摘要
无线Mesh网络是一种特殊的Adhoc网络,由于其共享无线传输媒介、动态拓扑的特点,容易遭受各种安全威胁。本文设计了一种适用于无线Mesh网络的一次性口令认证协议。该协议基于时间同步机制,采用HOTP-T算法,易于在令牌或IC卡等硬件上实现。分析表明:该协议能够有效抵御蛮力攻击、重放攻击,重同步机制容易实现,并且能够实现简单的双向认证,具有很高的安全性。
Wireless Mesh Network is a special kind of Ad hoc network. It is particularly vulnerable due to its features of shared wireless transmission medium and dynamic changing topology. An OTP authentication protocol suitable for wireless mesh networks is proposed based on time synchronization and HOTP–T algorithm. It can be easily implemented on token or IC card. The analysis demonstrates that such a protocol is highly secure to resist brute-force attack and replay attack effectively, realize resynchronization and simple dual authentication easily.
