Mihir Bellare

Mihir Bellare 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 Mihir Bellare rather than just read about it. In short: Mihir Bellare is a cryptographer and professor at the University of California San Diego. He holds a Bachelor of Science degree from the California Institute of Technology and a Ph.D. from the Massachusetts Institute of Technology.

Key takeaways

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

Reference excerpt

Mihir Bellare is a cryptographer and professor at the University of California San Diego. He holds a Bachelor of Science degree from the California Institute of Technology and a Ph.D. from the Massachusetts Institute of Technology. He has published several seminal papers in the field of cryptography (notably in the area of provable security), many of which were co-written with Phillip Rogaway. Bellare has published a number of papers in the field of Format-Preserving Encryption. His students include Michel Abdalla, Chanathip Namprempre, Tadayoshi Kohno and Anton Mityagin. Bellare is one of the authors of skein. In 2003 Bellare was a recipient of RSA Conference's Sixth Annual Award for outstanding contributions in the field of mathematics for his research in cryptography. In 2013 he became a Fellow of the Association for Computing Machinery. In 2019 he was awarded Levchin Prize for Real-World Cryptography for his outstanding contributions to the design and analysis of real-world cryptosystems, including the development of random oracle model, modes of operation, HMAC, and models for key exchange. Bellare's papers cover topics including:

HMAC Random oracle OAEP Probabilistic signature scheme Provable security Format-preserving encryption Authenticated encryption Garbled circuits Multi-signatures Forward-secure digital signatures Threshold signatures Deterministic encryption Searchable encryption Hedged public-key encryption Related-key attacks Group signatures Key-dependent message security Message-locked encryption and secure deduplication Ratcheted encryption Identity-based encryption Non-malleable encryption Proofs of knowledge Pseudorandom functions CBC MAC security Code-based game-playing proofs Concrete security of symmetric encryption Algorithm-substitution attacks Authenticated key exchange Blind signatures Incremental cryptography Secret sharing Obfuscation OCB mode of operation Probabilistically checkable proofs Zero-knowledge proofs Fiat-Shamir transform Password-based encryption Multi-user security Robust encryption Universal Computational Extractors (UCE) Big-key cryptography Chameleon hash functions Wiretap channel Functional encryption Electronic payment systems Batch verification

On September 14, 2022, Bellare was appointed by the mayor of San Diego to the city's Privacy Advisory Board.

Worked examples

Example 1 — a first encounter with Mihir Bellare

Start with the simplest possible case. Write down what Mihir Bellare 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 Mihir Bellare 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 Mihir Bellare 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 Mihir Bellare

In research: Mihir Bellare 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 Mihir Bellare 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: Mihir Bellare is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer scientist stubs, Fellows of the Association for Computing Machinery, International Association for Cryptologic Research fellows, so understanding it makes those chapters shorter.
In everyday life: Look for Mihir Bellare 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.
