Linear Feedback Shift Registers (LFSRs) are critical components in the design of stream ciphers used in classical cryptography. Their simplicity and efficiency make them attractive for generating pseudo-random sequences. However, despite these advantages, LFSRs are susceptible to various forms of cryptanalysis, including correlation attacks and algebraic attacks. These attacks exploit inherent vulnerabilities in LFSRs, compromising
