Firstly, the key frames were extracted from the video sequence. Then, the features detected between adjacent key frames were guided and matched by motion displacement, which was calculated by the optical flow field. With the RANSAC robust estimation and cascade of homography matrix, the homography matrix of the adjacent key frame and the nonadjacent key frame was got. Finally, the seamless mosaic was rendered by image blending.

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。

The menu key function and enter key function interconvert through the menu key translation mode in the present invention, thereby achieving the effect of providing convenient key operation to the left-handed user.

在本发明中，通过菜单键转换模式对菜单键功能与确认键功能进行相互转换，达到了为左撇用户提供方便的键操作的效果。

In the symmetrical encryption system aspect, discussed the des algorithm with emphasis, has given it in the key management, the safe application aspect exists question; the problem which in the asymmetrical encryption system aspect, studies in with emphasis which rsa and the application has the question, the ecc merit and should pay attention and so on.through the quite symmetrical key encryption system and the public key encryption system good and bad points,summarize should use the mix key encryption system in the electronic commerce, both guarantee data security, and may enhance encrypts and deciphers the speed.

在对称加密体制方面，重点讨论了des 算法，给出了其在密钥管理、安全应用方面存在的问题；在非对称加密体制方面，重点研究rsa及其应用中存在的问题、ecc的优点及应注意的问题等。通过比较对称密钥加密体制和公开密钥加密体制的优缺点，总结出在电子商务中应采用混合密钥加密体制，既保证数据安全，又可提高加密和解密速度。

By introducing XOR operation and one-way function chains to group key management schemes based on the keys tree, a new group key management scheme based on the keys tree, XOR operation and one-way function chains is proposed. Initialization, member adding and member evicting operations are introduced. The new scheme is compared with three other group key management schemes which are based on the keys tree:SKDC, LKH, and OFT. As far as transmission, computation and storage costs are concerned, the performance of the new group key management scheme is the best.

摘 要：在基于密钥树的组密钥管理方案中引入了XOR操作以及单向函数链，提出了一种新的基于密钥树、XOR操作以及单向函数链的组密钥管理方案，介绍了新方案中初始化、成员加入以及成员退出的操作，将新方案与3种基于密钥树的组密钥管理方案SKDC，LKH，OFT进行了比较，数据表明：就传输、计算以及存储开销而言，新的组密钥管理方案性能最优。

Its birth is in key word is decision-making in to the search engine optimizes worker enlarge wide train of thought, basis before circumstance, major search engine optimizes service business to pay close attention to most is the core key word in the website, rank that those who emphasize also is core key word, and oversight the key word of a few little flow.
