Säkerhetsanalys av ett smart lås (Swedish)
Abstract [en]

The Internet of Things (IoT) market has expanded and the variety as well as quantity of IoT devices has been rapidly increasing. Which also bring new security threats as new vulnerabilities are found within IoT devices. One area where these devices are being used is in smart homes and where smart locks especially needs to be designed in a secure way. This study aims to assess the security of a smart lock unit. We first present a background including threat modelling and previously found vulnerabilities. Then a methodology section for different attacks performed as well as the results from doing them. Finally, a discussion where we assess the security implications of the results. The conclusion from the results are that the smart lock exhibits vulnerabilities in its design. Specifically in its file system encryption, resistance to disruption attacks and the consistency of access granted to guests. 

Abstract [sv]

Marknaden för Internet of Things (IoT) har expanderats och varieteten såväl som kvantiteten av IoT enheter har snabbt ökat. Som också för mer sig nya säkerhetshot då nya sårbarheter hittas i IoT enheter. Ett område där dessa enheter används är i smart hem och där smarta lås speciellt behöver designas på ett säkert sätt. Den här studien har som syfte att bedöma säkerheten av ett smart lås. Först presenterar vi en bakgrund vilket inkulderar hotmodellering och tidigare hittade sårbarheter. Sedan en metod del för de olika attacker utförda såväl som resultat av att utföra dem. Slutligen, en diskussion där vi bedömer säkerhetsimplikationerna av resultaten hittade. Slutsatsen från resultaten är att det smarta låset visar på sårbarheter i dess design. Speciellt i sitt kryptering av filsystemet, motstånd till störnings attacker och varaktigheten av tillgång som beviljat till gäster.
