Speech encryption using the nonlinear filter generator
Aïssa Belmeguenaï, Khaled Mansouri, Ammar Medoued · 2015
In this communication, we propose a stream cipher system based on nonlinear filter generator for speech data encryption. The cipher is simple and highly efficient. It is implemented to encrypt and decrypt speeches data. Several experimental tests are done for proving the system performance. The results show that the proposed scheme is secure certain attacks.
