modelling and simulations in science and engineering and have a central role in all cryptographic protocols.<br \/>Currently pseudo random number generators (PRNG) are based on algorithms: starting from an initial input number (the seed), all the other numbers can be obtained by making the computer execute the algorithm sequentially. Although this technology is becoming increasingly less suitable due to the eventual predictability of the outputs, its implementation is extremely low cost making PRNG the current choice in cryptographic protocols.<\/p><p>However, pseudo-randomness can result in an expensive outcome if the technological advancements can decrypt communications, get access to sensitive data and tested scientific theories can give wrong predictions.<\/p><p>Recently, researchers proposed devices that harness certain features of quantum mechanics, such as Heisenberg\u2019s Uncertainty Principle, as a source of randomness. These devices are called quantum random number generators, QRNG\u2019s. Advancements in photonics produced devices able to enforce Heisenberg\u2019s Uncertainty Principle on the photons \u2013 individual particles of light -and hence obtain genuine random numbers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-32aefbf qrng pt-74 pb-82 w-799 container-1746 e-flex e-con-boxed e-con e-parent\" data-id=\"32aefbf\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-992e4b9 e-con-full col-left pr-64 e-flex e-con e-child\" data-id=\"992e4b9\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-a318b3e font-16 txt-gap-27 elementor-widget elementor-widget-text-editor\" data-id=\"a318b3e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>A common weak point of encryption protocols that can be exploited in hacker attacks, is the part of key generation, currently implemented by PRNG.<\/p><p>At Toshiba we work on QRNGs that represent a suitable solution to generate secret keys or private keys with a sufficient amount of entropy at the high speeds necessary for real-world applications. Our research explores devices with fast generation rate, compact design, tested resiliency and unpredictability<\/p><p>We have realised a QRNG based on a gain switched laser diode, developed a model to quantify its quantum phase noise, optimising the device performance and improving its security at the same time.
