Abstract :
In this paper, we present a novel space time coding scheme for the MISO wiretap channel. This method ensures that information theoretic secrecy is realised with modest computational complexity and a controllable trade off between power consumption and secret channel secrecy. One important aspect of this work is that it does not rely on unrealistic assumptions and only requires minimal protocol agreement between the transmitter and the intended receiver without any exchange of quantitative information. This scheme also has the benefit of having a predictable performance, hence allowing flexibility in the choice of key parameters. Finally, we show that unlike many MISO or MIMO secrecy schemes, it scales very well as the number of antennas is increased.
