一种基于分布式ad hoc无线传感器网络的辅助认证机制

介绍了无线网络中一个基于对称加密算法的物理层辅助消息认证机制,在此基础上提出了一个基于广播信道的新型消息认证机制.提出的机制通过利用物理层信道响应的时间和空间的独立性将传统的消息认证机制和物理层认证机制相结合,达到快速认证的目标而且传输负载最小.并与公钥基础的物理层辅助认证机制和传统的上层认证机制进行了比较,也进行了扩展分析和仿真测试,验证了所提出认证机制的性能.

An authentication for distributed ad hoc wireless sensor networks

This paper introduces a symmetric cryptography-based physical layer assisted message authentication scheme in wireless networks, and proposes a novel message authentication framework over broadcast channels, where the proposed framework integrate the conventional message authentication schemes and the physical layer authentication mechanisms by taking advantage of temporal and spatial uniqueness in physical layer channel responses, aiming to achieving fast authentication while minimizing the packet transmission overhead. Our scheme is verified by comparing with public key infrastructure-based physical layer assisted authentication scheme and traditional upper layer authentication schemes through extensive analysis and simulation.
