WebAlthough GSM was designed as a secure wireless system, it can still experience attacks. GSM uses authentication measures, such as challenge-response authentication, which prompts a user to provide a valid answer to a question, and a preshared key that is in the form of a password or passphrase. GSM was intended to be a secure wireless system. It has considered the user authentication using a pre-shared key and challenge–response, and over-the-air encryption. However, GSM is vulnerable to different types of attack, each of them aimed at a different part of the network. The development of UMTS introduced an optional Universal Subscriber Identity Module (USIM), that uses a longer authentication key to give greater security, as well as mutually authenticating the …
