Abstract
U radu je predstavljen CAN standard, nakon čega su opisani njegovi nedostatci u pogledu sigurnosti. Navedena su određena postojeća rješenja zaštite CAN komunikacije, te pregled prednosti i nedostataka navedenih rješenja. U okviru ovog rada implementirana su dva rješenja zaštite CAN komunikacije temeljena na Data Encryption Standard i Advanced Encryption Standard kriptografskim algoritmima. Predstavljeni su standardi odabranih kriptografskih algoritama, a njihova implementacija je izrađena u programskom jeziku C u Eclipse razvojnom okruženju. Za ostvarenje zaštićene CAN komunikacije korištene su ugradbene računalne platforme temeljene na mikroupravljačima STM32F407. Naposlijetku je provedena verifikacija i evaluacija implementiranih kriptografskih algoritama. U svrhu verifikacije su izvedena tri eksperimenta, prvo pomoću Eclipse razvojnog okruženja na osobnom računalu, a nakon toga pomoću USB-CAN adaptera na ugradbenoj računalnoj platformi temeljenoj na mikroupravljačima STM32F407. Evaluacija implementiranih kriptografskih algoritama je provedena s obzirom na vrijeme izvođenja programskog koda, te s obzirom na razinu prometa na CAN sabirnici. Izvedena su tri eksperimenta na ugradbenoj računalnoj platformi temeljenoj na mikroupravljačima STM32F407. Promatrani su slučajevi različitog sadržaja bloka kriptografskih algoritama, različite veličine pojedinog podatka koji se pakira u blok konstantne veličine, te različite ukupne količine kriptiranih podataka.
Abstract (english)
This master’s thesis presents the CAN standard, followed by a description of its security flaws. Certain existing solutions for protecting CAN communication are mentioned, along with an overview of the advantages and disadvantages of these solutions. Within this work, two solutions for securing CAN communication based on Data Encryption Standard and Advanced Encryption Standard cryptographic algorithms are implemented. The standards of the selected cryptographic algorithms are introduced, and their implementation is done in the C programming language in the Eclipse development environment. Embedded computer platforms based on STM32F407 microcontrollers are used for achieving secure CAN communication. Finally, the verification and evaluation of the implemented cryptographic algorithms are conducted. Three experiments were carried out for verification, first using the Eclipse development environment on a personal computer, and then using a USB-CAN adapter on an embedded computer platform based on STM32F407 microcontrollers. The evaluation of the implemented cryptographic algorithms is done concerning the execution time of the code and the level of traffic on the CAN bus. Three experiments were performed on the embedded computer platform based on STM32F407 microcontrollers, considering different content of cryptographic algorithm blocks, different sizes of individual data packed into blocks of constant size, and different total amounts of encrypted data.
