详细来说
1、墙对Hy2等新协议似乎没有强力的检测手段，这点从最近的白嫖节点和白嫖机场开始广泛采用Hy2直连并表现出惊人的稳定性可知。
2、往年春节（除夕）期间的大范围污染并没有出现
3、DDoS有愈演愈烈的趋势，从过往的经验来看，DDoS的强度与墙的强度会保持制衡。
准确来说不是墙低了，应该是墙有段时间没有升级了，这很奇怪。以目前的趋势来看，在现在的情况下Hy2很可能会在市场需求下快速普及开来。
当然这只是我的观察，各位机场主如果近期被墙的也属于正常情况，毕竟只要墙一直在，被墙就只是时间问题。

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
