Lowell Frazer Lowell Frazer Dr. Lowell K. (Jim) Frazer was a mathematician who worked for the National Security Agency (NSA) in the field of cryptography. "Dr. Lowell K. ("Jim") Frazer founded modern cryptographic evaluation for the US government. 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. He was selected as the first Communications Security (COMSEC) mathematician assigned as
