    Random numbers are essential for modern cryptographic systems. They are used as cryptographic keys, nonces, initialization vectors and random masks for protection against side channel attacks. In this thesis, we deal with random number generators in logic devices (Field...

    With the sharp increase in the deployment and integration of the Internet of Things, one challenge is to ensure security with respect to privacy and trust issues. With billions of connected devices, there is a huge risk of unauthorized use or abuse. To protect from such...

    Abstract Random number generators (RNGs) are basic cryptographic primitives. They are used to generate cryptographic keys, initialization vectors, challenges and nonces in cryptographic protocols, and random masks in countermeasures against side channel attacks. RNGs de...

    International audience; Oscillating rings are widely used in CMOS logic devices because they are easy to integrate, require low area and low power. Their main disadvantage is that they tend to lock to each other and/or to an external periodic signal. This locking phenom...

    Implementing a cryptographic circuit poses challenges not always acknowledged in the backing mathematical theory. One of them is the vulnerability against side-channel attacks . A side-channel attack is a procedure that uses information leaked by the circuit through, f...

    © 2018 IEEE. Random number generation is a key function of today's secure devices. Commonly used for key generation, random number streams are more and more frequently used as the anchor of trust of several countermeasures such as masking. True Random Number Genera...

    In this paper, we evaluate clock signals generated in ring oscillators and self-timed rings and the way their jitter can be transformed into random numbers. We show that counting the periods of the jittery clock signal produces random numbers of significantly better qua...

    In this paper we present a novel true random number generator based on high-precision edge sampling. We use two novel techniques to increase the throughput and reduce the area of the proposed randomness source: variable-precision phase encoding and repetitive sampling. ...

    Although the Android system has been continuously hardened against side-channel attacks, there are still plenty of APIs available that can be exploited. However, most side-channel analyses in the literature consider specifically chosen APIs (or resources) in the Android...
