【摘要】：隨著云計算技術的迅速發(fā)展,云存儲的數(shù)據(jù)安全和隱私保護問題受到了人們密切關注。為了保護用戶的隱私數(shù)據(jù),云端一般是以密文形式存儲文件,給檢索帶來了不便。為了解決云環(huán)境中使用關鍵字查找密文文件的問題,有必要構建支持隱私保護的安全云存儲系統(tǒng)。基于MRSE方案并引入了TF-IDF規(guī)則,給出了云環(huán)境下動態(tài)模糊多關鍵字排行搜索方案。并將第三方審計機制加入到系統(tǒng)當中,進行文件可持有性驗證和密鑰管理。
[Abstract]:With the rapid development of cloud computing technology, people pay close attention to the data security and privacy protection of cloud storage. In order to protect the user's privacy data, the cloud usually stores files in the form of ciphertext, which brings inconvenience to retrieval. In order to solve the problem of using keywords to find ciphertext files in cloud environment, it is necessary to build a secure cloud storage system that supports privacy protection. Based on MRSE scheme and introducing TF-IDF rules, a dynamic fuzzy multi-keyword ranking search scheme in cloud environment is presented. Third-party audit mechanism is added to the system to verify file possession and key management.
