查询词典 backspace key

Key management is the core problem of network system security, which deals with the correlative problems from key being generated to ultimately destroyed; it includes system initialization, key generation, key encasement, key distribution, key storage, key renovation, key destruction, etc. Thereinto key distribution and key storage are the two most intractable taches of key management.

密钥管理问题是网络系统安全中首要的核心问题，它是处理密钥自产生到最终销毁的整个过程中的有关问题，包括系统的初始化，密钥的产生、装入、分配、存储、更新、吊销和销毁等内容，而密钥的分配和存储是密钥管理中最为棘手的两个环节。

The method includes steps: digital watermark technique is adopted to hide information of key data in not key data codes of compressed image; under protection of digital watermark, using protective backup for key data detects whether normal transmitted key data is correct or not so as to detect error code; carrying out cyclic mutual backup by using macro blocks in same positions in front and back macro block set; embedding coded motion vector in form of digital watermark to DCT transformation coefficient, and ensuring that video data are not influenced as best as one can; when error code occurs, if key data backup is correct, then the backup replaces former key data; otherwise, using mean value of key data in adjacent macro blocks within same frame to replace former key data approximately.

本发明中，采用数字水印技术在压缩图像的非关键数据编码中隐藏关键数据信息；通过数字水印保护下的关键数据保护备份来检测正常传输的关键数据是否正确，由此来检测传输误码；用前后宏块组中相同位置的宏块进行循环相互备份；对运动向量进行编码，然后以数字水印的形式嵌入到相对不重要的DCT变换系数中，同时保证视频数据尽量不受影响；在误码发生时，如果关键数据备份正确，则直接替代原关键数据，否则用同一帧内相邻宏块的关键数据的平均值近似替代原关键数据。

To take advantage of the text arrangement functionality in devices with a keyboard, the component provides the '''insertAscii''' method. When Canvas or GameCanvas is used, the keyPressed method provides the ascii code of the button pressed. For normal keypad phones this is the ascii of the number pressed, for qwerty devices it will be the value of the key pressed. The device changes automatically the character set if the shift or numbers key is pressed and so the ascii received is different and corresponds to the intended key. The backspace character is also received as an ascii code, so it is not necessary to call in explicit way the delete function.

要充分利用键盘在设备里的文字安排功能，这个部份提供'''insertAscii'''方法，当Canvas或GameCanvas使用时，keyPressed方法提供按钮按下的ascii码，对於正常键盘手机来说这是按下数字的ascii，对qwerty设备来说它会是按下键的值，假如shift或数值键被按下该设备会自动改变字元集，所以所收到的ascii是不同的并且对应於所要的键，倒退键字元也会以ascii码来收取，所以没有必要用明确的方式来呼叫删除的函式。

A kind of knap sack public-key cryptosystem which is based on intractability of factoring big integer was proposed to introduce a trusted authority. TA generates the RSA public key and the private key with the RSA algorithm which transforms the primitive public key of knap sack public-key cryptosystem to the ordinary knap sack sequence, and it is publicize as a public key of knap sack public-key cryptosystem.
