HardBlare, a hardware/software co-design approach for Information Flow Control
Speaker : Guillaume Hiet – Pascal Cotret
One way to increase the security level of computer systems is to rely on both software and hardware mechanisms. In this context, the HardBlare project proposes a software hardware co-design methodology to ensure that security properties are preserved all along the execution of the system but also during file storage. The HardBlare project is a multidisciplinary project between CentraleSupélec IETR[…] -

SideLine and the advent of software-induced hardware attacks
Speaker : Joseph Gravellier
In this talk, we will discuss software-induced hardware attacks and their impact for IoT, cloud and mobile security. More specifically, I will introduce SideLine, a new power side-channel attack vector that can be triggered remotely to infer cryptographic secrets. SideLine is based on the intentional misuse of delay-lines components embedded in SoCs that use external memory. I will explain how we[…] -

True Random Number Generators enabled hardware security
Speaker : Bohan Yang
True randomness is all about unpredictability, which can neither be qualified nor quantified by examining statistics of a sequence of digits. Unpredictability is a property of random phenomena, which is measured in bits of information entropy. Application of randomness spans from art to numerical computing and system security. Random numbers enable various cryptographic algorithms, protocols and[…] -

Post-Quantum Cryptography Hardware: Monolithic Implementations vs. Hardware-Software Co-Design
Speaker : Markku-Juhani Saarinen
At PQShield, we’ve developed dedicated coprocessor(s) for lattice schemes, hash-based signatures, and code-based cryptography. These cryptographic modules are commercial rather than academic and designed to meet customer specifications such as a specific performance profile or Common Criteria and FIPS security certification requirements.Hardware implementations of legacy RSA and Elliptic Curve[…] -

New uses in Symmetric Cryptography: from Cryptanalysis to Designing
Speaker : Clémence Bouvier - INRIA
New symmetric primitives are being designed to be run in abstract settings such as Multi-Party Computations (MPC) or Zero-Knowledge (ZK) proof systems. More particularly, these protocols have highlighted the need to minimize the number of multiplications performed by the primitive in large finite fields.<br/> As the number of such primitives grows, it is important to better understand the[…] -

PMNS for efficient arithmetic and small memory cost
Speaker : Fangan Yssouf Dosso - Ecole des Mines de Saint-Etienne
The Polynomial Modular Number System (PMNS) is an integer number system which aims to speed up arithmetic operations modulo a prime p. Such a system is defined by a tuple (p, n, g, r, E), where p, n, g and r are positive integers, E is a monic polynomial with integer coefficients, having g as a root modulo p. Most of the work done on PMNS focus on polynomials E such that E(X) = X^n – l, where l is[…] -
