查询词典 key base

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.

它的诞生在关键字决策中给搜索引擎优化工作者扩宽了思路，根据以往的情况，大部分搜索引擎优化服务商关注最多的是网站中的核心关键字、强调的也是核心关键字的排名，而忽略了一些小流量的关键字。

The third key-press is regarded as letter affirmance key-press on mini key-board, at the same time, identifies sound, the identical method is: identifying the three sounds by lengthways three lists, identifying the three rhymes by transverse three rows, the intersectant is the whole identifying key-press of sound.

小键盘以输入第三键作为字符确认键，同时识别声韵，识别方法是：以纵向三列键识别三声；横向三排键识别三韵，纵横交合键位就是该音节的声韵全识别键。

The BCH coded authentication data is modulated by chaotic sequence and then embedded into the DCT domain of the image by using the owner's private key.The embedding process is controlled by Just Noticeable Difference of the DCT block.Users can extract the authentication data with the public key,while they can't get the private key to destroy or delete the watermark through the public key.

提出一种基于非对称水印的图像认证改进算法，算法中将经过BCH编码和混沌序列调制的认证信息作为水印，利用所有者私钥嵌入图像DCT域，嵌入过程根据DCT块的可视噪声阈值控制，用户可以利用公钥从水印图像中提取认证信息，但无法从公钥中获取任何私钥信息，从而无法破坏或删除水印。

A data gathering scheme MADG(movement-assisted data gathering),which makes use of the mobile base station for data collection,is presented.In this scheme,the base station moves in a stationary annularity area exploited for data buffering.The gathered data.are firstly forwarded into the buffering area and then collected by the mobile base station.

提出了一个利用移动基站协助数据收集的模式(movement-assisted data gathering，简称MADG)，它将基站移动区域设置为缓冲区，首先将数据沿最短路径传输到缓冲区内，然后在基站移动的过程中进行数据收集。

In this paper, three types of image data base is proposed, that is, attribute-oriented, feature-oriented and knowledge-oriented; the public fundamental structure of image data base system in each field is implemented, the improved expression of image geometrical feature is given, the strong command language and necessary auxiliary means to manage image data base are designed.
