摘要:

物理层安全技术的研究正逐渐成为信息安全和无线通信两个领域的交叉热点。回顾了物理层安全技术的背景和研究现状,并对其未来的发展进行了展望。物理层资源的多样性和惟一性等特征以及十几年来物理层传输技术的涌现和发展,为物理层安全技术的研究开展提供了广阔的空间。目前物理层安全技术的研究以引入各种新技术之后的窃听信道容量分析为基础,并且已经出现了物理层鉴权技术、物理层密钥产生技术和物理层加密技术等新兴的研究方向。

Abstract:

Physical layer security is becoming an emerging research area of information security and wireless communications. In this paper,the background and state-of-the-art of physical layer security are reviewed and the future of research is pointed out. The variance and exclusion of wireless resource,as well as the development of physical layer transmission techniques,bring up plenty of opportunities for physical layer security. Based on the secrecy capacity research of the wire-tap channel,physical layer authentication/key generation/identification methods are the current popular research topics.

Key words: wireless communication, physical layer security, wire-tap channel
