凯撒密码作为一种最为古老的对称加密体制，在古罗马的时候都已经很流行，他的基本思想是：通过把字母移动一定的位数来实现加密和解密。例如，如果密匙是把明文字母的位数向后移动三位，那么明文字母B就变成了密文的E，依次类推，X将变成A，Y变成B，Z变成C，由此可见，位数就是凯撒密码加密和解密的密钥。个人原创。(Caesar password as one of the most ancient symmetric encryption system in ancient Rome have been very popular, his basic idea is: by the letters move a certain number of bits to achieve encryption and decryption. For example, if the key is the number of bits of plaintext letters backward move three, the plaintext letter B into a ciphertext E, and so on, X will become Y-become a B,, and Z becomes C Thus, the median is the Caesar cipher encryption and decryption keys.

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
