知道了这一点，假设攻击者构造了一条IC MP回应消息，它的头中包含伪造的任意主机a的源地址，如192.168.2.2。
Knowing this, imagine that an attacker constructs an ICMP echo message containing the spoofed source address of some arbitrary Host a, such as 192.168.2.2, in its header.
这种攻击和Rails验证储存在cookie中的消息摘要有关，这个缺陷允许一个攻击者来决定伪造签名能够在什么时候通过验证。
Such an attack is related to how Rails verifies message digests in the cookie store and might allow an attacker to determine when a forged signature is partially correct.
这样就可以开始向空SOAP消息体里填充伪造的消息内容了，由于签名验证无误，那攻击者定义的任何一个操作都可以被有效地执行了。
The filling of the empty SOAP body with bogus content can now begin, as any of the operations denied by the attacker can be effectively executed due to the successful signature verification.

Unauthorized access using techniques such as dictionary attack and falsified message.
该方案能受到替换公钥攻击，以至于任何人都能对任何消息成功伪造签名。
The certificateless signature scheme can suffer from public key replacement attack so that any one can forge a valid signature on any message.
在随机预言模型下，可证明该方案在适应性选择消息攻击下是存在不可伪造的。
It is proven to be existential unforgeable against chosen message attack under the random oracle model.
方案保证了签名效率和签名的强壮性，在随即预言模型下，证明了其在适应性选择消息攻击和身份攻击下都能抵抗存在伪造。
The proposed signature scheme ensures the efficiency and robustness of signature, and can defend existential forgery on adaptively chosen message and ID…

This paper will show that Zhang et al. 's scheme is insecure, any group member colludes with repeal center can generate a valid group signature without using his secret parameters.
