Portrait of Josh Benaloh

Josh Benaloh

Senior Cryptographer


Josh Benaloh is Senior Cryptographer at Microsoft Research, an Affiliate Faculty Member of the Paul G. Allen School of Computer Science and Engineering at the University of Washington, and spent 17 years on the Board of Directors of the International Association for Cryptologic Research. He earned his S.B. degree from the Massachusetts Institute of Technology and M.S., M.Phil., and Ph.D. degrees from Yale University where his 1987 doctoral dissertation, Verifiable Secret-Ballot Elections, introduced the use of homomorphic encryption to enable end-to-end verifiable election technologies.

Dr. Benaloh’s numerous research publications in cryptography and voting have pioneered new technologies including the “cast or spoil” paradigm that brings voters into the election verification process with minimal burden.

He has served on the program committees of dozens of cryptography and election-related conferences and workshops and is a frequent speaker on the history, development, and mechanisms behind verifiable voting.  He also served on the…
