Then, a self-certified anonymous proxy signature scheme based on the view of self-certified public key policy and the scheme of anonymous proxy signature are proposed. The proposed scheme not only lightens the burden of verifier, but also has characteristics such as anonymousness and trackability.

然后，结合自证明公钥体制和匿名代理签名，设计出一种自证明匿名代理签名方案，此方案不仅能减轻验证者的负担，还具有匿名性和可跟踪性的特点。

Although the Preissman scheme of KP equation is multisymplectic, it took too efforts to realize, Hence we elimate the auxiliary variable by a trivial computation and obtained the multisymplectic forty-five points scheme of KP equation. And then, we test this forty-five points scheme on soliton and solitary waves over long time intervals, the numerical results shows the propagation and interact of soliton and solitary waves.

但是在实际的数值实验中，由于需要计算共轭动量的值，Preissman格式需要占用的计算内存比较大，计算时间比较长，因此我们在数值格式中消去共轭动量，最后得到与多辛Preissman格式等价的一个多辛45点格式，我们用这个格式进行了数值实验，数值实验结果很好地显示了孤立子和孤立波的传播与碰撞。

A second order accurate, high resolution scheme, called WSUC scheme, has been proposed. This scheme is total variation bounded and unconditionally stable in the sense of convective numeral stability.

First of all, this thesis points out that Qian-Cao-Xue\'s scheme (the first threshold proxy signature scheme from bilinear pairings) does not possess the property of strong unforgeability, presents two attacks and proposes an improved scheme which can resolve the security problem existing in their scheme.

本文主要研究了面向群体的数字签名中的代理数字签名、群数字签名及其应用，对一些数字签名的安全性进行了分析，设计了一些具有附加功能的数字签名。

S scheme which is a combination of Mambo et al.\'s proxy signature scheme and Zheng\'s signcryption scheme. Our analysis demonstrates that their scheme cannot guarantee strong unforgeability, strong identifiability, non-repudiation, and prevention of misuse.

他们的体制本质上是Mambo等人的代理签名体制和Zheng的签密体制的结合，安全性分析表明他们的体制不能满足强不可伪造性、强可识别性、不可抵赖性，也不能防止滥用。

This includes board band base pay structure scheme, piece work incentive scheme, monthly bonus scheme and year end bonus scheme.

其中包括宽带结构的基本工资方案，计件奖金方案，月度奖金方案、年终奖金方案。

The main results obtained are as follows:(1) A new multisignature scheme for specified group of verifiers is proposed;(2) A new signature scheme with threshold shred verification is proposed. Based on the proposed scheme, a new password shared authentication scheme is presented to repair the security flaw in Qi et al.

作者取得的主要研究成果如下：（1）提出一个新的针对指定接收组的多重签名方案；（2）提出一个新的门限共享验证签名方案，并设计了一个新的口令共享认证方案，该方案可以弥补祁明等的方案的不足；（3）指出Lim et al。

In comparison with the observations derived from NOAA AVHRR, under the framework of NCAR CLM3, SCF schemes like CLM3 default, Douville1995, and Roesch 2001 underestimate SCF over vast areas, snow lines simulated in these three schemes are located to the south of that in the AVHRR observation, especially in autumn when snow pack begins to establish; Wu2004 scheme also underestimates SCF in the Eurasian continent in autumn; Yang1997 scheme slightly overestimates SCF, especially along the southern border of the snow covered area; Niu2007 scheme which accounts for the seasonal variation of snow density overcomes the positive bias of SCF simulated by Yang1997 scheme to some extent.

结果表明，在NCAR CLM3的物理过程框架之下，CLM3、Douville1995、Roesch2001三种方案低估了广大地区的积雪覆盖率，模拟的雪线位置偏北，尤其是在秋季积雪初期；Wu2004方案低估了秋季欧亚大陆的积雪覆盖率；Yang1997方案模拟的积雪覆盖率有些偏高，尤其是在积雪覆盖区的南部边缘；考虑积雪密度变化的Niu2007方案一定程度上克服了Yang1997方案的正偏差。
