Matt Blaze is a researcher in the areas of secure systems, cryptography, and trust management. He is currently an Associate Professor[3] of Computer and Information Science at the University of Pennsylvania, and on the board of directors of the Tor Project.[4]
Work
Blaze received his PhD in Computer Science from Princeton University.
In 1992, while working for AT&T, Blaze implemented a strong cryptographic package known as "CFS", the Cryptographic File System, for Unix, since ported to Linux.[5] CFS uses Network File System as its transport mechanism, allowing users to encrypt selected directory hierarchies, but mount them unencrypted after providing the key. In November, 1993, he presented a paper on this project, "A Cryptographic File System for Unix", at the 1st ACM Conference on Computer and Communications Security.[6] Blaze also published a paper "Key Management in an Encrypting File System", in the Proceedings USENIX Summer 1994 Technical Conference.
In the early 1990s, at the height of the "crypto war", Blaze was a participant in the Cypherpunks mailing list[7] and in 1994, he found a critical weakness in the wiretapping mechanisms of the Clipper chip.[2] His paper, Protocol Failure in the Escrowed Encryption Standard,[8] pointed out that the Clipper's escrow system had a serious vulnerability: a brute-force attack could allow the Clipper chip to be used as an encryption device, while disabling the key escrow capability.[8][9][10] Later during this time, he was one of the authors of a seminal paper on calculating secure key lengths.[11]
In July 2016, the complete board of the Tor Project resigned and announced a new board, including Matt Blaze.[12][13]
In 2018, crypto Visa card company Monaco paid Blaze an undisclosed amount for the rights to the domain Crypto.com.[14]
