Secret Key Agreement Techniques based on Multipath Propagation Characteristics

Chapter

Abstract

As information society progresses, wireless communications such as cellphone and WLAN (Wireless Local Area Network) systems will become more widely and rapidly accepted as the means to communicate. Unfortunately, there are many perceived weaknesses inherent in the security of wireless communications– largely due to the fact that the signals are transmitted through the air and are easily captured by third parties. Examples of such threats are found in eavesdropping of transmitted data on a radio channel, illegal and/or unauthorized access to public WiFi networks, and so on. In fact, security for wireless systems has been recognized as a major technical challenge that needs to be addressed in order for wireless systems to be the basis for many future applications.
