A Linear Feedback Shift Register (LFSR) is a key component in the generation of pseudorandom sequences, which are crucial in stream ciphers for cryptographic applications. The LFSR generates a key stream by shifting bits through a register and using a feedback mechanism defined by a polynomial. This process is deterministic and relies heavily on the
