中文摘要: 利用Word加密机制中存在的漏洞,实现了与加密密钥长度无关的常量时间破解,同时提出了基于MapReduce架构实现Word文档破解的方案,简化了分布式程序设计。实验表明了该方案的有效性,分布式计算中节点之间的并行消耗低。
Abstract:This paper makes use of the leak in Word encryption mechanism to decrypt word document in constant time, which has nothing to do with the key length. At the same time, an approach based on MapReduce paradigm is presented to to achieve Word document decryption, which simplifies the design of distributed application. The experimental result proves the validity of the proposed approach and the low consumption among distributed computing nodes.
