'''Matt Blaze''' is a researcher in the areas of secure systems, [[cryptography]], and [[trust management (information system)|trust management]]. He is currently an Associate Professor of Computer and Information Science at the [[University of Pennsylvania]], and on the board of directors of the [[The Tor Project, Inc|Tor Project]].

==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. 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. 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]] and in 1994, he found a critical weakness in the wiretapping mechanisms of the [[Clipper chip]].
His paper, ''Protocol Failure in the Escrowed Encryption Standard'', 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. Later during this time, he was one of the authors of a seminal paper on calculating secure [[key length]]s.

In 2003, Blaze independently rediscovered, and published, a serious vulnerability in "master key" security in physical locks. Although apparently an open secret among some professional [[locksmithing|locksmiths]]; his decision to [[Full disclosure (computer security)|disclose it publicly]] provoked some controversy.

In July 2016, the complete board of the [[Tor Project]] resigned and announced a new board, including Matt Blaze.
