'''Phil Karn''', born October 4, 1956, is an engineer from [[Baltimore, Maryland]]. He earned a bachelor's degree in [[electrical engineering]] from [[Cornell University]] in 1978 and a master's degree in electrical engineering from [[Carnegie Mellon University]] in 1979. From 1979 until 1984, Phil Karn worked at [[Bell Labs]] in [[Naperville, Illinois]], and [[Murray Hill, New Jersey]]. From 1984 until 1991, he was with Bell Communications Research in [[Morristown, New Jersey]]. Since 1991 he has been with [[Qualcomm]] in [[San Diego]], where he specializes in wireless data networking protocols, security, and cryptography.

He has been an active contributor in the [[IETF]], especially in security, but is also a strong contributor to the [[Internet]] architecture. His name is on at least 6 [[Request for comments|RFCs]]. He is the inventor of [[Karn's Algorithm]], a method for calculating the round trip time for IP packet retransmission.

He is well known in the amateur radio community for his work on the [[KA9Q]] [[Network Operating System]] (NOS), named after his amateur [[callsign]], early 9600 bit/s FSK radio modems, and more recently, the introduction of [[forward error correction]] (FEC) into the [[Amateur Satellite Service]], with FEC applied to the 400 bit/s PSK telemetry from the now-defunct [[AO-40]] satellite.

In June 2014, Phil Karn was interviewed for the History of the Internet Project (HOTI). Phil Karn describes his contribution to the effort to reboot the 1978 International Sun/Earth Explorer-3 ([[ISEE-3]]).
The #ISEE-3 is also known as the International Cometary Explorer.

== Crypto export lawsuit ==
In 1994, the US State Department Office of Defense Trade Control ruled that while it was legal to export [[Bruce Schneier]]'s "Applied Cryptography" book under the rules for munitions export, it was illegal to export the source code in the book on electronic media such as a [[floppy disk]].

Phil Karn challenged this ruling, both in the courts and in testimony before Congress, and the case dragged on for years, until [[Bill Clinton]] dropped almost all export controls on freely available crypto source code on January 14, 2000; The judge mooted the case, resulting in no decision and no precedent.
