Second workshop on trusted communications with Physical Layer Security (TCPLS2014)

Due to the broadcast nature of the wireless channels, security and privacy is of utmost concern for future wireless technologies. However, securely transferring confidential information over a wireless network in the presence of eavesdroppers that may intercept the information exchange between legitimate terminals, still remains a challenging task. Although security was originally viewed as a high-layer problem to be solved using cryptographic methods, physical layer security is now emerging as a new promising mean of defense to realize and enhance wireless secrecy in communications. In wireless physical layer security, the breakthrough idea is to exploit the intrinsic characteristics of the wireless channels, such as multipath fading, path losses, or noise, to transmit a message from a source to the intended receiver while keeping confidentiality from both passive and active eavesdroppers. After the success of the last year, the second workshop on trusted communications with Physical layer security aims to bring together practitioners and researchers from both academia and industry for discussion and technical presentations on fundamental and practically relevant questions related to the many challenges arising from secure communications at the physical layer.
