Optimized PN Sequence Generation using Elliptic Curve Cryptography and UWD

Abstract

The Code Division Multiple Access (CDMA) technique is developed for military applications and also utilized in civilian application for the need of information hiding and secure signal transmission. The major issue occurs during the transmission in CDMA system is the security of data. In this proposed work, Universal Wind Driven (UWD) optimized ECC based PN sequence generation. Initially Pseudo Noise (PN) sequence is generated on the basis of Elliptic Curve Cryptography (ECC). The PN sequences have the characteristics of being like random noise with low correlation compared to any other sequence in the set. The original data is combined with optimal PN sequence and modulated by BPSK modulation and transmitted through the AWGN channel and demodulated by BPSK demodulation. The performance results proved that proposed work is efficient compared to other techniques.
