Poiché utilizzo una vecchia scheda SIM (10-15 anni), mi chiedevo se l'hardware e il software della sim card equivalessero alle nuove sim card.
Le vecchie carte sim (10-15 anni) sono le stesse di quelle nuove?
Le carte usim sono già in uso?
Come esempio della crittografia, come sapere se la mia scheda supporta A5 / 1 o A5 / 3?
• A stream cipher known as the A5 algorithm.
– A5/0: no encryption.
– A5/1: original A5 algorithm used in Europe.
– A5/2: weaker encryption algorithm created for export, in
removal.– A5/3: strong encryption algorithm created as part of the 3rd Generation Partnership Project (3GPP)
Alcune persone (scriptkiddies-criminali ...) sono in grado di queste minacce?
Threats to SIM Data
• GSM SIMs can be cloned because authentication protocol has flaw
–COMP128 is popular algorithm and a published standard
• Leaks information at every connect attempt.
• Chosen-plaintext attack
–Approximately 150,000 queries required takes about 8-11 hours with a suitable smart card reader
