Nowadays remote network access is becoming an increasingly common need among the business companies and engineers. A VPN (virtual private network) connection is used in order to access nodes on a remote network, but if no VPN connection to a remote network is available, a different approach should be considered. The objective of this paper is to describe a solution for connecting to the GUI (graphical user interface) of Embedded Devices on a remote private network, where a VPN connection is not available, and where Internet connection is not stable, usually a LAN (local area network) on vehicles. A solution to this problem dives deeply into the existing Internet communication protocols, Internet structure, and Internet security. It implements a client program for unique embedded device architectures, a server program existing in the cloud, and establishes communication between the two with the help of its unique protocol on top of the existing Internet protocols. The result is secure direct access to the GUI interface of a remote embedded device.

Abstract

Dan danes postaja oddaljeni dostop do lokalnega omrežja vse pogostejša potreba med podjetji in inženirji. Virtualno povezava VPN (navidezno zasebno omrežje ang. virtual private network) se uporablja za dostop do vozlišč na oddaljenem omrežju, ampak če nam taka VPN povezava ni na voljo, je potrebno razmisliti o drugačnem pristopu. Cilj te diplomske naloge je opisati rešitev za povezavo z GUI (grafični uporabniški vmesnik ang. graphical user interface) vgrajenih naprav v oddaljenem zasebnem omrežju, kjer nam virtualna povezava VPN ni na voljo in kjer internetna povezava ni stabilna, običajno LAN (lokalno omrežje ang. local area network) na vozilih. Rešitev tega problema obravnava obstoječe internetne komunikacijske protokole, internetne strukture in internetno varnost. Zajema odjemalni program za edinstvene arhitekture vgrajenih naprav, strežniški program obstoječ na oblaku, in komunikacijo med obema s pomočjo edinstvenega protokola, ki sloni na obstoječih internetnih protokolih. Rezultat je varen neposreden dostop do grafičnega vmesnika vgrajenih naprav.
