Conversations over telephone line are easily monitored and therefore acceptable level of security is not provided. In this paper, we propose the design of scrambler for secure communication and real time implementation of it. Especially, we con reduce the complexity of hardware and implement it easily by designing the scrambling system which doesn't require synchronization signal, and provide the scrambling filter with a sufficient level of security of adding new gain into the scrambling system.
