Abstract

Sigurnost bežičnih senzorskih mreža često je zanemarena zbog ograničenosti procesorskih, memorijskih i energetskih resursa mrežnih čvorova. Iako je trošak uvođenja sigurnosnih primitiva u komunikaciju velik, nužno je u komunikaciji čvorova postići određenu razinu sigurnosti. Ovaj rad promatra bežične senzorske mreže u kontekstu interneta stvari i nastoji adresirati probleme koji se javljaju prilikom integracije čvorova s internetskim standardima. Da bi mogli govoriti o potpunoj i samostalnoj integraciji senzorskih čvorova s internetom, oni moraju implementirati protokole TCP/IP stoga nad kojima je bitno ostvariti određenu razinu zaštite komunikacije bez obzira na navedena ograničenja. Predloženo sigurnosno rješenje nastoji ispitati izvedivost i utjecaj uvođenja opće prihvaćenih i standardiziranih sigurnosnih mehanizama sveprisutnog protokola SSL/TLS u svijet bežičnih senzorskih mreža.

Abstract (english)

Problem of security in wireless sensor networks is often neglected due to the limitation of processor, memory and power resources of network nodes. Although the cost of introducing security primitives in communication is large, it is necessary to achieve a certain level of security due to potentially sensitive data. This paper looks at wireless sensor networks in the context of the Internet of Things (IoT) and seeks to address problems that arise in the process of integrating nodes with Internet standards. In order to achieve complete and autonomus integration with the Internet, sensor nodes must implement TCP / IP protocols and provide security mechanisms to reach a certain level of communication protection regardless of the aforementioned limitations. Security solution proposed in this paper seeks to examine the feasibility and impact of widely accepted and standardized SSL / TLS security mechanisms to the world of wireless sensor networks.
