Abstract

Sigurnosni protokoli za zaštitu bežične komunikacije temelj su sigurnog načina prijenosa informacija i osiguravaju da osjetljivi podaci ne dođu u ruke zlonamjernih aktera koji bi ih mogli zlorabiti i potencijalno nanijeti štetu organizacijama, koristiti ih za stjecanje financijske dobiti, koristiti ih kako bi došli do drugih osjetljivih informacija ili njima pristupati resursima sa ograničenim pristupom. U ovome su radu opisani sigurnosni mehanizmi za zaštitu privatnosti komunikacije na sloju podatkovne poveznice OSI modela. Analiziran je protokol WPA2 i opisana je ranjivost ponovnim dogovaranjem ključa. Ostvaren je i opisan program za ispitivanje postojanja te ranjivosti.

Abstract (english)

Security protocols for the protection of wireless communication are the foundation for a secure way of transmitting information and ensuring that sensitive data does not come into the hands of malicious actors that could abuse them and potentiallly cause damage to organziations, use them for financial gain, use them to collect other sensitive data or use them to gain access to resources with limited access. This paper describes security machanisms employed for the protection of privacy of communication under OSI model's data link layer. WPA2 protocol is analyzed as well as the description of WPA2 key reinstallation attack. Program for testing the existence of said vulnerability is implemented and described.
