# Mihir Bellare

**Mihir Bellare** is a cryptographer and professor at the University of California San Diego. 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's Sixth Annual Conference Award for outstanding contributions in the field of mathematics for his research in cryptography.[1] In 2013 he became a Fellow of the Association for Computing Machinery.[2] 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.[3]

Bellare's papers cover topics including:

- HMAC
- Random oracle
- OAEP
- Probabilistic signature scheme
- Provable security
- Format-preserving encryption

Bellare's work is slated to be used in Bitcoin.[4]
