Abstract

U prvom dijelu ovog rada opisan je referenti model umrežavanja otvorenih sustava. Zatim su opisana četiri komunikacijska protokola aplikacijske razine, a to su HTTP, MQTT, MQTT-SN i CoAP. Također opisane su i njihove sigurne varijante.
Kako bi se zaštitili podatci prilikom prijenosa mrežom, potrebna je njihova enkripcija. Podatci se enkriptiraju i šalju TLS ili DTLS protokolom koji prije prijenosa izvršava „rukovanje“ s poslužiteljem.
U zadnja dva poglavlja ovog rada, opisana je implementacija studijskog primjera pametne brave. Korištena su četiri protokola i njihove sigur varijante. Ti protokoli su uspoređeni i analizirani prema unaprijed zadanim kriterijima.

Abstract (english)

The first part of this paper describes the Open Systems Interconnection model. Then four application-level communication protocols are described, namely HTTP, MQTT, MQTT-SN, and CoAP. Their safe variants are also described.
Encryption is required in order to protect data during network transmission. The data is encrypted and sent by the TLS or DTLS protocols which the server „handles“ before transmission.
The last two chapters of this paper describe the implementation of a smart lock study example. Four protocols and their safe variants were used. These protocols were compared and analyzed according to predefined criteria.
