摘　　要：针对传统软件离线授权方式不灵活、易被破解的问题,提出了基于AES加密算法的离线授权方法,设计了授权请求和授权校验流程。采用AES加密算法,并优化授权请求码、授权码的加密流程,加强对应用软件的保护;采用日期与剩余时间倒计时结合的方式,有效防止通过更改计算机系统时间延长使用期限;通过读写计算机注册表,保护应用软件同时便于用户使用。本方法主要应用于离线环境下,具有较高的安全性、易用性和实用性。Aiming at the problem of inflexible and vulnerable traditional offline software authorization method,proposes a software offline authorization method based on AES algorithm.Designs the flow of authorization request and authorization verification.Using the AES encryption algorithm and Optimizing the encryption process for authorization request codes and authorization codes to enhance the protection of application software.By combining the date and counting down the remaining time,effectively prevents extending lifespan by changing the computer system time.By reading and writing the computer‘s registries,protect the software and make it easier to use.This software authorization method is mainly applied in offline environment,and has high security,accessibility,and practicability.
