We consider secure wireless communications via physical-layer security mechanisms, particularly coding for secrecy mechanisms, combined with self-interference generation. We present results of a prototype implementation of a scrambled coding for secrecy mechanism with self-interference generation by the legitimate receiver. The prototype implementation is performed in real-world software-defined radio devices through a GNU Radio implementation. Our preliminary results shows a better error vector magnitude value on the legitimate receiver due the self-interference cancellation while Eve gets a more disperse constellation point values, leading to a worst decoding results.
