云数据安全去重技术研究综述
A Survey on Secure Data Deduplication Techniques in Cloud
摘要
Abstract
Data is often encrypted before stored on cloud servers,while different ciphertexts may be generated from the same data due to different encryption keys,thus implementing efficient data deduplication while ensuring data privacy is becoming a hot topic of research.This paper begins with an analysis of the primary issues of data deduplication technology,followed by a description of the system model for data deduplication and numerous security concerns.This paper examines secure data deduplication techniques from four perspectives:content-based encryption,proof of ownership,privacy protection,and data popularity for secure deduplication.The advantages,limitations,and common issues of various key data deduplication techniques are summarized.Finally,some future directions of data deduplication are presented.关键词
