Abstract :
A wiretap channel models a communication channel between a legitimate sender Alice and a legitimate receiver Bob in the presence of an eavesdropper Eve. Confidentiality between Alice and Bob is obtained using wiretap codes, which exploit the difference between the channels to Bob and to Eve. This paper discusses a first implementation of wiretap lattice codes using USRP (Universal Software Radio Peripheral), which focuses on the channel between Alice and Eve. Benefits of coset encoding for Eve´s confusion are observed, using different lattice codes in small dimensions, and varying the position of the eavesdropper.
