== Career ==
As a graduate student at the [[University of California, Los Angeles|University of California Los Angeles]] (UCLA) in the 1960s, he was part of the team that developed the protocols for the [[ARPANET]] which were the foundation for today's [[Internet]].<ref>[http://internethalloffame.org/inductees/steve-crocker "Official Biography: Steve Crocker"], Internet Hall of Fame, Internet Society, retrieved September 14, 2013.</ref>  He said "While much of the development proceeded according to a grand plan, the design of the protocols and the creation of the RFCs was largely accidental."{{Refn|RFCs began as informal technical notes, "requests for comments", of the Networking Working Group (NWG).|group=nb}} He was instrumental in forming a Network Working Group (NWG) in 1969 and was the instigator of the [[Request for Comments|Request for Comment]] (RFC) series,<ref>"I Remember IANA", V.

Retrieved September 14, 2013.</ref> Crocker led other graduate students, including [[Jon Postel]] and [[Vint Cerf]], in designing a host-host protocol known as the [[Network Control Program (ARPANET)|Network Control Program]] (NCP).{{Refn|Crocker said "NCP" later came to be used as the name for the protocol, but it originally meant the program within the operating system that managed connections. The protocol itself was known blandly only as the host-host protocol.'|group=nb}} They planned to use separate protocols, [[Telnet]] and the [[File Transfer Protocol]] (FTP), to run functions across the ARPANET.{{Refn|The [[NPL network]] team also envisaged the need for levels of data transmission in 1968. Both were early examples of the protocol layering concept incorporated in the OSI model.|group=nb}}<ref name=":26">{{cite journal |last=Hauben |first=Ronda |year=2004 |title=The Internet: On its International Origins and Collaborative Vision |url=http://www.ais.org/~jrh/acn/ACn12-2.a03.txt |journal=Amateur Computerist |volume=12 |issue=2 |access-date=May 29, 2009}}</ref><ref name=":17">{{Cite IETF|rfc=1000|title=The Request For Comments Reference Guide|date=1987|last1=Reynolds|first1=J.|last2=Postel|first2=J.}}</ref> NCP codified the ARPANET network interface, making it easier to establish, and enabling more sites to join the network.<ref>{{Cite web |title=NCP, Network Control Program |url=https://www.livinginternet.com/i/ii_ncp.htm |access-date=2022-12-26 |website=LivingInternet |language=en-US}}</ref><ref>{{Cite book |url=https://books.google.com/books?id=dRRDDwAAQBAJ&q=NCP |title=UGC -NET/JRF/SET PTP & Guide Teaching and Research Aptitude |publisher=High Definition Books |page=319 |language=en}}</ref>

While at UCLA Crocker taught an extension course on computer programming (for the [[IBM 7094]] [[mainframe computer]]).  The class was intended to teach digital processing and assembly language programming to high school teachers, so that they could offer such courses in their high schools.  A number of high school students were also admitted to the course, to ensure that they would be able to understand this new discipline.  Crocker was also active in the newly formed UCLA Computer Club.

Crocker has been a program manager at [[Defense Advanced Research Projects Agency]] (DARPA), a senior researcher at [[University of Southern California|USC]]'s [[Information Sciences Institute]], founder and director of the Computer Science Laboratory at [[The Aerospace Corporation]] and a vice president at [[Trusted Information Systems]]. In 1994, Crocker was one of the founders and chief technology officer of [[CyberCash]], Inc.<ref>{{Cite web|last=Parallelus|title=Steve Crocker, Ph.D.|url=https://krasnow.gmu.edu/trustees/steve-crocker-ph-d/|access-date=March 13, 2021|language=en-US}}</ref><ref>{{Cite web|title=hjp: doc: RFC 1898: CyberCash Credit Card Protocol Version 0.8|url=https://www.hjp.at/doc/rfc/rfc1898.html|access-date=March 13, 2021|website=www.hjp.at}}</ref> In 1998, he founded and ran Executive DSL, a [[Digital subscriber line|DSL-based]] ISP.
