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

rsa encryption which ask a user input must me be uppercase letter-rsa encryption which ask a user input must me be uppercase letter..

The class has a methode named make_CRC that gets a byte stream and start/end offsets then calculate and return a 16 bit CRC according to determined POLYNAMIAL.The POLYNAMIAL is a private field of the class.

目前企业面临的计算环境和过去有很大的变化，许多数据资源能够依靠网络来远程存取，而且越来越多的通讯依赖于公共网络公共网络（如 Internet），而这些环境并不保证实体间的安全通信，数据在传输过程可能被其它人读取或篡改。-currently facing the enterprise computing environment and past a great change, many data resources to be able to rely on remote network access, and more and more dependent on public communications networks public networks (such as the Internet), which environment is not a guarantee of the security entities communications, data transmission possible by other people read or tampered with.
