In the realm of classical cryptography, the GSM system, which stands for Global System for Mobile Communications, employs 11 Linear Feedback Shift Registers (LFSRs) interconnected to create a robust stream cipher. The primary objective of utilizing multiple LFSRs in conjunction is to enhance the security of the encryption mechanism by increasing the complexity and randomness
