面向移动云的基于时间的增量备份方案

摘要

提出一种面向移动云计算的基于时间的数据安全增量备份方案，该方案针对移动设备的重要数据信息，将时间作为参数引入到数据加密中，依据时间阶段对用户上传的数据进行增量备份，既解决了对最新的敏感数据及时备份问题，又解决了由于备份密钥丢失造成的全部密文泄露问题。%A time-based data secure backup mechanism for moving the cloud was presented. Time was considered as a parameter into the data encryption for the important information in mobile device and backups the users' data ac-cording to the time period. It had not only solved the issue of the latest timely backup sensitive data, but also solved the entire ciphertext leak caused by missing the backup key.
