption.
