Gilles Van Assche

Gilles Van Assche is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gilles Van Assche rather than just read about it. In short: Gilles Van Assche is a Belgian cryptographer who co-designed the Keccak cryptographic hash, which was selected as the new SHA-3 hash by NIST in October 2012. The SHA-3 standard was released by NIST on August 5, 2015.

Key takeaways

Gilles Van Assche belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gilles Van Assche to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gilles Van Assche from memory before moving on to harder problems.

Reference excerpt

Gilles Van Assche is a Belgian cryptographer who co-designed the Keccak cryptographic hash, which was selected as the new SHA-3 hash by NIST in October 2012. The SHA-3 standard was released by NIST on August 5, 2015. In 1998 Van Assche graduated from Université libre de Bruxelles (ULB) with a Physics Engineer degree. He then went to work for STMicroelectronics while also working on his PhD thesis at the Center for Quantum Information and Communication at the ULB. His PhD thesis was directed by Pr. Nicolas Cerf where he researched quantum key distribution (QKD) and related classical information theory problems such as secret-key distillation, reconciliation and privacy amplification. His thesis was later expanded into a book, "Quantum Cryptography and Secret-Key Distillation" published by Cambridge University Press on 29 June 2006. Along with Joan Daemen and Michaël Peeters he designed the NOEKEON family of block ciphers which were submitted to the NESSIE project in September 2000. In 2006 Guido Bertoni joined the team and together they designed the RadioGatún hash function and stream cipher, introduced the concept of cryptographic sponge functions and designed the Keccak sponge function which later became the SHA-3 standard. He currently works in the Secure Microcontrollers Division of STMicroelectronics in Diegem, Belgium and teaches cryptography at the École Supérieure d'Informatique as well as the Université libre de Bruxelles in Brussels.

Worked examples

Example 1 — a first encounter with Gilles Van Assche

Start with the simplest possible case. Write down what Gilles Van Assche claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gilles Van Assche before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gilles Van Assche ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gilles Van Assche

In research: Gilles Van Assche appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gilles Van Assche in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gilles Van Assche is common in secondary-school and first-year university syllabi. It links to neighbouring topics Belgian cryptographers, Belgian scientist stubs, European mathematician stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Gilles Van Assche outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
