Abstract [sv]

Idag finns det flera olika typer av inpasserings system som använder någon form av ”smart card” eller mobil enhet som nyckel. De smarta låsen, som det oftast kallas, som använder sig av en mobile enhet, använder antingen Wi-­‐‑Fi eller Bluetooth för att kommunicera med inpasserings systemet. I den här uppsatsen kommer en relativt ny teknologi som kalls Near Field Communication (NFC) att utforskas. Användandet av NFC är på uppgång och det finns inkluderat i nästan varje ny mobil enhet som släpps på marknaden idag. Ett inpasserings system med hög säkerhet utvecklades genom att använda en mobile enhet med NFC kapabilitet tillsammans med en Raspberry Pi Linux plattform. Flera olika typer av autentiserings protokoll, mobila operativsystem och NFC användnings moder, analyserades och utvärderades för att säkerställa att systemet var så säkert som möjligt. Tillslut valdes ett autentiserings protokoll vid namn, Secure Remote Password (SRP), som integrerades ovanpå ett kort emulerings NFC ramverk som finns tillgängligt i Android operativsystemet. Det slutgiltiga systemet har hög säkerhet och är snabbt och responsivt och kan användas i flera olika situationer. NFC tillåter en mobile enhet att agera nyckel i ett inpasseringssystem och användandet kommer bara öka med den expanderande användare basen.
