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.

Understanding Cryptography

A Textbook for Students and Practitioners

Christof Paar, Jan Pelzl

A genuinely teachable intro to modern cryptography that derives the math instead of hand-waving it, covering symmetric and public-key primitives without drowning you in proofs.

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.

Engineers and students who want to actually understand AES, RSA, and ECC rather than just call a library, and who learn better from worked examples than from theorem-proof.

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.

Skip this if you want a security-engineering how-to. It teaches the primitives, not protocol design, key management, or how things break in production.

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 discrete logarithm problem and integer factorization are the two pillars under most deployed public-key crypto, and the book makes you compute with both.
AES is presented as understandable finite-field arithmetic, not magic, which demystifies the most-used cipher on earth.
Cryptographic security is about quantifying attacker effort, not about secrecy of the algorithm.

How they compare

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

Both books target intermediate-level readers, so the choice is about topic, not difficulty.

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