<p>Researchers from the University of Maryland have devised a new kind of random number generator that is cryptographically secure, inherently private and — most importantly — certified random by the laws of physics. Randomness is important, particularly in the age of the Internet, because it guarantees security. Valuable data and messages can be encrypted using long strings of random numbers to act as "keys", which encode and decode the information. Randomness implies unpredictability, so if the key is truly random, it's next to impossible for an outsider to guess it.</p>

<p><i>In <a href="/issue34/features/ekert/index.html">Cracking codes, part I</a> in the previous issue of Plus, we saw how the desire to communicate secretly has inspired human ingenuity to create intricate ciphers - and how the desire to learn others' secrets led to those ciphers being broken. We now leave mathematics, and enter the world of quantum physics for an introduction to the
peculiar phenomenon of quantum correlation - a phenomenon that evades all common explanations.</i></p><p><a href="https://plus.maths.org/content/cracking-codes-part-ii" target="_blank">read more</a></p>https://plus.maths.org/content/cracking-codes-part-ii#comments35action at a distancecipherlocal realismquantum cryptographyquantum entanglementSat, 30 Apr 2005 23:00:00 +0000plusadmin2267 at https://plus.maths.org/content
