Security is crucial to a wide range of wireless data applications and services. This paper presents a simulation based study of a wireless communication system with the implementation of secured asymmetric RSA cryptographic encryption/decryption algorithm on text message transmission. The system under investigation incorporates 2/3-rated CRC channel coding and QPSK digital modulation over an Additive White Gaussian Noise (AWGN) channel. For tackling the security problems a text message is first RSA encrypted at the transmitter while it is decrypted at the receiver end and compared for different levels of SNR. The computer simulation has been performed using Matlab 2009b programming language
