  Frequently Asked Questions

  Why is mobile banking over GSM considered insecure?

  GSM networks are vulnerable to unauthorized access and eavesdropping because security was not a primary focus in their initial architectural design.

  What are the main flaws in GSM authentication algorithms?

  The project identifies significant problems with A3/A8 and A5 algorithms, which can lead to compromised data during mobile transactions.

  What is the proposed solution for secure SMS banking?

  The study develops a secure SMS protocol with a specific message structure and sequence to protect sensitive banking information.

  How does OFDM improve mobile data transmission?

  OFDM is a multicarrier modulation method that provides high-speed functions and reduces noise/interference in wireless communication.

  What were the simulation results in MATLAB?

  The simulations succeeded in achieving limited noise and interference, demonstrating a more reliable way to transmit data without losing information.
