摘要
介绍一种磁盘数据快速销毁算法,算法的初始密钥由单向散列算法、非对称加密算法、随机二进制填充和对称加密算法进行混合处理后,磁盘上的数据在存储时就可以处于一种理论上难以恢复的随机加密状态.在进行数据销毁时,只需要销毁极少量数据,就能够在极短时间内使大量数据不可恢复,从而实现磁盘数据的快速销毁.
ow to destroy the data on magnetic disc rapidly is always a problem.An algorithm for rapid data destruction was introduced,in which initial password was mixedly processed by one-way hash encryption algorithm, asyrmmetric encryption algorithm,random binary filling and syrmaetric encryption algorithm. This kind of hybrid encryption makes the data on magnetic disc to be at random and be hard to restore in theory. When the data needs to be destroyed, there is just a small quantity of data which needs to be destroyed, and then the large quantity of data will be unrecoverable in a very short time and thus the rapid destruction is realized.
