Matt Blaze

Matt Blaze is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Matt Blaze rather than just read about it. In short: Matt Blaze is an American researcher who focuses on the areas of secure systems, cryptography, and trust management. He is currently the McDevitt Chair of Computer Science and Law at Georgetown University, and is on the board of directors of the Tor Project.

Key takeaways

  • Matt Blaze belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Matt Blaze to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Matt Blaze from memory before moving on to harder problems.

Reference excerpt

Matt Blaze is an American researcher who focuses on the areas of secure systems, cryptography, and trust management. He is currently the McDevitt Chair of Computer Science and Law at Georgetown University, and is on the board of directors of the 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 lengths. After leaving Bell, Blaze was an associate professor of computer and information science at the University of Pennsylvania from 2004 to 2018. Blaze has noted a long-term conflict with the university's locksmith over his master key & safecracking publications. He then joined the faculty at Georgetown University, on a joint appointment at Georgetown Law and the department of computer science. In 2015, Blaze was part of a team of proponents that included Steven M. Bellovin, J. Alex Halderman, Nadia Heninger, and Andrea M. Matwyshyn who successfully proposed a security research exemption to Section 1201 of the Digital Millennium Copyright Act. In July 2016, the complete board of the Tor Project resigned and announced a new board, including Matt Blaze. In 2018, cryptocurrency company Monaco paid Blaze an undisclosed amount for the rights to the domain Crypto.com. Blaze had registered the domain in 1993 and sellers have estimated that the value of the domain was US$5–10 million.

Worked examples

Example 1 — a first encounter with Matt Blaze

Start with the simplest possible case. Write down what Matt Blaze claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Matt Blaze before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Matt Blaze ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Matt Blaze

In research
Matt Blaze appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Matt Blaze in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Matt Blaze is common in secondary-school and first-year university syllabi. It links to neighbouring topics American computer security academics, Columbia Graduate School of Arts and Sciences alumni, Cypherpunks, so understanding it makes those chapters shorter.
In everyday life
Look for Matt Blaze outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
