摘要
为保护程序设计者的权益 ,探讨了软件有限使用和注册算法的改进 .在使用期限的改进算法中 ,放弃了常用的以软件安装日期为依据的计数方法 ,改进为以用户的前一次使用日期为依据的计数方法 ,使保护算法更为合理且不易被猜测 .在注册码算法的改进中 ,给出了一个很有实用价值的“一机一码”算法 ,结合实现过程的多级移位加密处理 。
For protecting the software designer's rights,improved arithmetics for software limited use and register engine have been discussed.In the limited use arithmetic,it gives up the normally used method which counts the days between the date of software installation and now,replaced by a new one which counts the different date since the latest use.This arithmetic is more reasonable and unpredictable.In the register engine arithmetic,it introduces a valuable One Computer One Code method,combineing with multilevel shift encrypting,it can implement a better protection effect.
