proxy attack

In the proxy share generation stage, due to the revocation of Shamir's threshold secret sharing scheme, each proxy signer in the proxy group owns the common proxy share, this can not only efficiently withstand the coalition attack, but also reduce the computational complexities.

取消了Shamir门限秘密分享方案在代理密钥生成阶段的应用，所有代理签名人持有共同的代理密钥，既有效地抵御了合谋攻击，又减小了计算复杂性。

Through the cryptanalysis of a new threshold proxy signature scheme based on bilinear pairings, it is found that the scheme cant resist forgery attack and public-key substitute attack.

给出了对一个已有的高效无证书签名方案的替换公钥攻击，表明了在该方案中，攻击者可以通过替换签名者公钥伪造签名；进而针对该攻击提出了改进方案。

The browser's same-origin policy does not prevent CSRF attacks because the attack requests are transmitted to the same origin in proxy for the intruding third-party site.
