The historical parts of the Priestly Code depend on the Yahwistic and the Elohistic documents, but Wellhausen's adherents believe that the material of these documents has been manipulated so as to fit it for the special purpose of the Priestly Code; Dillmann and Drive maintain that facts have not been invented or falsified by P, but that the latter had at hand other historical documents besides J and E. As to the legal part of P, Wellhausen considers it as an a priori programme for the Jewish priesthood after the return from the captivity, projected backwards into the past, and attributed to Moses; but other critics believe that P has systematized the pre-exilic customs of worship, developing then, and adapting them to the new circumstances.

历史部分祭司码取决於Yahwistic和Elohistic文件，但豪森的信徒认为，这些文件材料已被操纵，以适应它的特殊用途的祭司码； Dillmann和驱动保持这一事实没有发明或伪造的P ，但后者在手其他历史文件除了J和大肠杆菌作为法律的一部分磷，豪森认为这是一个先验方案犹太祭司返回后从被关押，预计倒退到过去，由於摩西；但其他批评者认为磷已系统化前放逐海关的礼拜，然后发展，并使之适应新的情况。

Our scheme is unforgeable, exculpable, unlinkable, and coalition-resistant.

在我们的系统中，签章不能被伪造、群体成员不会被构陷签章、签章之间没有关联、而且能避免联合攻击。

We also prove that the new scheme is not only indistinguishable against chosen-ciphertext attacks but also existentially unforgeable against chosen-message attacks.

可证明新方案在选择密文攻击下不可区分，在选择消息攻击下存在不可伪造。

Secondly, we show a security flaw in a previous certificateless ring signcryption scheme (Wang et al.'s scheme). It is not existentially unforgeable for Type I adversary.

其次，本论文指出了Wang等的无证书环签密方案的一个安全缺陷，对于第一类攻击者，此方案并不是存在不可伪造的。

We formalized a notion of security for partial delegation with warrant proxy signature schemes, i.e., existentially unforgeability under an adaptive chosen-message attack and an adaptive chosen-warrant attack. We compare the new model with the previous formal models and identify their weakness.

重新给出了具有证书的部分代理签名的安全定义，即适应性选择消息攻击和适应性选择授权文件攻击下的不可存在性伪造，建立了形式化安全模型。
