一种抗穷尽攻击的文件加密系统的设计与实现

Design and Implementation of an Encryption System Immune from Brute-Force Attack

针对加密系统易遭到穷尽密钥攻击的情况,利用杂凑函数和对称密码,设计出一种可有效地抗穷尽攻击的通用文件加密系统模型。该系统可以接受任意长度用户密钥,并可用于文档、语音和图像等各种数据加密。

As the encryption system is apt to be cracked by brute-force attack, a general encryption system model is established, which is immune from this attack and also can be used for text, voice or picture data encryption with keys of any length.
