摘要

未来信息网络对于时间同步的精度和可靠性提出了更高的要求，为了验证时间同步协议潜在的安全隐患，文章对精确时间协议（PTP）的报文和延时攻击进行了实验模拟分析。为解决传统加密方式无法抵御时间同步协议延时类攻击的问题，文章将PTP与量子秘钥分发技术相结合，提出了一种面向未来网络同步可靠性需求的量子增强安全同步协议，在加密防控报文攻击的基础上，实现对延时类攻击的检测和预警，触发保护机制。理论分析表明，该协议可主动预防针对时间同步协议的安全攻击，实现时间同步信息的安全传输。

Abstract

Future information networks will place higher requirements on the accuracy and reliability of time synchronization. In order to study the potential security risks of the time synchronization protocol

an experimental simulation analysis of the packet attack and delay attack of the Precise Time Protocol (PTP) is carried out. In order to solve the problem that the traditional encryption method cannot resist the delay attack of the time synchronization protocol

a quantum-enhanced secure synchronization protocol is proposed

which combines PTP with quantum key distribution technology to satisfy future network synchronization reliability requirements. On the basis of defending against message attacks by encryption

it implements detection and early warning of delay-type attacks and triggers a protection mechanism. The quantum-enhanced secure synchronization protocol can actively prevent security attacks against time synchronization protocols

and realizes secure transmission of time synchronization information.
