In electronic payment system, it is more suitable to introduce the distributed electronic bank scheme in networks environment. However, in current scheme, the users obtain their cards issued by the bank in which they have opened their accounts and withdraw and store their e-coin at the bank. Due to limits of current network neckbottle and security, dispersed and mobile users in different areas, there are some defects in a practical monadic account e-bank scheme.

摘要在电子支付系统中，采用分布式电子银行方案更适合于网络运行环境，然而在现行的分布式电子银行方案中，每个用户局限在所开帐户的电子银行取得签发的Smart Card和提取或存储电子货币，由于网络的瓶颈作用和安全缺陷，以及用户所处地域的分散性和流动性等因素的限制、使得单一开户的银行方案在实际应用中其分布式特性并未充分得以发挥。

After adopting the theory of large scale turbulent simulation to natural rivers, upwind scheme plus Peaceman Rachfords alternating scheme and Douglas alternating scheme are used in this model.

Simulations show that the proposed scheme has a better performance than that of the traditional scheme when the channel information is not perfectively known at transmitter. And the scheme is obviously robust when the uncertanty of channel information changing.

仿真结果表明：当发射端获得的信道信息不准确时，提出的算法表现出比传统特征波束成形算法更低的误比特率，并且当信道信息的不确定程度变化时，提出算法的性能有很好的鲁棒性。

The analysis results show that this scheme doesn't need additional memory space and increases the probability that neighbor nodes have the same key space. Compared with the pairwise key predistribution scheme, this scheme can increase the threshold of captured nodes and improve the security of WSN, and fits the network environment and meets the security requirements of WSN.

分析表明，该方案在不增加存储空间的情况下，提高了邻居节点拥有相同密钥空间的概率，并且与多密钥空间密钥对预分布方案相比，可大幅提高被俘节点的阈值，增强了网络安全性，能够较好地适应无线传感器网络的网络环境和安全要求。

To further enhance the security and connectivity for wireless sensor networks,proposed an improved key management scheme.introduced the scheme,a random key predistribution using multiple key spaces and multipath key reinforcement was based on group-based deployment model which in the paper of du wen-liang.analysis and simulations show that the scheme has lower memory and communication overheads, better ability against attacks besides good security performance.

为了进一步提高无线传感器网络的安全连通性，在分析du wen-liang等人的group-based节点投放模型的基础上，提出了一种改进的密钥管理方案：多密钥空间与多路径增强相结合的随机密钥预分配方案。结果分析表明，该方案需要较少的内存存储空间，不仅提高了系统的连通性，还降低了节点的被捕获概率。

On the basis of published paper, an ID-based provable secure and strong designated verifier signature scheme, a modified strong designated verifier signencryption scheme, and a modified extended aggregate signature scheme based on the supersingular elliptic curve is presented in this thesis.

在已有文献的基础上，综合形成了一种基于身份标识的超奇异椭圆曲线上的强指定验证者的数字签名方案、签密方案和可扩展的群签名方案。

In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.
