libecc is a software library for elliptic curves based cryptography (ECC), with an API supporting signature algorithms specified in the ISO14888-3 standard.
Advanced usages of this library also include the possible implementation of elliptic curve based Diffie-Hellman protocols as well as any algorithm on top of prime fields based elliptic curves (or prime fields, or rings of integers).
The presentation will introduce the rationale behind the development of libecc, as well as its architecture. Compared to other cryptographic libraries providing similar features, the differentiating points are a focus on code simplicity, portability, and auditability (self-contained and pure C99 code); a clean layer separation for all needed mathematical abstractions and operations; and a security over performance motivation (with endeavour to offer decent throughput in addition to moderate RAM and ROM memory footprints).
Though some efforts have been made to have (most of) the core algorithms constant time, turning libecc into a library shielded against side-channel attacks (SCA) is still a work in progress. The choices that have been made to resist against SPA and DPA will be contextualized and discussed.
Finally, concrete examples of libecc integration in both internal and external projects will be examined.

    Data-centric applications such as artificial intelligence and the Internet of Things (IoT) impose increasingly stringent demands on the performance, the security and the energy efficiency of modern computing architectures. Traditional approaches are often unable to keep pace with these requirements making necessary to explore innovative paradigms such as in-memory computing. This paradigm is[…]

    Since the 1970s, the complexity of systems on a chip has grown significantly. In order to improve system performance, manufacturers are integrating an increasing number of heterogeneous components on a single silicon chip. The incorporation of these components renders SoCs highly versatile yet significantly complex. Their multipurpose nature makes them suitable for use in a variety of domains,[…]

    Ring oscillators (ROs) are often used in true random number generators (TRNGs). The jitter of their clock signal, used as a source of randomness, stems from thermal and flicker noises. While thermal noise jitter is often identified as the main source of randomness, flicker noise jitter is not taken into account due to its autocorrelated nature which greatly complexifies modelling. However, it is a[…]

    Hardware Trojan Horses that are software-exploitable can be inserted into microprocessors, allowing attackers to run unauthorized code or escalate privileges. Additionally, it has been demonstrated that attackers could observe certain microprocessor features - seemingly unrelated to the program's execution - to exfiltrate secrets or private data. So, even devices produced in secure foundries could[…]

    The threat of Hardware Trojan-based Covert Channels (HT-CCs) presents a significant challenge to the security of wireless communications. In this work, we generate in hardware and make open-source a dataset for various HT-CC scenarios. The dataset represents transmissions from a HT-infected RF transceiver hiding a CC that leaks information. It encompasses a wide range of signal impairments, noise[…]

    With the widespread development of artifical intelligence, Deep Neural Networks (DNN) have become valuable intellectual property (IP). In the past few years, software and hardware-based attacks targetting at the weights of the DNN have been introduced allowing potential attacker to gain access to a near-perfect copy of the victim's model. However, these attacks either fail against more complex[…]
