Matt Blaze is a researcher in the areas of secure systems, cryptography, and trust management. He is currently an Associate Professor of Computer and Information Science at the University of Pennsylvania; he 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. 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.
