Professor and Chair
Department of Computer Science and
New BA in IT Program Underway
The new BA in Information Technology is off to a great start with a
total of 34 students as of the beginning of the Fall semester. We
expect that number to grow quickly into the Spring and Fall of 2009.
It is already very popular at the area community colleges, and our
advisors are burning up the road as they make recruiting visits and
presentations based on requests. The word is spreading quickly!
New courses are being offered each semester. Some of these courses are
also available as electives for Computer Science and Computer
Engineering students. For example, CSCE 3055 IT Project Management is
being offered in the Spring of 2009 and requires only CSCE 2050 as a
prerequisite. Consider some of these courses for your electives.
Currently we have a large number of new students at the UNT Dallas
Campus enrolling in this new program and attending classes with their
Denton counterparts via video conference.
We also have a new faculty member dedicated to the IT program at the
Dallas campus. Afrin Naz is an Assistant Professor and Program
Coordinator for the Information Technology Program on the UNT Dallas campus.

News for Alumni
Steve Crozier was among the first group of students to graduate from
UNT's then-nascent undergraduate program in Computer Science. At UNT
from 1976 to 1980, he was fortunate to be mentored by professors
Denis Conrady, Tom Irby, Don Retzlaff, taken under the wing of then
graduate student Sharon Perkins, and guided by the wonderful Dan
Scott and Jim Poirot, chairmen of the department while he was there.
It was a wonderful time in the history of computer science and of
UNT's program. It was also a great time for music, and Steve studied
piano with Dr. Jack Roberts (deceased), then the head of the piano
department in the School of Music.
Since graduating UNT in 1980, Steve Crozier has been a technology
innovator and entrepreneur. His first major project was as an
employee of Sun Information Services (then, the computing arm of oil
company Sun Company). As a recent graduate, he wrote SunRPF (Sun
Remote Printing Facility) a 25,000 line IBM 360 assembly language
(look it up in the history books) program to control remote printing
for Sun's network of 2000 remote workstations. An entrepreneurial
opportunity came up, and Crozier formed his first company,
Crozier-Smith, Inc. Its first contract was in supporting SunRPF for
companies like General Motors, Sikorsky Aircraft, and Los Alamos
Since starting Crozier-Smith at the age of 23, Crozier has never
strayed from the entrepreneurial path. His ventures have employed
hundreds of people and spawned new market segments. He's also been
the technical brains behind innovations in remote computing, higher
education administrative software, early multi-user database systems,
4GL development tools, web content management, and technical training.
He founded or co-founded four companies: Applied Collegiate Systems
(now part of Diebold, Inc.), Populi, Luminant Worldwide--which went
public in 1998 as a market leader in full-service IT, Internet, and
Web professional services--and Black White Read, LLC.
At age 45, after a nostalgic Denton lunch with Dr. Irby and Don Retzlaff,
Crozier returned to school to get back to programming, and received a
graduate degree in molecular biophysics from University of Texas
Southwest Medical Center. His work involved the creation of a
massively parallel hardware and software architecture for the
analysis of protein and RNA structure.
But the entrepreneurial bug was too strong: Crozier is currently the
President of Black White Read, which as developed a web-based
publishing and ad serving system for online community newspapers
(using Ruby on Rails). The publishing system has been licensed by the
Presbyterian Church nation-wide, and Black White Read is developing a
franchise model to publish online community newspapers, of which
there are currently six online in the east Dallas area (see http://blackwhiteread.com.
Crozier currently lives in Dallas with his wife, Donna Persaud, MD,
who is the Pediatric Medical Director for Parkland Health and
Hospital System. Their two daughters are in college.

this "Professor for a Day" program.
Still Calling All Alumni
The CSE department at UNT would like your thoughts and suggestions
about how we can build a strong network of alumni. The department of
CS (and now CSE) existed for more than 30 years with a large number
of graduates. We would really like you to actively participate in the
departmental activities and take an active role in shaping its future.
We are thinking about a short retreat to create a networking among
alumni and seeking feedback from you. One option would be start the
event on a Friday afternoon and wrap up by Saturday evening, but you
are welcome to suggest other options.
We will set aside time for you to network with other graduates. We
will have brainstorming sessions on what is important to you. We will
have several small groups working on different issues that will have
an impact on the department's future. We want to hear if you would be
interested in participating in such an activity, and if you would be
willing to help us with the event. Please let us know by emailing
your thoughts to Genene Murphy (email@example.com).
We want to hear from you! What have you been doing since graduating from UNT?
Please send a few paragraphs and a picture to AlumniFocus@cse.unt.edu.
Ping Yu Defends her Dissertation
|Ping Yu with Dr. Tate|
Ping Yu defended her dissertation, “Direct Online/Offline Digital
Signature Schemes,” on Monday, October 20, 2008. Her major professor
was Dr. Stephen R. Tate. Other members on her committee were Dr. Ram
Dantu, Dr. Armin R. Mikler, and Dr. Ian Parberry.
This dissertation introduces new techniques for online/offline
signing, applies those in a variety of ways for creating
online/offline signature schemes, and produces five different
online/offline signature schemes that are proved secure under a
variety of models and assumptions. Two of the five schemes have the
best offline or best online performance of any currently known
technique, and are the most efficient techniques for embedded device
authentication and bursty server authentication, respectively.
