Maîtriser la cryptographie d'aujourd'hui et de demain

Des bases mathématiques aux standards post-quantiques

Mbaye Ngom

A cryptography engineer specializing in information-system security mechanisms, who also teaches the subject, builds from cryptography's mathematical foundations up to today's post-quantum standards.

Advanced

Sécurité informatique

Cours et exercices corrigés

Gildas Avoine, Pascal Junod, Philippe Oechslin, Sylvain Pasini

A rigorous academic course on the foundations of security — cryptography, authentication, access control — with corrected exercises, from a team of well-known French and Swiss cryptographers.

Read this if

French-speaking readers who want a complete progression through cryptography, from mathematical foundations to recent post-quantum standards, written by someone who teaches the subject.

University students and engineers who want the formal foundations: cryptographic primitives, protocols, authentication and access control, with worked exercises to test understanding. Oechslin (rainbow tables) and Junod give the crypto real weight.

Skip this if

Readers who want only developer-facing applied cryptography (library choice, implementation) without the mathematical grounding; this book builds understanding from the foundations rather than skipping past them.

Readers looking for practical pentesting, tooling or a gentle introduction. This is a courses-and-exercises textbook with mathematical rigour, not a hands-on hacking guide.

Key takeaways

One of the few French-language books to explicitly cover post-quantum standards, still a thin spot in the existing catalog.
Structured as a pedagogical progression, from mathematical foundations to current standards, by an author who teaches cryptography.
Fills a real gap: the catalog's existing French-language cryptography titles (La science du secret, Exercices et problèmes de cryptographie) are older or narrower in scope.

The strongest French-language treatment of the cryptographic and formal foundations of security, exercises included.
Written by serious cryptographers — Oechslin literally invented rainbow tables — so the crypto is correct and deep, not hand-waved.
Best used as a course companion; the corrected exercises are the real value over a pure narrative text.

How they compare

Maîtriser la cryptographie d'aujourd'hui et de demain and Sécurité informatique are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Maîtriser la cryptographie d'aujourd'hui et de demain is pitched at intermediate level. Sécurité informatique is pitched at advanced level. Read the easier one first if you're not yet comfortable with the topic.

Maîtriser la cryptographie d'aujourd'hui et de demain and Sécurité informatique both cover Cryptography, Foundations, so reading them in sequence reinforces the same material from different angles.
