Talk:David Chaum

Backup copy
David Chaum is the inventor of many cryptographic protocols, including blind signature schemes, commitment schemes, and ecash. In 1982, Chaum founded the International Association for Cryptologic Research (IACR), which currently organizes academic conferences in cryptography research. He has contributed to the industry advancement of electronic cash, partially in his role as founder of DigiCash, an electronic cash company, in 1990.

Chaum gained a doctorate in Computer Science and Business Administration from the University of California, Berkeley. Subsequently, he taught at the New York University Graduate School of Business Administration and at the University of California. He is currently a visiting professor at K.U. Leuven.

His contributions to cryptography include the invention of two anonymity networks: mix networks (the basis for virtually all modern anonymity networks) and DC-Nets; silo watching techniques; invention of several important digital signatures: blind signatures, undeniable signatures, unconditionally secure signatures, and group signatures; tamper-safing sensor systems (foreshadowing many concepts in side-channel cryptanalysis); various techniques for anonymous credentials, invention of partial key techniques (a predecessor to threshold encryption); first techniques for anonymous digital transactions and the invention of ecash; early zero-knowledge proof techniques; multiparty computations; and the invention of cryptographic voting. He also performed notable cryptanalysis of DES and the RSA signature scheme.

Currently, Chaum heads the Punchscan and Scantegrity projects — open-source, end-to-end auditable voting initiatives based on cryptographic principles.

I'm not sure where to put it, but certainly his xx.network coin should be mentioned somewhere, and it's early name, Privategrity.

It seems his groundbreaking work made VPNs possible. Setenzatsu.2 (talk) 19:56, 28 May 2024 (UTC)
