In this paper we present a joint encryption and coding scheme with both high levels of security and reliability of the transmission. These two aims are usually present in wireless data transmission systems. The scheme is based on efficient Non Binary Low Density Parity Check codes which were selected for this design because they outer perform their binary counterparts. Encryption operations over the parity check matrix of the code, increase security of the scheme, without producing any degradation in the corresponding Error Rate performance, as usually happens when encryption and error control coding are applied separately.
