防止用DeDe软件反编译delphi程序-preventing anti-software compiler delphi procedures

著名图论问题之一。邮递员从邮局出发送信，要求对辖区内每条街，都至少通过一次，再回邮局。在此条件下，怎样选择一条最短路线?此问题由中国数学家管梅谷于1960年首先研究并给出算法，故名。-Well-known graph theory problems. Postman deliver a letter from the post office proceed to require every street within the right area, at least through the time, return to post office. Under these conditions, how to select a shortest route? This issue by the Chinese mathematician Mei Gu tube study in 1960, and gives the first algorithm, hence the name.

LZW算法基于转换串表(字典)T,将输入字符串映射成定长(通常为12位)的码字-LZW algorithm is based on converting Series (dictionary) T, the input string mapping into fixed-length (usually 12) the code word

是DES的编码密码算法，非常适合初学者学习，欢迎使用。-DES cryptographic algorithm is the encoding is very suitable for beginners to learn, welcome to use.

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
