Mihir Bellare

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.
