Abstract

This paper presents data security enhancement using the multilayer linear feedback shift register (LFSR) cryptographic technique to overcome the problem of data hacking. The information security is achieved with a One Time Pad (OTP) algorithm developed in multilayer which defines the signal transmission in the medium. The Pseudorandom Noise (PN) sequence created by the primitive polynomial is used to get the seed values that are used to characterize OTP functionality. The single-layered LFSR cryptography is analyzed with a cascaded LFSR cryptography technique to prove the security of digitized data. The authentication key generation circuits for various levels of bit handling in data communication systems are implemented in LFSR cascaded cryptography in both encryption and decryption process. The cascaded multilayer cryptography is analyzed for improved data security and the results based on operating frequency, power consumption, delay, and memory usage prove that it suits well for developing modern network-based applications.
