Cílem práce je zpřístupnit dostupné prostředky pro přenos EDIFACTu v internetu, seznámit s bezpečnostními aspekty, které z daného vyplývají a přiblížit je oboru dopravy v ČR v návaznosti na automatizované informační systémy i jim předcházející prvotní vkládání dat z webových formulářů, především menšími institucemi. Práce nově představuje normy AS1, AS2 a AS3 skupiny EDIINT pro přenos EDI zpráv internetem pod protokoly SMTP, HTTP a FTP.
