Towards Better Security in True Random Number Generation
Abstract: True random number generators (TRNGs) are essential in cryptography. They are used to generate cryptographic keys, but also nonces (numbers used once), padding values, and masks in countermeasures against side-channel attacks. Designing a good TRNG remains a challenge, starting with the choice of a robust physical source of randomness, selection of the randomness extraction method, the in-depth analysis of the principle and continuing with the design and verification of the parameterized stochastic model ensuring the high level of entropy and or the dedicated online tests based on the model. We will illustrate this TRNG development process on many positive and negative examples.
Bio: Viktor Fischer is an emeritus professor at Jean Monnet University in Saint-Etienne, France and part-time professor at Czech Technical University in Prague, Czech republic. His research interests include security of cryptographic embedded systems and in particular of random number generators aimed at cryptographic applications.
