Wireless communication is one of important means for connecting everyone from
anywhere in the world at any time. Though the prevalence of wireless technologies
brings many advantages, the nonnegligible fact is that the users are more exposed
to the attacks of adversaries due to the broadcast nature of wireless signals. In
view of that, the communication security has been drawn more and more attention.
The traditional manner to reinforce the security of communication is to use the
encryption techniques to protect user data in the upper layers of the communication
stack. Even though current efforts provide solutions from certain perspectives, these
methods are neither adaptive nor flexible enough to provide security mechanism due
to the computational tasks and system complexity. Furthermore, the characteristics
of wireless channels, such as difference, reciprocity and so forth, make it possible to
transmit signals safely between transmitter and receiver in the physical layer. Such
an idea has been verified to effectively improve the security of communication.With
the development of wireless communication techniques, physical layer security has
become one of hot topics. In this section, we will give some brief introduction
about physical layer security from concept, technical evolution, to its applications
in wireless networks.
