Phil Karn

from Wikipedia, the free encyclopedia

Philip R. Karn (born October 4, 1956 in Baltimore ) is an American electrical engineer .

Karn studied electrical engineering at Cornell Universities ( Bachelor 1978) and Carnegie Mellon ( Master 1979). He then worked at Bell Laboratories until 1991 , and since then at Qualcomm in San Diego .

The Karn algorithm he developed estimates the packet cycle time for the Transmission Control Protocol (TCP) and has received an award from the Association for Computing Machinery . In addition, Karn participated in several Request for Comments . He also wrote the KA9Q software, which is used for serial data transmission , and implemented a new transmission method with forward error correction for telemetry on the amateur radio satellites OSCAR 40 and ARISSat-1 .

In the 1990s, he complained against the American ITAR -Exportrestriktionen for the source code of the programs in the book Applied Cryptography by Bruce Schneier have been published. The restrictions were lifted during President Bill Clinton's trial .

Karn is a radio amateur with the callsign KA9Q.
