Cybercriminalité vs Understanding Cryptography: Which Should You Read?

Two cybersecurity books on Foundations, compared honestly: who each is for, what each does best, and which to read first.

Cybercriminalité

Comprendre, prévenir, réagir

Solange Ghernaouti

Solange Ghernaouti's structured treatment of cybercrime — how it works, how to prevent it, how to respond — spanning technical, legal and organisational angles.

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

Students (law, management, engineering), managers and investigators who want a structured, up-to-date overview of cybercrime across technical, legal and human dimensions.

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

Practitioners wanting forensic or offensive technique; like Ghernaouti's other work, it's a structured survey, not a hands-on manual.

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

A 2023 structured survey of cybercrime spanning technique, law and prevention — broad rather than deep.
Strong on the legal and organisational response that purely technical books skip.
A natural companion to Ghernaouti's Cybersécurité, focused on the criminal dimension.

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

We rate Understanding Cryptography higher (4/5 against 3/5 for Cybercriminalité). For most readers, that means Understanding Cryptography is the primary pick and Cybercriminalité is a useful follow-up.

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

Cybercriminalité and Understanding Cryptography both cover Foundations, so reading them in sequence reinforces the same material from different angles.
