CRC-16算法的C语言实现（以常见的CRC-ITU为例引出的比特型算法）。-CRC-16 algorithm of the C language (in common CRC-ITU as an example of bit-based algorithm for extraction).

文件加密技术一例给文件加密的技术很多,其中又分为不同等级,以适合不同场合的需要.这里给出最简单的文件加密技术,即采用文件逐字节与密码异或方式对 文件进行加密,当解密时,只需再运行一遍加密程序即可.-file encryption technology to the case file encryption technologies lot, which will be divided into different levels, to suit the needs of different occasions. Here is the most simple file encryption technology, which adopts a case-by-byte file with the password or different ways to document encryption, decryption, only re-running again encryption procedures.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used (In VB- The same technique can be implemented in

组播密钥的批次更新算法，基于LKH的单次密钥更新方案和Batch Rekeying方案的原理、结构和密钥更新过程等。并着重对 Batch Rekeying 方案的性能与单次密钥更新方案作了简单的比较。 通过比较和分析得到结论:定时更新的Batch Rekeying 方案在更新开销上比单次更新更有优势 -Multicast key batch update algorithm, Based on the LKH single Rekeying program and the program Batch Rekeying principle, Rekeying structure and processes. And Batch Rekeying focused on the performance of the program with a single Rekeying program with a simple comparison. By comparing and analyzing conclusions : regularly updated Batch Rekeying program in the updated overhead than a single update more advantages
