物理层认证的信道编码方法

A Channel Coding Approach for Physical-Layer Authentication

Xiaofu Wu, Zhen Yang

摘要:

对于物理层身份验证,身份验证标记通常与消息同时发送,而无需太多带宽扩展。在本文中,我们提出了一个信道编码的方法,用于物理层认证。认证标签的生成可以被公式化为用于代码集合的编码过程,其中Alice和Bob之间的共享密钥被认为是输入,并且消息用于指定来自代码集合的代码。然后,我们证明了物理层认证方案的安全性可以通过解码来分析,并且物理层认证方案可以潜在地实现信息理论和计算安全。

英文摘要:

For physical-layer authentication, the authentication tags are often sent concurrently with messages without much bandwidth expansion. In this paper, we present a channel coding approach for physical-layer authentication. The generation of authentication tags can be formulated as an encoding process for an ensemble of codes, where the shared key between Alice and Bob is considered as the input and the message is used to specify a code from the ensemble of codes. Then, we show that the security of physical-layer authentication schemes can be analyzed through decoding and physical-layer authentication schemes can potentially achieve both information-theoretic and computational securities.
