20.500.12556/RUL-179226 Posodabljanje programske opreme ob omejenih virih Software updates under resource constraints Internet stvari (IoT) predstavlja eno najhitreje rastočih področij sodobne informatike, kjer naprave delujejo z izrazito omejenimi procesorskimi, po- mnilniškimi in energetskimi viri. Zaradi teh omejitev je varno posodabljanje programske opreme zahtevna naloga, saj mora zagotoviti zanesljiv prenos, preverjanje integritete in čim manjšo porabo energije. Obstoječe rešitve po- gosto ne omogočajo celovitega preverjanja, ali je bila posodobitev uspešno nameščena in ali naprava po njej deluje pravilno. Magistrsko delo obravnava razvoj razširjene implementacije standarda IETF SUIT, ki združuje energetsko učinkovitost, varnost in interoperabil- nost. Predlagana rešitev temelji na dvoslojni arhitekturi, ki vključuje strežni- ško komponento in komponento na napravi, ter uvaja mehanizme za odda- ljeno preverjanje namestitev. Z uporabo kompaktnega formata CBOR in kriptografskih mehanizmov COSE delo raziskuje ravnovesje med zanesljivo- stjo, varnostjo in porabo energije ter prispeva k razvoju univerzalnega in s standardom skladnega sistema za varne posodobitve IoT-naprav. The Internet of Things (IoT) represents one of the fastest-growing areas of modern computer science, where devices operate under strict constraints in processing power, memory, and energy availability. These limitations make secure firmware updates particularly challenging, as they must ensure reli- able data transfer, integrity verification, and minimal energy consumption. Existing solutions often fail to provide comprehensive confirmation that an update has been successfully installed and that the device continues to op- erate correctly afterwards. This master’s thesis presents the development of an extended implemen- tation of the IETF SUIT standard, combining energy efficiency, security, and interoperability. The proposed solution is based on a two-layer architecture consisting of a server component and a device-side component, and introduces mechanisms for remote installation verification. By employing the compact CBOR format and COSE cryptographic mechanisms, the thesis explores the balance between reliability, security, and energy consumption, contributing to the development of a universal and standards-compliant system for secure firmware updates on IoT devices.
