该类水印的主要缺点是：嵌入率较低以及对同步（例如变时间和变调处理）等某些攻击的鲁棒性较差。

The main shortcomings of this watermarking are the low embedding rate and the lack of robustness to synchronization attacks (such as time-scale modification and pitch-scale modification).

随着时间同步服务的盛行，它越来越成为恶意攻击的目标。

As time synchronization-based services become more prevalent, the synchronization infrastructure will become the target of malicious attacks.

实验结果表明，该协议能避免单纯采用时间戳所带来的时钟同步问题，具有较好的抗重放攻击能力。

Experimental results show that, this protocol can effectively avoid the problem of clock synchronization when only use timestamp, and good anti-replay attack capacity.
