Phillip Rogaway

Phillip Rogaway 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 Phillip Rogaway rather than just read about it. In short: Phillip Rogaway (also referred to as Phil Rogaway) is an American cryptographer and former professor of computer science at the University of California, Davis. He graduated from Beverly Hills High School, and later earned a BA in computer science from UC Berkeley and completed his PhD in cryptography at MIT, in the Theory of Computation group.

Key takeaways

Phillip Rogaway 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 Phillip Rogaway to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Phillip Rogaway from memory before moving on to harder problems.

Reference excerpt

Phillip Rogaway (also referred to as Phil Rogaway) is an American cryptographer and former professor of computer science at the University of California, Davis. He graduated from Beverly Hills High School, and later earned a BA in computer science from UC Berkeley and completed his PhD in cryptography at MIT, in the Theory of Computation group. He has taught at UC Davis since 1994. He was awarded the Paris Kanellakis Award in 2009 and the first Levchin Prize for Real World Cryptography in 2016. Rogaway received an NSF CAREER award in 1996, which the NSA had attempted to prevent by influencing the NSF. He has been interviewed in multiple media outlets regarding his stance on the ethical obligations that cryptographers and computer scientists have to serve to the public good, specifically in the areas of internet privacy and digital surveillance. Rogaway's papers cover topics including:

CMAC Concrete security DES and DES-X Format-preserving encryption OCB mode Random oracle model SEAL UMAC Zero-knowledge proofs

Worked examples

Example 1 — a first encounter with Phillip Rogaway

Start with the simplest possible case. Write down what Phillip Rogaway 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 Phillip Rogaway 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 Phillip Rogaway 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 Phillip Rogaway

In research: Phillip Rogaway 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 Phillip Rogaway 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: Phillip Rogaway is common in secondary-school and first-year university syllabi. It links to neighbouring topics American cryptographers, Cryptographer stubs, International Association for Cryptologic Research fellows, so understanding it makes those chapters shorter.
In everyday life: Look for Phillip Rogaway 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.
