The objective of this chapter is to study practical coding techniques to provide security to wireless systems. First, the chapter will briefly introduce theoretical results relevant to low density parity check (LDPC) codes, polar codes and lattice coding for the wiretap channel. Then, it will propose practical secrecy-coding schemes able to provide a reliable and confidential wireless communication link betweenAlice and Bob. Finally, these practical wiretap codes are implemented in WiFi and long-term evolution (LTE) testbeds, and their confidentiality performance is evaluated using the bit-error rate (BER) as it is a simple and practical the metric for secrecy. The reader is referred to [1] for a throughout survey on recent advances related to the design of wiretap codes for information-theoretic metrics such as strong secrecy and semantic secrecy.
