摘　　要：首先阐述了闪存数据应急销毁的研究现状,介绍零覆写、块删除和加密三种闪存数据销毁技术及Sun算法和Lee算法两种闪存数据销毁算法,并分析它们的优缺点。在此基础上,设计一个更为安全的闪存数据应急销毁算法,并评估其性能。We first expound the status of research in emergency data sanitization for flash memories, and then introduce three flash data sanitization techniques including the zero overwriting, block deletion and encryption, as well as two flash data sanitization algorithms of Sun algorithm and Lee algorithm, their advantages and disadvantages are analysed as well. On this basis, we present the design of a more secure emergency data sanitization algorithm for flash memory. At last, we evaluate its performance.
