# Dr. Lowell K. Frazer

##                 2003 Hall of Honor Inductee            

Dr. Lowell K. ("Jim") Frazer founded modern cryptographic evaluation. As a result of his efforts, all cryptography used for classified applications by the U.S. Department of Defense and Intelligence Community is now subject to rigorous scientific evaluation. He influenced the design of most U.S. cryptographic systems fielded prior to 1990. In addition, Dr. Frazer was a prolific writer of technical papers.

His college career at Indiana University was interrupted by the world war; he received his Ph.D. in 1951. Shortly after, Dr. Frazer went to work for what is now NSA.

He was selected as the first Communications Security (COMSEC) mathematician assigned as an integrated member at GCHQ from 1954 to 1956. During this two-year tour, he performed assessments on many cryptographic systems, designed speech cryptosystems, and discovered an analytic technique that would be widely used over the next three decades. Also, he authored a training primer for new COMSEC cryptomathematicians.

Dr. Frazer was the principal formulator of standards the U.S. and the UK use to judge the strength of cryptographic systems. He continued to lead the adaptation and extension of those standards as the role of cryptography grew from COMSEC to a more diverse mission.

Under his leadership, the industrial TEMPEST program, a novel approach to government-industry interaction, matured. The program integrated TEMPEST concerns into the security evaluation process for U.S. cryptographic equipment.

Dr. Frazer played a major role in developing NSA's mathematics, cryptanalysis and Information Assurance (IA) communities. He assisted in developing the National Cryptologic School and was associated with the CryptoMath Institute from its inception. He was a member of the Mathematics, Cryptanalysis, and COMSEC Career Panels, and an Advisor to the NSA Technical Journal for approximately 20 years.

Dr. Frazer received numerous awards throughout his career including the Agency's Meritorious Civilian Service Award in 1969, the Exceptional Civilian Service Award in 1981, and the DCI's National Intelligence Distinguished Service Medal in 1985. Dr. Frazer passed away in December 2013.
