摘要 针对闪存的数据安全删除提出一种载体访问分层模型,讨论在各层访问并实现数据安全删除的优缺点,给出各层具有代表性的数据安全删除方法与技术。最后,提出一种基于控制器的数据安全删除方案,详细描述方案的实现流程以及各模块的主要功能。实验表明,该方法能够实现数据的安全删除。 Aiming at secure data deletion of flash memory, in this paper we prapose a hierarchical model of carrier access. We discuss the advantages and disadvantages of realising secure data deletion while accessing each layer, and give the representative methods and techniques of secure data deletion on each layer. At last, we propose a controller-based secure data deletion scheme, and expatiate on the implementation process of the scheme and the main functions of each module. Experiments show that this method can realise secure data deletion.
