Abstract

Persontilknytning av et aktivt såkalt SIM-kort (11) for et mobilradio- telefonsystem av typen GSM er utført på et sted (3) som er tilkoblet en sentral datamaskin (l) i systemet og via et datasambandsnett (2). Størrelser som angir kortets identitet (IMSI) og en autentiseringskode (Ki) overføres i linjekodet form (DES) til et EDB-termi- nalutstyr (9) på stedet, idet kortet (11) er ført inn i en leser (10). Etter linjedekoding i/ved hjelp av de- kodeenheter (12, 13) overføres resul- tatet til kortet på en måte som hindrer uautorisert tilgang til data. Dette kan utføres i en sikkerhetsboks eller ved dobbel koding (A3/A8) for kodene IMSI og Ki, idet dekodingen utføres inne i kor- tet ved hjelp av en unik kortkode Ksim.Personal connection of an active so-called SIM card (11) to a GSM mobile radio telephone system is carried out at a location (3) connected to a central computer (1) in the system and via a data connection network (2). Sizes indicating the identity of the card (IMSI) and an authentication code (Ki) are transmitted in line coded form (DES) to an on-site computer terminal equipment (9), the card (11) being inserted into a reader (10). After line decoding in / by means of decode units (12, 13), the result is transferred to the card in a way that prevents unauthorized access to data. This can be done in a security box or by double coding (A3 / A8) for the codes IMSI and Ki, the decoding being performed inside the card by means of a unique short code Ksim.
