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 1993, Blaze published (with John Ioannidis) a paper presenting a protocol ("swIPe") that was to be one of the forerunners of IPsec . In 1994, he found a means to circumvent the wiretapping mechanisms of the Clipper chip, contributing to the death of this government-sponsored initiative. In 2003, he independently rediscovered a serious vulnerability in "master key" security in physical locks that was an open secret among locksmiths; his decision to disclose it publicly provoked controversy.

Blaze coined the term trust management to refer to the policy system which decides whether a particular entity should be permitted to carry out a particular action, and has provided foundation research in this area.
