Abstract:

Embedded systems are increasingly ubiquitous. Many of them have security requirements such as smart cards, mobile phones, and internet connected appliances. It can be a challenge to fulfill security requirements due to the constrained nature of embedded devices. This security challenge is worsened by the possibility of implementation attacks. Despite well formulated cryptosystems being used, the underlying hardware can often undermine any security proven on paper. If a secret key is at play, an adversary has a chance of revealing it by simply looking at the power variation. Additionally,

Abstract:

The cryptographic algorithms are designed to be mathematically secure; however, side-channel analysis attacks go beyond mathematics by taking measurements of the device’s electrical activity to reveal the secret data of a cipher. These attacks also go hand in hand with fault analysis techniques to disclose the secret key used in cryptographic ciphers with even fewer measurements. This is of practical concern due to the ubiquity of embedded systems that allow physical access to the adversary such as smart cards, ATMs, etc.. Researchers through the years have come up with techniques to block phy

Abstract:

Non-invasive side-channel attacks (SCA) are powerful attacks which can be used to obtain the secret key in a cryptographic circuit in feasible time without the need for expensive measurement equipment. Power analysis attacks (PAA) are a type of SCA that exploit the correlation between the leaked power consumption information and processed/stored data. Differential power analysis (DPA) and leakage power analysis (LPA) attacks are two types of PAA that exploit different characteristics of the side-channel leakage profile. DPA attacks exploit the correlation between the input data and dynamic pow

Abstract:

De nos jours, les concepteurs de dispositifs cryptographiques doivent non seulement mettre en œuvre des algorithmes robustes, mais ils doivent également s'assurer qu'il n'y ait pas de fuites d'informations à travers plusieurs canaux latéraux lors de l'exécution d'un algorithme. En effet, si ce n'est pas le cas, les implémentations cryptographiques, tant symétriques qu'asymétriques, seront vulnérables aux attaques par canaux auxiliaires. Pour les algorithmes à clé publique tels que le RSA, l'opération principale que doit être rendue robuste est l'exponentiation modulaire sur un anneau fini. Les

This PhD thesis focuses on the study, the hardware design, the theoretical and practical validation, and eventually the comparison of different arithmetic operators for cryptosystems based on elliptic curves (ECC).

In the case of ECC, we want to protect the secret key, a large integer, used in the scalar multiplication. Our protection methods use representations of numbers, and behaviour of algorithms to make more difficult some attacks. For instance, we randomly c

As Moore`s law continues to reduce the cost of computation at an exponential rate, embedded computing capabilities spread to ever-expanding application scenarios, such as smartphones, the Internet of Things, and automation, among many others.

Abstract:

Non-invasive side-channel attacks (SCAs) are potent attacks on a cryptographic circuit that can reveal its secret key without requiring lots of equipment. EM side-channel leakage is typically the derivative of the power consumption profile of a circuit. Since the fluctuations of the supply voltage strongly depend on the topology and features of the power distribution network (PDN), design of the PDN has a direct impact on EM side-channel leakage signature. In this thesis, we explore the security implications of distributed on-chip voltage regulators against EM side-channel attacks. Extensive H

Abstract:

Side-channel attacks are a prominent threat to the security of cryptographic implementations. Differently from the traditional black-box attacks, which exploit the inputs and outputs of cryptographic schemes, side-channel attacks partially access the inner working of the scheme as well, by observing the physical leakage emitted by the device executing cryptographic algorithms. A notable example is the class of power-analysis attacks, which exploits the power consumption of the underlying device to recover the secret keys of the implemented cryptosystem.

Abstract:

Elliptic curve cryptography (ECC) has played a signiﬁcant role on secure devices since it was introduced by Koblitz and Miller more than three decades ago. The great demand for ECC is created by its shorter key length while it provides an equivalent security level in comparison to previously introduced public-key cryptosystems (e.g.RSA). From an implementation point of view a shorter key length means a higher processing speed, smaller power consumption, and silicon area requirement. Scalar multiplication is the main operation in Elliptic Curve Diﬃe-Hellman (ECDH), which is a key-agreement pro

The approach is that the scalar is divided into two components, and then the computation cost can be further reduced by using the pre-computed table. Therefore, our countermeasure is secure and efficient.
