传统的Java类文件保护方法存在被软件工具和反编译保护算法及利用其他接口进行破译等问题。通过在Java程序的运行环境———虚拟机中最底层Zip算法的开放源代码嵌入AES密码算法和RSA密码算法，提出一种安全性较高的基于混合密码算法的Java类文件保护方法。实验结果显示：该方法具有与AES和RSA一样的安全性，解决了传统保护方法的问题，比传统的方法有更安全的保护作用。

Based on traditional protecting Java class files,such as software tools,decompiling protection algo-rithm and API,a safer Java class file protection method is proposed by imbedding AES and RSA encryption al-gorithm into the code of Zip algorithms of Java virtual machine open-source,with the same security of AES and RSA.Our new technique solves the limitations of the traditional protection method.The experiment shows that the method is better and safer in protecting Java programs than traditional approaches.
