Sylvain Guilley – författare

This book constitutes the proceedings of the Third International Conference on Codes, Cryptology and Information Security, C2SI 2019, held in Rabat, Morocco, in April 2019.

The 19 regular papers presented together with 5 invited talks were carefully reviewed and selected from 90 submissions. The first aim of this conference is to pay homage to Said El Hajji for his valuable contribution in research, teaching and disseminating knowledge in numerical analysis, modeling and information security in Morocco, Africa, and worldwide. The second aim of the conference is to provide an international forum for researchers from academia and practitioners from industry from all over the world for discussion of all forms of cryptology, coding theory, and information security.

This book offers the reader a formalization, characterization and quantification of the real threat level posed by side-channel leaks from devices implementing cryptography. It exploits the best mathematical tools for quantifying information leakage and characterizing leakage-based attacks. The two possible approaches are described in detail. This includes the optimal attack strategy that can be derived (in specific contexts) or generic bounds regarding data complexity that can be computed. The tone of this book is essentially mathematical. It aims to establish formal foundations for techniques that are otherwise used as engineering recipes in industrial laboratories or empirical intuitions for deriving security levels from practical implementations. It is a systematization of knowledge and a compilation of relevant tools relating to the practice of side-channel analysis on embedded systems.

This book provides an up-to-date and improved analysis and understanding of embedded devices that conceal secrets that can be extracted by an attacker. Typical attacks involve measuring the device''s power consumption or radiated electromagnetic field.  As a source of noisy information, this correlates it with secrets and enabling these secrets to be retrieved.  The attacker in some cases, can purchase a blank device from the same series and learn about its leakage, particularly how it relates to the secrets. This book also covers how such information can enhance hardware attacks deployed on another device.

Researchers and engineers working in the field of side-channel security for embedded systems and related countermeasures as well as hardware and software engineers focused on implementing cryptographic functionalities will want to purchase this book as a reference. Advanced-level students majoring in computer science and electrical engineering will find this book valuable as a secondary textbook.

The 31 revised full papers including two invited talks presented in this volume were carefully reviewed and  selected from 61 submissions. The papers are organized in topical sections such as network security, threat analysis, application security, cryptographic. Protocols,  cryptanalysis, cryptographic implementations, authentication using bio and ML, authentication, ICT Convergent security

The 17 papers presented in this volume were carefully reviewed and selected from numerous submissions. They were organized in topical sections named: Side-Channel Attacks and Technological Effects; Side-Channel Countermeasures; Algorithmic Aspects in Side-Channel Attacks; Side-Channel Attacks; Fault Attacks; Embedded Security; and Side-Channel Tools.
