摘　　要：传统的数据存证方法难以有效统一数据格式,容易出现数据处理结果不一致的现象。为了避免因此造成的存证效果差的问题,设计了基于安全散列算法的电子数据存证方法。根据安全散列算法实现消息处理,完成对填充位、消息长度、初始化缓存、消息主循环的处理,得到最简明的消息摘要,然后将大文件写入HDFS中,将小文件与信息摘要写入HBase中,并在设计HBase存储结构的基础上设计具体的存证流程。由测试结果可知,该方法不仅能够查看完整电子数据,还能够查看操作周期里的全部数据,具有高效的存证效果。The traditional data storage method is difficult to unify the data format effectively and is prone to inconsistency of data processing results.In order to avoid the problem of poor performance,an electronic data storage method based on secure hashing algorithm is designed.According to the secure hashing algorithm,the message processing was implemented,including the filling bit,message length,initialization cache and main loop processing of the message to obtain the most concise message digest.Then,the large file was written to HDFS,small file and information summary was written to HBase,and the specific storage process was designed based on the design of HBase storage structure.The test results show that this method can not only view the complete electronic data,but also view all the data in the operation cycle,with efficient storage effect.
